2. Procella History and Technology

DTS Theatre with the very first Procella Audio system

Launched in the U.K. in 2006, Procella Audio was founded by Anders Uggelberg and Gerben Van

Duyl. At that time, Anders was Director of Cinema Technology for DTS Europe, and Gerben was

DTS‘s European Director of Business Development for Consumer Technology.

While at DTS, Anders, a THX trained and certified cinema designer with over 300 cinema and

professional studio designs to his credit, was asked to design and build a state-of-the art in-house

32 seat preview theater at the DTS Europe headquarters just outside London. Teaming up with

Gerben, the goal was to create a theater able to produce reference sound quality for playback of all

current and future cinema and home entertainment media, including the upcoming Digital Cinema

(DCI) standard, Blu-ray disc and other 24 bit/96KHz resolution playback systems. Of particular note

was the use of the theater for multi-channel music demonstrations to artists such as Queen and

Depeche Mode, in order to persuade them to have their own recordings remixed to 5.1. After

taking an exhaustive survey of available speaker systems, the duo determined that no existing

system could deliver the requisite high-resolution audio with uniform coverage to all 32 seats.

To meet these requirements, Anders designed a new speaker system that became the basis for the

current Procella systems. Nimbly balancing the requirements of the cinema and home

entertainment sides of DTS audio, Anders’ design accommodates both with equal capability and

prowess. Taking the best elements of cinema speaker design and applying the performance

standards and design elements of the best small studio and high-end audio loudspeakers, the

Procella system delivers high-resolution audio to each and every seat in the room. Once the design

Background

was finalized, the speakers were installed in the new DTS theatre in the summer of 2005 and

continue in operation there today.

To say the system was well received would be an understatement. Following the enthusiastic

approval of artists, engineers and producers that experienced and used the DTS system in their

professional capacity, Anders and Gerben realized the great commercial potential of the speakers,

leading to their departure from DTS and the creation of Procella Audio.

DTS Theatre with the first Procella speakers in screen baffle wall The original DTS system, which has evolved through several iterations into today’s P815, P8 and P18 loudspeakers, established the core principles of all Procella systems:

Identical Voice™

All screen and surround channel speakers are critically timbre matched, providing 'identical voices' around the room, regardless of the number of speakers or Procella models used.

High Frequency Compression Drivers

Compression drivers are used exclusively for high frequencies because of their wide dynamic range, high output levels and low distortion, particularly when compared to soft-dome tweeters.

Constant Directivity Waveguides

Each speaker utilizes a Procella-designed waveguide, which, along with carefully selected crossover frequencies, produces constant power response with superior dispersion characteristics and uniform coverage over a large seating area.

Advanced Crossover Designs

Procella-designed crossovers exhibit flat phase response and ultra-low group delay, with distortion-free air core inductors and polypropylene capacitors for maximum sonic purity.

Background

Digital Signal Processing (DSP)

All Procella amplifier models provide DSP control for active crossovers and very detailed fine-tuning of the acoustical result in a variety of room boundary conditions, making for great flexibility in system design and installation.

Sealed-Box Cabinets

All Procella speakers, including subwoofers, use sealed cabinets for superior transient response and group delay characteristics, as well as extended low-frequency subwoofer response.

Dual-Driver Dual-Amp Subwoofers

Procella’s highest performance subwoofers use two identical drivers, each driven by its own amplifier channel, for high efficiency, low distortion and 6 dB greater output than a subwoofer using just one driver.

3. System Design Parameters and Considerations

This section discusses the elements that should be taken into consideration when designing a

Procella Audio system. We encourage dealers and system designers to contact us in advance when

considering the use of Procella loudspeakers. We are happy to review system plans incorporating

Procella loudspeakers and to make suggestions for the appropriate Procella models. These reviews

are always free.

Room Design and Acoustic Treatment

Room design and acoustic treatment of both purpose-built and existing theater rooms is a complex

subject, and the details are outside the scope of this document. Systems incorporating Procella

Audio loudspeakers will reap an enormous benefit from proper room design and acoustical

treatment, so we strongly recommend that both are considered an integral part of any project’s

design and accounted for in the budget. Proper room treatment is not just absorbers; it involves

structural design and an understanding of absorption and diffusion, among many other things.

One note of guidance: Procella speakers use waveguides, rather than dome tweeters, which means

that the off-axis high-frequency energy they produce is much more uniform in frequency response

than the off-axis signals produced by most speakers. For acoustical treatment, this enables the use

of more diffusion and less absorption than designers typically must use with other speakers, and

this can produce better sonic results.

For dealers that do not have experience with room design and advanced acoustical room

treatment, engaging the services of an experienced acoustical designer can be invaluable. We can

refer dealers to designers that are familiar with Procella speakers. Also, subject to the time

availability of Procella engineers, we can also provide design services. This service will be provided

at a reasonable cost depending on the scope of a given project and the time required. Please

contact us for more details.

Listening Distance – Main and Surround Speakers

To start, let’s look at some key dimensions in the room where the system will reside. While overall

room dimensions are important, the initial consideration should be the distance from the speakers

to the listeners’ seats. This distance is the key factor in determining which loudspeakers should be

used for screen, surround, and height channels and how much amplifier power will be needed to

achieve the desired playback levels and dynamic range available for each listener. Subwoofer

requirements are primarily determined by the overall room dimensions and volume rather than the

distance to any given seat, and we will discuss subwoofers separately.

The direct sound power level produced by a speaker decreases as the inverse square of the

distance from the speaker. Simply put, each time you double the distance from a speaker, in free

field, the SPL will decrease by 6 dB (reduce the distance by half, and the level increases by 6 dB). In

rooms with multiple rows of seats, the direct SPL heard in the front row will therefore be higher

System Design

9


than the SPL heard in the back row. This means that in rooms with multiple rows of seats,

consideration should be given to the level that can be achieved in each row.

The reference level standard for cinema presentation, as defined by THX, requires each screen

channel to individually produce a level of 105 dB of direct sound at the listening position. The 105

dB level is based on two factors:

- all film sound mix facilities worldwide use an identical reference level of 85 dB for dialog when

mixing soundtracks, and

- the maximum channel signal level on digital film soundtracks is +20 dB (U.S. standard) and +18 dB

(European standard) higher than the dialog reference level, which is therefore 105 dB U.S. and 103

dB European.

That means that the creative team working on any film, worldwide, is able to create a soundtrack

with playback levels reaching as high as 105 dB per channel, with the knowledge that the

soundtrack will be reproduced at the same SPL they experienced during the mix, every time the

film is screened in a properly calibrated theater.

When all channels are playing back at maximum level, the total output is approximately another 5

dB, for a total of 110 dB!

The general rule for professional cinemas is that the sound system should be able to achieve

reference level to about 2/3 the depth of the room. This is a good standard for system design in

high-performance home cinema systems.

105 - 110 dB is quite loud, and therefore not all listeners will require this full capability, particularly

when there are room and budget limitations. For example, the person installing a P5 system in an

apartment living room is unlikely to have the same expectations as a client building a new,

dedicated home cinema room or a professional screening room. The system owner and designer

should explore these considerations as the system is being designed.

To determine the listening distance, measure from the front baffle of the center channel speaker to

the appropriate seat and/or to the 2/3 point of the room depth. The next section of this guide

includes a speaker selection chart that identifies the range of listening distances and power

requirements that will produce optimal performance with each Procella model used for screen and

surround channels.

Room Volume - Subwoofers

The second primary room dimension is room volume. Room volume is used generally to determine

subwoofer requirements, including specific models and the total number necessary to produce the

playback levels desired. In many rooms, volume is related to the listening distance from the screen

speakers to the seats, but in some cases (such as a large multi-purpose room with the theater

space at one end) it may not be.

System Design

To assist in selecting the correct Procella subwoofer model for each application, we will use cubic

volume. The goal is to help determine the minimum number of Procella subwoofer(s) and model

appropriate for a room. Room dimensions, acoustics and room treatments will affect subwoofer

requirements, sometimes to a great extent, so be aware that there is no universal formula for

calculating subwoofer requirements. We strongly recommend using at least the minimum

subwoofer recommendation per the Subwoofer chart on page 17, and always encourage the use of

multiple subwoofers.

In theaters with multiple seats, we strongly recommend a minimum of two subwoofers, and if the

budget and space allow, four subwoofers. Additional subwoofers can produce greater output, but

even more significantly, when they are deployed in multiple locations, the consistency of frequency

response across the seating area can be improved. This is an area where an experienced designer

can be extremely helpful, and we are also happy to provide assistance with your design.

For more details and information on choosing the Procella subwoofer for a specific application, see

Subwoofers on page 16.

Recommended Amplifier Power by Speaker Model

The P15A, P15AMP P10AMP, and some legacy speakers have onboard amplifiers delivering the

appropriate power for each model. Contact us if you have questions regarding one of these models.

The Procella DA05-DSP and DA06-DSP amplifiers are strongly recommended for use with all

Procella speakers. These amplifiers have custom DSP setting for speaker crossovers and

compensation for mounting locations. See Procella DSP Power Amplifiers on page 62 for more

information. Other high quality amplifiers can also be used, and in systems with more modest

budgets, such as those using P5 and P6 speakers, high quality receivers can also be used.

In order to achieve the maximum dynamic range, we always recommend using the maximum

amount of amplifier power that fits a project’s budget. Minimum power ratings are as follows:

P5/5V/5iW 75 Watts continuous minimum

P6/6V/6iW 100 Watts continuous minimum

P8 150 Watts continuous minimum

P28 200 Watts continuous minimum

P610 100 Watts continuous minimum for HF 250 Watts continuous minimum for LF

P815 150 Watts continuous minimum for HF 350 Watts continuous minimum for LF

P860 300 Watts continuous minimum for HF 900 Watts continuous (300W x 3) for LF

P10-FP 350 Watts continuous total (paralleled inputs) or 175 Watts continuous per driver

P15-FP 500 Watts continuous total (paralleled inputs) or 250 Watts continuous per driver

P18 1200 Watts continuous total (paralled inputs) or 600W continuous per driver

V18 1200 Watts continuous total (paralled inputs) or 600W continuous per driver

P15Si 350 Watts continuous minimum

P10Si 250 Watts continuous minimum

THX Approval and THX Certified Screening Rooms

The P815, P8 and P18 have all earned THX Approval for integration into professional facilities,

including THX Approved Screening rooms and pm3 rooms (Professional Multichannel Mixing and

Monitoring). Products that receive professional-level THX Approval go through a different testing

process than that receive the consumer-level THX Certification. THX Certified products are

intended for use in residential environments, which means among other things that they meet THX

requirements in rooms that are smaller than the ones where THX Approved products must

perform.

THX Approval of the P815, P8 and P18 enables their use in THX Certified Screening Rooms for

residential applications, as well as professional facilities. Integrators and clients interested in

creating a THX Certified Screening Room using Procella loudspeakers should contact us for more

information and assistance.

Immersive 3D Audio (Dolby Atmos, DTS:X, Auro-3D)

The breakthrough technology of immersive sound elevates the cinema experience to a new level

and creates new opportunities for multiple entertainment platforms that include games and music.

For 3D Audio, all existing Procella speaker models can be used as side and height channels when

mounted on side walls. For overhead channels, any Procella loudspeaker can be used when

properly mounted, but for practical reasons, the P5 family of speakers has proven to be the most

popular because of its compact size and its dispersion pattern.

Deciding on speaker placement can be rather complicated, because each 3D format has its own

recommended layout. The details of each are beyond the scope of this document, so we encourage

you to consult the documentation provided by Dolby, Auro-3D, and DTS for more information on

each format. Dolby and Auro-3D have installation guidelines with very detailed discussions of

speaker placement. You can find them at:

https://www.dolby.com/us/en/technologies/dolby-atmos/dolby-atmos-home-theater-installation-

guidelines.pdf

https://www.auro-3d.com/wp-content/uploads/documents/Auro-3D-Home-Theater-Setup-

Guidelines_lores.pdf

Please feel free to contact us when you are designing an immersive audio system. We have a good

deal of experience with the design and installation of such systems and are happy to assist you with

the system layout and speaker placement.

All three formats agree that the listener-level speakers should be located at the same height, using

the L/C/R speakers as a reference. Unlike 5.1 and 7.1 channel systems, the surround speakers

should not be placed two feet or more above the listeners’ heads. Instead, they should be a

maximum of one foot over the listeners’ heads.

System Design

We expect that most systems will be configured for Dolby Atmos. The Atmos home codec can

accommodate up to 34 discrete channels, but virtually all processors and receivers are designed to

reproduce 11 discrete channels plus a subwoofer. This enables two recommended system layouts:

7.1.4 channels and 9.1.2 channels.

The 9.1.2 channel layout has the significant benefit of including Left and Right Wide channels,

which are located between the screen and the side surrounds. However, this layout allows for only

two overhead speakers, so when it is used, the perceived movement of overhead objects will be

compromised. When there are multiple rows of seats, this layout is not recommended.

The 7.1.4 layout uses four overhead speakers, and provides for more precise overhead imaging and

front to back movement of sound. Most consumer Atmos systems will be configured for 7.1.4

channels. Regardless of the number of seats, the depth of the room, or an asymmetry of the

distance of the listening area to the front and back room walls, the four overhead channels should

be centered from front to back over the listening area.

In larger theaters, a 7.1.4 channel layout has limited resolution and will only be able to produce

good immersive sound for a small number of seats. We encourage system designers to consider

higher channel count systems to provide much greater imaging and smooth movement of objects

throughout the room. Home theaters with layouts beyond 7.1.4 channels (even in small rooms) will

produce a much more immersive experience and an overall sound much closer than that heard in

the original dubbing stage.

While many people think of Atmos primarily in terms of additional height information, there is a

significant enhancement to the immersive experience through the use of additional listener-level

speakers. Our strongest recommendations are for the use of Wide channel speakers and a middle

set of overhead channels in a 9.1.6 channel configuration. Given the current state of immersive

processors and receivers, there are a limited number of processors that will render this number of

channels. Bear in mind that when the reference standard for the 3D immersive experience is a

Dolby Cinema with 64 loudspeakers, a system with only 11 channels plus subwoofer may fall short

in trying to reproduce that experience. Advanced home theaters will strongly benefit from having

as many loudspeakers and discrete channels as the theater owner’s room and budget will allow.

Using Procella Speakers for Overhead Channels in Immersive 3D Audio Systems

One of the primary requirements for overhead speakers is wide dispersion, which is essential for

providing proper coverage and achieving timbre-matching among all the seats in the listening area.

Conventional speakers using dome tweeters have inherent dispersion limitations that makes this

very difficult to achieve. However, Procella loudspeakers use constant directivity waveguides that

provide a wide and controlled pattern of high frequency coverage. In keeping with the Procella

‘Identical Voices’ concept, the goal is to ensure that each listener hears from the overhead

speakers a tonal balance well-matched to the tonal balance of all the other speakers in the system.

For optimal sound, the height channel speakers should be mounted with the tweeter aimed at the

main listening position. Using conventional in-ceiling speakers may provide a clean look in the

System Design

room, but in many cases such speakers will compromise imaging and the overall immersive

performance. Procella’s in-ceiling solution, the P5iW, uses a circular waveguide to produce a

dispersion pattern that is essentially an 80 degree cone of sound, very close to Dolby’s

recommended 90 degrees of coverage. This allows the P5iW to be used when it is mounted flush to

the ceiling, but it will perform at its best when pointing at the main listening position.

Other Procella options using the same circular waveguide include the P5 and P5V. The P5 has the

form factor of a bookshelf speaker, and the P5V enclosure is tall and thin. Both produce an 80

degree circular radiation pattern, and offer multiple mounting options to facilitate pointing the

tweeter at the prime listening area. See Wall Mounting on page 40 for more details.

The P8 and P6/P6V speakers use an elliptical waveguide that provides wider vertical dispersion

than a dome tweeter, but still narrower than Dolby recommendations. When these models are

used as overhead speakers, this limitation can be eliminated by angling them towards the listening

position. In the case of the P8, its front baffle is angled at 7 degrees relative to its back baffle. When

the speaker is mounted with its back baffle flush to the ceiling, the tweeter sits at a 7 degree angle

relative to the ceiling. This can be useful when oriented to point at the seating area and listeners.

The P5, P5V and P6V have integral threaded inserts to enable use of a VESA articulated mounting

bracket. See Wall Mounting on page 40 for more details.

Additional Ear-Level Channels for Immersive 3D Audio Systems

Dolby Atmos allows for higher spatial resolution in the ear-level plane through the use of additional

side and back surround speakers. When designing a high channel count systems, consider first

including the Wide channels. These speakers are located on the side walls between the screen and

the Left and Right surrounds at a 45 to 60 degree angle. These speakers should always be aimed

towards the main listening position, rather than firing directly at each other. When additional side

surround speakers are used, particularly when there are more speakers than rows of seats,

immersion and imaging will be improved by aiming the surrounds towards the seating area.

When you are designing an immersive audio system, please contact us for guidance and feedback

on your system. We are very happy to consult with you to make sure that you are using the correct

loudspeakers and that they are placed for optimum performance. There is no charge for this

service.

4. Selecting the Proper Procella Speaker Models

The guidelines below show recommendations for Procella speaker as determined by the

requirements described above. Screen Channel recommendations are presented on the basis of

both listening distance and room depth.

Screen Channel Speakers:

Selection by Listening Distance (front baffle of center channel speaker to the seat)

For THX Reference Level Playback

Up to 2 meters (6½ feet) P6 and P6V (80 Hz crossover)

Up to 4 meters (13 feet) P8 (80 Hz crossover), P610 (full-range)

Up to 8 meters (26 feet) P815 (full-range), P28 (80 Hz crossover)

Up to 16 meters (53 feet) P860

For Standard Playback

Up to 3 meters (10 feet) P6 and P6V (80 Hz crossover

10 meters to 24 meters (33 to 80 feet) P860 (full-range)

Surround Channel Speaker: Selection by Screen Channel Speaker and Width of Room

P5 Screen Channel speaker Use P5 (any version) for all surrounds. Using a

crossover frequency of 90 – 120 Hz will increase the P5’s output.

System Design

15


P6 and P6V Screen Channel speaker - P6 and P6V are optimal.

- P5 (any version) can be used as side surrounds where the room is less than 5 meters (15 feet) wide and as back surrounds when the front row of seats is less than 5 meters from the back wall. Using a crossover frequency of 90 – 125 Hz will increase the P5’s output.

With the P8 Screen Channel speaker - P8 is optimal.

- P6 and P6V can be used as side surrounds when the room is less than 6 meters (20 feet) wide and as back surrounds when the front row of seats is 6 meters (20 feet) or less from the back wall. - P5 (any version) can be used with a high crossover frequency (see P6 and P6V Screen Channel above).

With P610 Screen Channel speaker - P6 and P6V should be used as side surrounds when the room is less than 6 meters (20 feet) wide and as back surrounds when the front row of seats is 6 meters (20 feet) or less from the back wall. - P8 should be used as side surrounds when the room is greater than 6 meters (20 feet) wide and as back surrounds when the front row of seats is 6 meters (20 feet) or more from the back wall. - P5, (any version) can be used with a high crossover frequency (see P6 and P6V Screen Channel above).

With P815 Screen Channel speaker - P8 is strongly recommended.

- P6/6V is acceptable as side surrounds when the room

is less than 6 meters (20 feet) wide and as back

surrounds when the front row of seats is 6 meters (20

feet) or less from back wall

With P860 Screen Channel speaker Use P8 for all surrounds. In extremely large rooms, the

P28 can be used.

System Design

16


Height Channel Speakers: Selection by Matching the Output of the Surround Speakers

The speakers used for height channels in Dolby Atmos, Auro-3D and DTS:X immersive audio

systems should have the same output capability as the listener-level surrounds in the system.

Ideally, the height channel speakers used should be the same model as the listener-level surround

speakers. However, it may be desirable for aesthetic or limited space reasons to use smaller

loudspeakers, such as one of the P5 models. If this is the case, use of a higher subwoofer crossover

frequency will enable the P5s to increase their output by reducing the amount of low frequencies

they will be required to reproduce.

Even though the audio content reproduced by the overhead speakers is mixed full-range, our

ear/brain mechanism localizes those sounds primarily through hearing the high frequencies. This

means that smaller speakers can be used with the low frequency content reproduced by the

system’s subwoofers. Dolby has taken this into account in the Atmos specifications, as Dolby Atmos

processors and receivers enable crossover points up to 180 Hz for the height channels.

When using any of the P5 family of speakers as overhead channel speakers, we recommend using a

subwoofer crossover point of between 100 and 125 Hz, or higher if desired. This will enable the

speakers to produce greater output and avoid a limitation of system dynamic range or maximum

playback level.

Subwoofers: Selection by Room Volume and Room Conditions As a reference:

The P15 is designed to produce +6 dB more output than the P15A, P15Si and P10.

The P18 is designed to produce +6 dB more output than the P15.

The V18 is designed to produce +3 dB more output than the P18.

When the P15Si and P10Si are operating purely as balancing subs in conjunction with other

subwoofers, they should not be taken into account in determining system low frequency output

capability.

System Design

17


Room Volume

These recommendations are for subwoofers in rooms with a medium low frequency reverb time.

Understand that these are guidelines, not precise specifications. Room construction, dimensions

and acoustics vary considerably from room to room, making it difficult to reduce subwoofer

selection to a simple formula. Experience counts; contact us if you have questions.

P10AMP, P10FP, P15A P15AMP and P15FP P18, V18. V6

One subwoofer up to 50m³ (1750 ft³) up to 100m³ (3500 ft³) up to 200m³ (7000 ft³)

Two subwoofers up to 100m³ (3500 ft³) up to 200m³ (7000 ft³) up to 400m³ (14000 ft³)

Three subwoofers up to 150 m³ (5250 ft³) up to 300m³ (10500 ft³) up to 600m³ (21000 ft³)

Four subwoofers up to 300 m³ (10500 ft³) up to 600m³ (21000 ft³) up to 1200m³ (42000ft³)

Room Conditions

The amount of low frequency loss, absorption and reverb in a given room can affect subwoofer

requirements. Rooms with low reverb time and/or low frequency loss will need more subwoofers

and rooms with long low frequency reverb times will have greater problems with standing waves

and resonances. In general, the smaller the room, the more pronounced the problems.

We recommend use of multiple subwoofers when possible, with two or four properly placed

subwoofers typically producing the best ratio of performance to cost. Subwoofer models may be

mixed in a room, meaning that P15As can be used as additional ‘balancing’ subwoofers in

combination with P18s or P15s used as the main subwoofer(s). The P15Si and P10Si are designed as

balancing subwoofers that can be used in combination with any Procella main subwoofer.

Some rooms can be considered ‘lossy’ at low frequencies because of the room design and

construction. This can occur in rooms where construction is not rigid, or when rooms have a large

number of windows, doors or open walkways. In some cases, lossy rooms produce better bass

quality than stiffly constructed rooms, because of reduced room mode effects. However, the loss of

bass energy must be compensated for with additional or larger subwoofers.

Low frequency absorption, when properly applied through room design and/or acoustical

treatments, is desirable as a way to avoid excessive nodes. This can be accomplished through the

use of techniques that include bass trapping. This is an area where the guidance of an experienced

and knowledgeable acoustician can be very beneficial.

When adding low frequency absorption to a room, bear in mind that the overall low frequency

energy in the room will be reduced. This may change the total subwoofer requirement and should

be considered when determining the models and quantities of subwoofers that you will use.

5. Positioning of Procella Speakers

Careful attention to optimal room positioning will help ensure maximum performance from

Procella speakers. Speaker positioning should be determined in the system design process, not

during the actual installation.

Our speaker location recommendations use cinema design guidelines and recommendations from

Dolby and THX. While the ideal theater environment is a purpose-built room, for most installations

the location of speakers will be dictated by room structure and/or the owner’s preference. Always

place Procella speakers in locations as close as possible to the ideal ones discussed here.

With the exception of the P5, P5V and P5iW, Procella speakers are designed for a vertical

orientation and should always be mounted with the tweeter above the woofer. Please contact us

for guidance if you are considering mounting a P6 or P8 with the tweeter below. The P28, P8, and

P6 should never be oriented on their sides. The P5 family of speakers uses a circular waveguide,

and therefore can be oriented either horizontally (wide) or vertically (tall). This circular radiation

pattern is desirable for overhead speaker use in 3D Audio systems, so the P5, P5V and P5iW are

highly recommended for this application.

Because the P860, P815 and P610 use separate cabinets for low and high frequencies, it is

acceptable to place those cabinets side by side, as long as the separation is less than half a meter.

Recommended Speaker Positioning for 5.1 and 7.1

The speaker setup for film sound in home cinemas and screening rooms places the speakers at

different angles to the positions typically used for music listening. Starting with the center channel

at the 0 degree position, the left and right channel speakers should each be placed at a 22.5 degree

angle to the left and right, respectively, which forms a total 45 degree angle between the speakers

at the listening position. The diagram shows an acceptable range of 22 to 30 degrees. While we

recommend the 22.5 degree position for film playback, the diagram shows the 30 degree option

sometimes chosen for music and now recommended for Dolby Atmos and Auro-3D.

When a Cinemascope 2.35:1 or wider screen is used, the left and right speakers should be located

behind the screen. Keep in mind the 45 degree angle from the listening position to the left and

right speakers described above. If the spacing between the left and right speakers is too close to

accommodate a narrower screen aspect ratio such as 16:9 or 4:3, the full sonic impact of the

widest screen format will be diluted. When masking is used for narrower screen sizes, the masking

must be acoustically transparent.

The side surround speakers on the adjacent diagram are shown at a minimum of 90 degrees. THX

recommends positioning the speakers at an angle of between 90 and 110 degrees, and Dolby

recommends 100 to 110 degrees. Our recommendation is to place the speakers just behind the

listeners’ ears, using the Dolby guidelines.

System Design

19


In a 7.1 channel system, the side surrounds

should also be located as shown on the

layout. Dolby recommends between 90 and

100 degrees, and THX says that 90 to 110

degrees is acceptable. Again, we recommend

behind the listeners at 100 to 110 degrees.

When there are multiple rows of seats, the

ideal design is to have a set of side surrounds

for each row, with each speaker located just

behind the listeners ears, plus a pair on the

back wall. If this is not possible, then the side

surrounds should be positioned symmetrically

along the side wall over the depth of the

seating area as measured from the center of

the front row to the center of the back row.

Placement for the back surrounds in 7.1

channel systems should be at approximately

the 150 degree position shown in the diagram above. This 60 degree spacing is recommended for

recorded material in discrete 7.1 channel formats such as Dolby TrueHD and DTS Master Audio.

Recommended Speaker Positioning for Immersive 3D Audio Systems

Determining optimal speaker placement for 3D Audio is complicated by the fact that Dolby Atmos,

Auro-3D, and DTS:X each have a unique recommended speaker layout. Dolby and Auro-3D have

published detailed documentation on speaker placement, but DTS has limited information

regarding recommendations as of this writing.

Please refer to the Dolby and Auro-3D

documents, as this section provides only a brief

overview. Links to the Dolby and Auro-3D

documents can be found on page 21.

For Dolby Atmos, there are two levels: a circle of

speakers placed at listener (or ear) level, and

two lines of speakers at the overhead level. The

listener level uses the same lateral placement of

speakers as the legacy 7.1 channel layout, with

the Left and Right speakers moved out to 30

degrees. Note that the recommended elevation

of the side and rear speakers is lower in Atmos

than in legacy Dolby. In 7.1, the side and rear

surround speakers are placed above the

System Design

20


listeners’ heads. In Atmos, the side and rear speakers should be located at the same height as the

L/C/R speakers, or slightly higher, up to about 1.25x the height of the L/C/Rs.

The overhead channels should be mounted on the ceiling with the left side overheads in line with

the Left speaker and the right side overheads in line with the Right speaker. See the diagram on

page 19. The front and back overhead speakers should be located on the ceiling so the angle of

elevation between the speaker and ear level at the main listening position is between 30 and 55

degrees. 45 degrees is ideal.

Regardless of the number of speakers, the array of overhead speakers should be centered front to

back over the listening area, even when the listening area is not centered in the room. The

separation between the left overhead speakers and right overhead speakers should be .5x to .7x

the width of the room. Once installed, the overhead speakers should be aimed at the main listening

position.

Dolby also allows for the use of Atmos Enabled upward-firing speakers in systems where speakers

cannot be ceiling-mounted and/or when there is a low ceiling. Procella does not make such

speakers; we recommend using speakers mounted overhead, as in Atmos cinemas.

Auro-3D uses two or three layers of speakers, in

9.1, 11.1 and 13.1 channel configurations. Like

Dolby, the Surround layer uses the legacy 5.1 or

7.1 channel lateral placements, with all speakers

at ear level or up to 10 degrees above ear level.

The Height layer consists of speakers mounted

high on the wall directly above the Left, Center,

Right, Left Surround and Right Surround speakers.

There must be 25 to 45 degrees difference in

elevation between the surround and height layers

(30 degrees is recommended). The high Center is

optional, depending on available processor

channels. There are no rear height channels.

The Top layer is also optional. It consists of a

single Top speaker (sometimes called Voice of God). When designing Auro-3D systems, keep in

mind that most processors are limited to 11.1 channels.

The full implementation of DTS allows for four layers, with one at ear level, two height layers, and

one layer below ear level. Presently, consumer DTS decoders are limited to 11.1 decoded channels

in a 7.1.4 channel configuration, so the full implementation is not available for home theaters. DTS

has suggested that essentially any reasonable speaker layout can be used for DTS:X playback. Based

on this information, we expect that speaker configurations based on either the Atmos or the Auro-

3D guidelines will work acceptably when playing back DTS:X material.

Screen Channel Speakers

Maximum cinema sonic impact and effectiveness is achieved with an acoustically transparent

screen and screen channel speakers mounted behind the screen in a baffle wall.

The screen channel speakers are ideally placed when their tweeters are on the same lateral plane.

The center channel can be placed at a different height, but imaging is optimal when all three

speakers are at the same height. We prefer locating the speakers above rather than below a

screen. The optimal vertical listening window for Procella is wider below the speaker than above it.

For the P8 and P6 speakers, the window extends from 5 degrees above the tweeter to 25 to 30

degrees below. With speakers located behind an acoustically transparent screen at the

recommended location of 5/8 of the screen height (or 1/2 for immersive 3D Audio systems), this

places listeners in the optimal window even when the speakers are above their ears.

Any time an acoustically transparent screen is used, a baffle wall should be constructed to mount

the speakers. Please see Baffle Wall Design and Construction on page 23 for more information on

baffle walls and their construction.

A baffle wall can also be used with a solid projection screen or flat panel display device. In this case,

the wall surface may be covered by fabric, with front speakers are concealed but not behind the

screen. For these installations, we recommend that the all three L/C/R speakers be placed at the

same height, preferably above the screen or display. This will produce the best imaging.

Whenever the speakers are mounted behind a screen or behind fabric used to conceal the

speakers, the grilles should be removed from the speakers.

Surround Speakers

Following the Identical Voice concept and cinema practices, Procella surround speakers are direct

radiators. We do not recommend using dipoles or other speaker configurations, as these violate

the Identical Voice philosophy and do not meet cinema and music industry recommendations for

playback of discrete multichannel film and music sources.

Few systems can use identical speakers for all channels. However, Procella’s Identical Voice

concept means that any combination of Procella loudspeakers can be used to produce excellent

results. For example, P8s perform superbly as surrounds when P860s, P815s, P610s, or P28s are

used for screen channels, and P6/6V are similarly excellent as surrounds with P610, P28, or P8

screen channel speakers. The P5/P5V/P5iW can be used with P6/6V or P5 family mains, and may

also be suitable for use as height channels because of their compact size.





System Design

22


See Recommended Speaker Positioning for 5.1 and 7.1 on page 18 for more details regarding room

placement. In 5.1 / 7.1 channel systems, they should be mounted at a height about two feet above

the listeners’ heads. In a 3D Audio system, they should be slightly above to about one foot above

ear level, depending on the distance from the listeners to the speakers and room height.

When there are multiple side surround speakers, each should be mounted at the same distance

from the floor (not ceiling) to be at the same relative height for each row. Take care to locate the

speakers with sufficient clearance in walkways to avoid the risk of head injury in a darkened room.

When there are multiple rows of seats, the ideal setup is to have a set of side surrounds for each

row, with each speaker at an angle slightly greater than 90 degrees relative to the row. If this is not

possible, the side surrounds should be positioned symmetrically along the side wall to cover the

depth of the seating area as measured from the center of the front row to the center of the back

row, with each speaker pointed to the ear height of a listener in the most distant seat in the row

just behind the speaker.

Height Speakers

Timbre-matching the speakers in a 3D Audio system is often challenging, given that main speakers

are typically larger than the ear-level surround speakers, and the overhead speakers may also be

smaller than the surround speakers. Even if identical speakers are used, the fact that speakers are

mounted on each wall and the ceiling means each listener will see a wide variety of angles among

the many speakers in the room. Procella’s ‘Identical Voices’ concept addresses this goal: for each

listener to hear a tonal balance from the overhead speakers as close as possible to all the other

speakers in the system.

For all listeners to hear a similar high-frequency balance from each speaker, the overhead speakers

must have wide dispersion at high frequencies. Speakers using dome tweeters have inherent

dispersion limitations that make this very difficult. However, Procella loudspeakers use constant

directivity waveguides with a much wider and better controlled pattern of high frequency

coverage, making them more suitable than conventional speakers for overhead applications.

Many speakers do not have sufficiently wide dispersion for such applications, and should not be

used. Dolby recommends that overhead speakers be oriented relative to the listening positions so

that the tweeters are aimed towards the listeners. This is good advice in all cases; we recommend

that all overhead speakers be aimed at the main listening position for the best possible results.

Other key requirements for overhead speakers are to have output commensurate with the main

speakers. Dynamic program material can require high output levels from the overhead channels,

and when those speakers are smaller than the main and surround speakers, bass management can

be highly useful. Using a higher subwoofer crossover point for the overhead speakers enables them

to produce greater output so they can keep up with the dynamics produced by the other speakers.

Using a crossover at 100 – 125 Hz with smaller speakers (such at the P5 family) is recommended

when they are used overhead, with the bass redirected to either the main subwoofer(s) or to a

local subwoofer placed to reproduce bass from a given direction (e.g., left side subwoofer).

6. Baffle Wall Design and Construction

For optimal performance with an acoustically transparent screen, the screen channels and

subwoofer(s) should be mounted in a baffle wall. A baffle wall is considered a best practice for

commercial cinemas and is a requirement for all THX certified commercial cinemas and professional

screening rooms. Proper use of a

baffle wall provides the best

combination of imaging, speaker

efficiency, and impactful cinema

sound.

Baffle wall installation eliminates

frequency response dips caused by

reflections off the back and side

walls, significantly increases the

maximum output capability of the

speakers by 6 dB – equivalent to

four times the power, and creates

an acoustic image the size of the

screen, not the speakers. It also

significantly improves tracking of

sonic images and screen images,

avoiding the jumps of sound from

channel to channel often heard in home cinema systems. Further, the baffle wall eliminates

diffraction from speaker cabinet edges, and reduces or eliminates sound reflected back through the

screen and from the back wall behind the screen.

The method described here is generally considered a standard for baffle wall construction.

However, we recognize that there are alternate methods practiced by some designers that also

produce excellent results. These include (but are not limited to):

Segmented walls with one section per screen speaker. They may be connected or separate, and the

left and right may be angled to provide a toe-in. This is also an option with curved screens.

Curved baffle walls, which provide toe-in and can be used with curved screens.

Partial baffle walls that do not span from floor to ceiling can provide many of the benefits.

The baffle wall should be constructed on a frame of 2x4s, with at least two layers of gypsum board

(sheetrock), and a third top outer layer of a solid sheet material (preferably MDF). It should span

from wall to wall and floor to ceiling. Make certain that it is very rigid. The total thickness should be

at least 1.5”, and the surface layer must be covered with material that is acoustically absorbent and

completely black, with an additional thickness of 1 - 1.5”. Be sure to acoustically treat the space

behind the baffle wall to eliminate resonances.

Three sources of materials suitable for acoustic treatment of the baffle wall surface are:

For each screen speaker, a cutout must be made appropriate for the

dimensions of the speaker. The baffle wall cutout dimensions for each

Procella model can be found on the individual tech sheets located in

Appendix A of this document. For height, the speakers should be

located so that their acoustic centers (the line at the lower edge of the

waveguide and the top of the grille) are at 5/8 of the distance from

the bottom of the screen to the top. Avoid locating the right and left

speakers too close to the side walls. Make sure you have the correct

locations – you won’t be able to move the speakers once they are

installed!

There should also be a cutout for mounting the subwoofer(s), which

should be located in the baffle wall and resting on the floor to take

advantage of room loading. Do not locate the subwoofer in the center

of the baffle wall. It should be offset to one side or the other. If two

subwoofers are used, they should be an asymmetrical distance from the center of the baffle wall

and from the right and left room walls.

Support for the screen speakers must be provided by platforms mounted to the baffle wall frame.

These platforms, or shelves, must be absolutely horizontal, have sufficient strength to support the

weight of the speakers and have enough solidity to be completely free from vibration and rattles.

All screen mounts also need to be secure and rattle and vibration-free. Do not create an enclosure

around the speaker – only a shelf for it to rest on. Use the provided Procella insulation feet for each

speaker, which go between the speaker and the platform/shelf. The subwoofer(s) should also be

mounted on Procella insulating feet.

System Design

26


When the left and right speakers are placed on

their platforms, they should be toed-in slightly

towards the center line of the room, with a

greater angle for small rooms and a lesser

angle for large rooms. Make sure you remove

the grilles any time that speakers are located

behind a screen, and in any case where they

will be located behind a fabric wall surface

used to conceal the speakers. We also strongly

suggest that the speakers be secured to the

back wall of the room with heavy-gauge wire or

the equivalent.

Make certain that the wall opening around the

speakers is filled and resilient, meaning that

once the speakers are in their final location, the

gaps between the speakers and the cutout in the baffle wall should be gasketed with sound

absorbing material such as insulation or dense foam. The space does not need to be sealed; just

filled.

Take care to see that the subwoofer does not cause any rattles by

being in contact with the baffle wall, the frame supporting the fabric

on the face of the wall, the screen, or any other object. Procella

subwoofers generate a lot of energy, so be sure to test for this once

everything is in place.

You must allow for air circulation and access to the amplifier/control

panels when using the P10AMP, 15AMP and P15A subwoofers. The

amplifier panels for the P10 AMP and 15AMP are located on the left

side of the cabinet when viewed from the front. The P15A amplifier

panel is located in a recess on the back baffle.

Alternative to a Baffle Wall

When it is not possible or practical to construct a full baffle wall, a less complicated option that

provides many of the benefits of a baffle wall can be achieved by flush-mounting the speakers on

the existing front wall of the room and treating that wall with the acoustic treatment materials

described above. The material should be 1 to 4 inches deep, and should cover the entire wall with

the exception of the speaker front baffles and the screen. The wall can be covered with acoustically

transparent fabric to conceal the absorbing material and the speakers.

7. P5 and P5V Installation Guidelines

The P5 and P5V are identical save for their cabinet shape, as they use the exact same drivers and

crossover. For simplicity, we will refer to both as the P5 in this chapter.

The P5 is designed for stand/shelf mounting on or next to a wall. Ideally, the back of the speaker

should be no more than five inches from the wall. The P5 uses a circular waveguide, which means

that the speaker can be oriented either vertically (tall) or horizontally (wide), with no change in its

dispersion characteristics. When the speaker is not flush mounted on a wall, the front left and right

speakers can be toed in towards the center of the room for optimal imaging.

For the best sound quality, the vertical angle between the location of the tweeter and the listeners’

ears should be kept to 30° or less above or below ear level. If necessary or desired, the speakers

may be mounted so that they tilt vertically. Typically, the speakers should be aimed directly at or

slightly above the prime seating location. In large rooms or rooms with a large listening area, the

standard is to aim the speaker vertically at a point 2/3 the depth of the seating area.

Mounting on a Wall

When used with a solid projection screen or flat panel display, the P5 can be placed above or below

the screen. Our recommendation is that whenever possible, the speakers should be placed above

the screen. While the center channel can be placed at a different height than the right and left

speakers, the best sonic imaging occurs when all three speakers are at the same height. Any time

the front speakers are not mounted at the same height, the height difference among the speakers

should be kept to a minimum. Avoid mounting the speaker so that its woofer is an equal distance

from the ceiling and side wall.


28


Several mounting options are available. Both the P5 and P5V have keyholes to enable a hanging

mount, one for a horizontal mount, and one for a vertical mount. The P5V has threaded inserts in

its back baffle to allow the use of any VESA 100 mounting bracket, including articulated brackets

that will allow the speaker to be aimed. For details, see Wall Mounting on page 40.

Speaker Stands

While not optimal, speaker stands can be used. On stands, the P5 should be positioned flush or up

to 5 inches from the back wall. They should typically be set up so that their tweeters are at ear

height. When this is not possible because the stand for the left and right speakers would place the

center channel in front of the screen, try to keep the differences in height between the center and

left/right speakers to a minimum. If the stands allow for vertical adjustment, be sure the tweeters

are aimed at the listeners’ ears. Stands with such adjustability that are relatively short in height

would help minimize the height difference between the center and left/right speakers.

When mounting the P5 on stands away from a wall, you will need to check the frequency response

of the speakers at the listening position and apply any necessary equalization to the low end of the

speakers. It will also be useful to set the subwoofer crossover to a higher frequency of 100 to 125

Hz.

During installation, check the distances from the speaker to the floor, to the side walls and to the

back wall. Each of these distances should be different, preferably by a foot or more, to minimize

sharp dips in the speaker’s response as heard at the listening position that are caused by half-wave

cancellation from early reflections.

P5 as a Surround and 3D Audio Height Channel Speaker

The P5 can be used as a surround speaker when the P6/6V/6iW, P8 or P28 are used as screen

channels, and of course can be used with P5 screen channels for a system with identical speakers

for all channels. When used as surrounds, the P5 and P5V can be mounted flush to the wall or on

brackets, with the tweeter above the woofer. The integral hanging systems is ideal for flush

mounting, and a VESA 100 bracket can be used to aim the speaker. For details, see Wall Mounting

on page 40.

For 3D Audio system overhead channels, the P5 provides a very wide circular radiation pattern of

80 degrees, due to the use of a circular waveguide. A VESA bracket that allows rotation and tilt is

recommended so that the speaker can be aimed at the main listening position.

For details on surround speaker location, see the discussions above. Note that the P5 is designed to

produce good response at angles up to 30° off the tweeter axis. When the speakers are mounted

close to the ceiling, the area above the speaker should be acoustically treated.


29


P5 Crossover to Subwoofer

The P5 is not a full-range speakers, so the low frequencies for each channel should be redirected to

the subwoofer. For the crossover to the subwoofer, a high-pass filter between 80 and 125 Hz with a

12 dB/octave Linkwitz-Riley characteristic is ideal. The internal crossover setting for the receiver or

processor should be SMALL, with the frequency set to between 80 and 125 Hz. For high power

applications, use 125 Hz. The higher the filter (crossover) frequency, the greater the output and

dynamic range of the P5V, which is especially important when the P5 is being used as an overhead

channel speaker in combination with larger Procella models as main channel speakers.

Break-In Period

The P5 will benefit from a break-in period before its first use. Right out of the box, it will not

perform to its full potential until it has been operated for a period of time. Tonal balance, clarity,

sensitivity and output will all improve after several hours of playing program material or pink noise

test signals. If possible, the break in should be for a continuous period at SPL in excess of 75 dB.

Recommended minimum break-in time: 10 hours for the P5.

More details on the P5 and P5V can be seen in Appendix A at the end of this document.


30


8. P5iW Installation Guidelines

Procella’s in-wall/in-ceiling speaker gives performance identical to the P5 in a package that

integrates attractively into any room environment. Unlike in-wall speakers with molded plastic

baffles, the P5iW is constructed of medium density fiberboard and incorporates an integral back

box. Its 80° circular radiation pattern enables in-wall installation of the speaker with either a

vertical or a horizontal orientation. Further, for in-ceiling placement, its circular radiation pattern is

desirable (especially for Atmos, DTS:X and Auro-3D overhead speakers), and superior to that of

dome tweeters, even when aiming mechanisms are used.

Installation of the P5iW

The P5iW secures to the wall through a clamping mechanism that uses four spring-loaded wall

clamps, one in each of the four corners. The wall cutout size is 17” / 430mm x 10.25”/ 260mm.

Take care to cut the wall accurately.

To install the speaker, first bring the speaker wires

through the wall cutout and secure them. They will be

attached after the speaker is installed. Set the

speaker into the cutout, routing the wires through

the cutout at the bottom center of the baffle.

Tighten each mounting screw until its mounting

clamps expand after being released from the metal

housing (see adjacent photo). Once all four are

released, secure the speaker by tightening each screw

until the clamp engages the back of the drywall. If necessary, the screws can be loosened until the

clamps re-engage the metal housing in order to remove the enclosure from the wall.

Once the speaker is secure, attach the speaker wires to the large gauge spring-loaded input

terminals on the front baffle just above the pass-through. Push any loose wire back through the

pass-through. The final step is to attach the speaker grille, which is held in place magnetically. If

you are installing the speaker in a ceiling, see Ceiling Mount Precautions below.

For ease of service, the drivers and crossover are mounted on a separate removable baffle, secured

to the enclosure/back box assembly by 10 screws. If desired, this baffle can be removed after

installation of the baffle/back box for safe storage until room construction is complete.

L/C/R Channel Use

When used with a solid projection screen or flat panel display, the P5iW can be placed above or

below the screen. Our recommendation is that whenever possible, the speakers should be placed

above the screen. While the center channel can be placed at a different height than the right and

left speakers, the best sonic imaging occurs when all three speakers are at the same height. Any

time the front speakers are not mounted at the same height, the height difference among the


31


speakers should be kept to a minimum. Avoid mounting the speaker so that its woofer is an equal

distance from the ceiling and side wall.

Using the P5iW as a Surround and 3D Audio Height Channel Speaker

The P5iW can be used as a surround speaker when the P6/6V, P8 or P28 are used as screen

channels, and of course can be used with P5 and P5V screen channels for a system with identical

speakers for all channels. When wall-mounted, the tweeter should be above the woofer.

The P5iW was designed with 3D Audio in mind. Its wide-dispersion, wide dynamic range and high

output make it a good choice for high-performance Atmos, DTS:X and Auro-3D installations.

One of the primary requirement for overhead speakers is wide dispersion, which is essential for

proper coverage throughout the listening area. Timbre-matching among all speakers in a 3D Audio

system is particularly important, meaning that each listener should hear a tonal balance from the

overhead speakers as similar as possible to all the other speakers. This requires wide dispersion at

high frequencies from the speakers located overhead. The P5iW produces a near-ideal circular

dispersion pattern of 80 degrees because its high frequency compression driver is mounted on a

circular waveguide that produces an 80 degree cone of sound.

Other key requirements for Atmos overhead speakers are to have output and power handling

commensurate with the main speakers. Dynamic program material can require high output levels

from the overhead channels, and limitations of underperforming speakers will be quickly exposed.

When the P5iW is used with larger Procella main speakers, a high subwoofer crossover frequency

up to 125 Hz can be used, ensuring that the overhead channels will not limit the system’s overall

dynamic range and maximum playback level.

For details on surround speaker location, see the discussions above. When the speakers are

mounted close to the ceiling, the area above the speaker should be acoustically treated.

Ceiling Mount Precautions – Safety Wire & Grille

Whenever a loudspeaker is mounted in a ceiling, safety considerations are paramount. As the

installer, you are responsible for making certain that the speaker is secured and that applicable

local regulations are complied with. At a minimum, the P5iW must be doubly secured with steel

wire safety cables in addition to the standard clamping mechanism.

Steel safety wire and eyehooks capable of supporting the 14.3 lb. / 6.5 Kg weight of the P5iW are

necessary. The wire needs to be run between eyehooks screwed into the P5iW back baffle and a

solid connection to a structural frame element above the ceiling.

In addition, while the magnets provided to secure the grille are powerful, we recommend adding a

couple of small screws to hold the grille in place when the speaker is overhead. One small screw on

each side at the center point about 2” / 50mm from the edge of the grille should do it.


32


P5iW Crossover to Subwoofer

The P5iW is not a full-range speakers, so the low frequencies for each channel should be redirected

to the subwoofer. For the crossover to the subwoofer, a high-pass filter between 80 and 125 Hz

with a 12 dB/octave Linkwitz-Riley characteristic is ideal. The internal crossover setting for the

receiver or processor should be SMALL, with the frequency set to between 80 and 125 Hz. For high

power applications, use 125 Hz. The higher the filter (crossover) frequency, the greater the output

and dynamic range of the P5V, which is especially important when the P5 is being used as an

overhead channel speaker in combination with larger Procella models as main channel speakers.

Break-In Period

The P5iW will benefit from a break-in period before its first use. Right out of the box, it will not




Recommended minimum break-in time: 10 hours for the P5iW.

9. P6 and P6V Installation Guidelines

The P6 and P6V are identical save for their respective cabinet orientations and shape. The P6 uses a

wide cabinet format, and the P6V uses a tall cabinet format. Either version can be used to produce

the same acoustical performance, with the choice determined according to the design

requirements of a given system. For simplicity, we will refer to both versions as P6 in this

handbook.

Both versions provide users with two mounting options – in wall and on wall. We do not

recommend mounting the speakers on stands away from walls because they are voiced for wall

placement. For screen channel use, the ideal installation condition is mounting in a baffle wall, but

the speaker can also be flush mounted on a wall or placed against a wall on speaker stands. The P6

should always be installed so that the tweeter and woofer are vertically oriented, with one above

the other as shown in the photos above. When the speaker is not flush mounted on a wall, the

front left and right speakers should be toed in towards the center of the room for optimal imaging.

For the best sound quality, the vertical angle between the location of the tweeter and the listeners’

ears should be kept to 30° or less when the speaker is above and 5° or less when the speaker is

below ear level. If necessary or desired, the speakers may be mounted so that they tilt vertically.

Typically, the speakers should be aimed directly at or slightly above the prime seating location. In

large rooms or rooms with a large listening area, the standard is to aim the speaker vertically at a

point 2/3 the depth of the seating area.

Baffle Wall

Mounting the P6 in a baffle wall enables the speaker to produce an additional 6 dB of output at low

frequencies. When the speakers are mounted in a baffle wall, behind an acoustically transparent

screen, they should be placed so that their acoustical center is at 5/8 of the screen height as


34


measured from the bottom of the screen. The acoustical center of the P6 is the lower edge of the

waveguide.

When installing the P6s in a baffle wall, be sure to use the insulation feet. The left and right

speakers should be toed-in towards the center of the room. Always remove the grilles when the

speakers will be used behind a screen. See Baffle Wall on page 23 for detailed instructions and

more information.

Flush Wall Mounting

The P6 and P6V are provided with a flush mount hanging bracket that makes wall mounting easy

and quick. For details on using this bracket, see Wall Mounting on page 40.

As a main speaker used with a solid projection screen or flat panel display, the P6 can be placed

above or below the screen. Our recommendation is that whenever possible, the speakers should be

placed above the screen. While the center channel can be placed at a different height than the

right and left speakers, the best sonic imaging occurs when all three speakers are at the same

height. Any time the front speakers are not mounted at the same height, the height difference

among the speakers should be kept to a minimum. Avoid mounting the speaker so that its woofer

is an equal distance from the ceiling and side wall.

Speaker Stands

If it is necessary to mount the P6 on stands away from a wall, you will need to check the frequency

response of the speakers at the listening position and apply any necessary equalization to the low

end of the speakers. It will also be useful to set the subwoofer crossover to a higher frequency of

90 or 100 Hz.

On stands, the P6 should be positioned about 2.5 to 3.3 feet or 0.8 to 1.0 meters from the back

wall. They should typically be set up so that their tweeters are at ear height. When this is not

possible because the stand for the left and right speakers would place the center channel in front

of the screen, try to keep the differences in height between the center and left/right speakers to a

minimum. If the stands allow for vertical adjustment, be sure the tweeters are aimed at the

listeners’ ears. Stands with such adjustability that are relatively short in height would help minimize

the height difference between the center and left/right speakers.

During installation, check the distances from the speaker to the floor, to the side walls and to the

back wall. Each of these distances should be different, preferably by a foot or more, to minimize

sharp dips in the speaker’s response as heard at the listening position that are caused by half-wave

cancellation from early reflections.

P6 as a Surround Speaker and as a 3D Audio Height Channel Speaker

The P6 can be used as a surround speaker when the P860, P815, P28 or P8 are used as screen

channels, and of course can be used with P6 screen channels for a system with identical speakers


35


for all channels. In many cases, such as when the speakers will be concealed in architectural

columns, the P6V may be preferred due to its narrower width. When used as surrounds, the P6 can

be mounted flush to the wall, with the tweeter above the woofer. The provided bracket is ideal for

flush mounting. For details on using this bracket, see Wall Mounting on page 40. The P6V has

threaded inserts in its back baffle to allow the use of any VESA 100 mounting bracket, including

articulated brackets that will allow the speaker to be aimed. For details, see Wall Mounting on page

40.

When used as a height channel speaker, the P6 should be mounted with the tweeter aimed at the

main listening position. The P6 uses an elliptical waveguide that provides wider vertical dispersion

than a dome tweeter, but this dispersion is still narrower than Dolby recommendations. The P6V

has integral VESA inserts to enable use of articulated mounting brackets. See Wall Mounting on

page 40 for more details.

For further details on surround and overhead speaker location, see the discussions above. Note

that the P6 is designed to produce good response at vertical angles up to 30° below the tweeter.

When the speakers are mounted close to the ceiling, the area above the speaker should be

acoustically treated.


The P6 is not a full-range speaker, so the low frequencies for each channel using a P6 should be

redirected to the subwoofer. For the crossover to the subwoofer, an 80 Hz high-pass filter with a 12

dB/octave Linkwitz-Riley characteristic is ideal. This is the same filter called for in THX

specifications, so when using a THX processor or receiver, set the filter/crossover to the THX

position. With non-THX components, set the crossover to SMALL, and if you are able to select the

frequency, choose 80 Hz. Higher crossover frequencies can also be used if needed.

10. P8 Installation Guidelines

The P8 is designed for baffle wall mounting and

flush mounting on a wall. It is not designed for

use on speaker stands or away from walls. For

screen channel use, a baffle wall is the preferred

method of mounting. The P8 should always be

installed so that the tweeter and woofer are

vertically oriented, with one above the other.

When the speaker is not flush mounted on a wall,

the front left and right speakers should be toed in

towards the center of the room for optimal

imaging.

For the best sound quality, the vertical angle

between the location of the tweeter and the

listeners’ ears should be kept to 30° or less when

the speaker is above and 5° or less when the

speaker is below ear level. If necessary or desired, the speakers may be mounted so that they tilt

vertically. Typically, the speakers should be aimed directly at or slightly above the prime seating

location. In large rooms or rooms with a large listening area, the standard is to aim the speaker

vertically at a point 2/3 the depth of the seating area.

Baffle Wall

Mounting the P8 in a baffle wall enables the speaker to produce an additional 6 dB of output at low

frequencies. When the speakers are mounted in a baffle wall, behind an acoustically transparent

screen, they should be placed so that their acoustical center is at 5/8 of the screen height as

measured from the bottom of the screen. The acoustical center is the lower edge of the waveguide.

When installing the P8s in a baffle wall, be sure to use the insulation feet, and always remove the

grilles when the speakers are behind a screen. The left and right speakers should be toed-in toward

the center of the room. See Baffle Wall on page 23 for detailed instructions and more information.

Flush Mounting on a Wall

The P8 is provided with a flush mount hanging bracket that makes wall mounting easy and quick.

For details on using this bracket, see Wall Mounting on page 40.

When used with a solid projection screen or flat panel display, the P8 can be placed above or below

the screen. We recommend placement above the screen when possible. The center channel can be

placed at a different height than the right and left speakers, but the best sonic imaging occurs

when all three speakers are at the same height. Keep any height difference among the speakers to

a minimum. Avoid locations where the woofer is an equal distance from the ceiling and side wall.


37


P8 as a Surround Speaker and as a 3D Audio Height Channel Speaker

The P8 can be used as a surround speaker with the P860, P815 and P610 screen channel speakers,

as well as with P8 screen channels, which would produce a system with identical speakers for all

channels. When used as a surround, the P8 should be mounted flush to the wall, with the tweeter

above the woofer.

When used as a height channel speaker, the P8 should be mounted with the tweeter aimed at the

main listening position. The P8 uses an elliptical waveguide that provides wider vertical dispersion

than a dome tweeter, but this dispersion is still narrower than Dolby recommendations. The front

baffle of the P8 is angled at 7 degrees relative to its back baffle. This means that when the back

baffle is mounted flush to the ceiling, the tweeter sits at a 7 degree angle relative to the ceiling.

This angle can be useful in pointing the tweeter at the seating area and listeners.

For details on surround speaker location, see the discussions above. Note that the P8 is designed to

produce good response at vertical angles up to 30° below the tweeter. When the speakers are

mounted close to the ceiling, the area above the speaker should be acoustically treated.

THX Approval

The P8 is THX Approved for integration into professional facilities, including THX Approved

Screening Rooms and pm3 Rooms (Professional Multichannel Mixing and Monitoring). This enables

its use in THX Certified Screening Rooms for residential applications as well.

More details on the P8 can be seen in Appendix A at the end of this document.


38



The P28 is a high performance, very high output

speaker. The P28 is designed for baffle wall mounting

and custom wall mounting using a third party or

custom bracket. It is not designed for use on speaker

stands or away from walls. For screen channel use, a

baffle wall is the preferred method of mounting. The

P28 should always be installed with a vertical (tall)

orientation. When the speaker is not flush mounted

on a wall, the front left and right speakers should be

toed in towards the center of the room for optimal

imaging.

The P28’s D’Appolito design creates an optimum

vertical listening window of 35°. For the best sound

quality, the vertical angle between the location of the

tweeter and the listeners’ ears should be kept to 15°

or less above or below ear level. If necessary or

desired, the speakers may be mounted so that they

tilt vertically. Typically, the speakers should be aimed

directly at or slightly above the prime seating

location. In large rooms or rooms with a large listening area, the standard is to aim the speaker

vertically at a point 2/3 the depth of the seating area.

grilles when the speakers will be used behind a screen. The left and right speakers should also be

toed-in toward the center of the room. See Baffle Wall on page 23 for detailed instructions and

more information.

Mounting the P28

The P28 is provided with a flush mount hanging bracket that makes wall mounting easy and quick.

For details on using this bracket, see Wall Mounting on page 40. In addition, there are two M6

threaded inserts located on the back baffle of the loudspeaker that are used to mount the P28 on a


39


Procella V6 to create a Procella P860. These threads are spaced 250mm apart vertically. See the

drawing in Appendix A of this document for the exact locations.

P28 as a Surround Speaker

For very large rooms, the P28 can be used as a surround speaker, typically with the P860, which

would produce a system with identical speakers above 80 Hz for all channels. A suitable mounting

bracket or custom flush mounting will be required, as we do not provide a mounting bracket with

the P28.

For details on surround speaker location, see the discussions above. Note that the P28 has limited

vertical directivity because of its D’Appolito design.

12. Wall Mounting

P6, P6V, P8 and P28

The Procella P6, P6V, P8 and P28 are provided with a flush mount wall bracket. In addition, the P6V

has threaded inserts in its back baffle to allow the use of any VESA 100 mounting bracket, including

articulated brackets that will allow the speaker to be aimed.

Flush Bracket Mounting

The flush mount bracket is secured to the wall through three 3/16” (4.8mm/R3) mounting holes.

The mounting hardware is not provided, so you’ll need three #8 screws for each speaker. The type

of screw will be dependent on wall construction. No hardware is necessary to attach the speaker to

the bracket – the bracket fits into a slot in the back baffle of the speaker. Secure the bracket to the

wall using the center hole first to help ensure that you mount the bracket absolutely level!

For post-construction installation in existing timber or metal framed rooms, we strongly

recommend that one of the bracket mounting screws be attached to a wall stud. The slot in the

back of the speaker is a couple of inches wider than the bracket, so once the bracket is in place, you

have a bit of play to establish the final lateral

location of the speaker. This should help you

to find a stud for one mounting screw. For

new construction, make certain that solid

blocking is attached to the wall frame at each

speaker location so that both mounting screws

can be driven directly into wood. Whenever

possible, it’s best to avoid the use of drywall inserts.


41


The bracket should be attached to the wall so that the angled flange points up towards the ceiling.

There must be a 1” (2.5 cm) space available above the speaker so that the speaker can be lifted

above the bracket in order to engage the bracket into the slot on the back of the speaker cabinet.

Before attaching the speaker to the bracket, attach the four provided silicone damping spacers to

the speaker. One should be mounted on each corner of the back baffle. These spacers reduce

unwanted vibration transmission and provide spacing for the speaker cable.

The cable outlet in the wall behind the speaker should be located within the area of the recessed

connector cup on the back of the speaker. The Product Tech Sheets in Appendix A detail the

location of both the mounting slot and the connector cup for all models.

To attach the speaker, simply lower the speaker so that the flange engages the slot in the back of

the speaker. Make sure that the flange is fully engaged in the slot and that the bottom of the

speaker is in contact with the wall surface, and that there is no risk that the loudspeaker can be

pushed from below up and off the bracket. If there is any doubt, take additional steps to secure the

speaker so it cannot be pushed upwards.

When mounting the P6 or the P8 behind an acoustically transparent screen, the acoustical center

(bottom edge of the waveguide) should be at a height 5/8 of the distance from the bottom of the

screen to the top of the screen.

P6V VESA Bracket Mounting

The P6V has threaded inserts in

the middle of its back baffle for

mounting a VESA 100x100 bracket.

You have a wide variety of

brackets from multiple suppliers to

choose from.

See the adjacent drawing for the

location of the inserts. Please note

that the P6 does not have these

threaded inserts.

The mounting screws for the

threaded inserts are M4 machine

screws. Follow the bracket

manufacturer’s installation instructions for mounting. Make sure the bracket will support 20.1 lb. /

9.1 Kg and that it is securely mounted to the wall, preferably to a stud.

P6V Back Baffle


42


P5 and P5V

The back baffle of the P5 and P5V provide two

options for mounting the speaker. The speaker can

be hung flush to the wall using a keyhole mount, or it

can be mounted with a VESA 100x100 bracket. See

the adjacent diagrams for the location of the keyhole

mounts and threaded inserts for a VESA bracket.

Keyhole Mounting

The P5 and P5V have multiple integral keyhole

mounts. One is provided for horizontal mounting of

the speaker and one (P5) or two (P5V) are provided

for vertical mounting of the speaker. One of these

will be used to hang the speaker on a single

mounting screw. A stud mount is always preferred,

but when necessary a wall insert can be used as long

as it is capable of handling the 11 lb./5 Kg weight of the

P5/P5V.

Before attaching the speaker to the bracket, attach the

four provided silicone damping spacers to the speaker,

one on each corner of the back baffle. These spacers

reduce unwanted vibration transmission and provide

spacing for the speaker cable. The cable outlet in the wall

should be located within the area of the recessed

connector cup on the back of the speaker. See the

adjacent drawings or the P5 and P5V Tech Sheets in

Appendix A for the location of the mounting slots and

the connector cup.

To use the keyhole mounts, simply hang the speaker so

the mounting screw engages the slot in the back of the

speaker. Make sure that the screw is fully engaged in the

slot, that the bottom of the speaker is in contact with the wall surface, and there is no risk that the

loudspeaker can be pushed from below up off the screw. If there is any doubt, take additional steps

to secure the speaker so it cannot be pushed upwards.

P5 and P5V VESA Bracket Mounting

The P5 and P5V have threaded inserts in their back baffles for mounting a VESA 100x100 bracket.

You have a wide variety of brackets from multiple suppliers to choose from.

The drawings on page 42 show the locations of the inserts. The mounting screws for the threaded

inserts are M4 machine screws. The square mounting layout enables the P5 or P5V to be mounted

either horizontally or vertically. Follow the bracket installation instructions for mounting. Make

sure the bracket will support 11 lb. / 5 Kg.

When mounting either P5 behind an acoustically transparent screen, the acoustical center (bottom

edge of the waveguide) should be at a height 5/8 of the distance from the bottom of the screen to

the top of the screen.

The P610 is a very high performance, high

output loudspeaker that will produce

reference quality audio in the finest home

cinemas. It will typically be used in a baffle

wall, behind an acoustically transparent

screen. It can also be used as a free-

standing speaker, either for home cinema

applications, or for high-resolution

multichannel or two channel playback.

The P610 uses a P6 mid/high frequency

module and a P10Si low frequency

module. The P6 is a standard Procella P6,

securely mounted to the top of the P10Si

by a mounting bracket. The bracket allows

horizontal rotation of the P6 for toe-in

purposes, up to about 20 degrees.

Each cabinet has a separate set of binding

post inputs for biamplification. The P610

requires two sets of speaker cables to be run from the power amplifier to the loudspeaker. DSP is

required for the low frequency/midrange crossover (the midrange/high frequency crossover is

passive and built into the upper cabinet). The Procella DA05-DSP and DA06-DSP amplifiers have the

necessary DSP crossover settings and are the specified amplifier for the P610. See Procella DSP

Power Amplifiers on page 62.

In any installation, always use the provided vibration isolation mounting feet under the cabinet.

Baffle Wall

Mounting the P610 in a baffle wall enables the speaker to produce at least an additional 4 dB of

output at low frequencies. When the speakers are mounted in a baffle wall, behind an acoustically



waveguide on the P6 cabinet (mid/high frequency module).

When installing the P610 in a baffle wall, be sure to use the insulation feet, and always remove the

grilles when the speakers will be used behind a screen. The P6 top cabinet of the left and right

speakers should be toed-in towards the center of the room, and the bracket allows for rotation of

the cabinet. See Baffle Wall on page 23 for detailed instructions and more information.


45


P610 Full-Range Operation and Crossover to Subwoofer

The P610 meets cinema standards as a full-range speaker, with low frequency extension to 40 Hz or

below, depending on the installation. This is the same configuration as the speakers used in

dubbing stages. Because of this extension below the commonly used 80 Hz crossover point, the

speaker can be operated with the processor set to use the FULL-RANGE or LARGE speaker setting

for each channel using the P610, with the Subwoofer set to YES or ON. If possible, set the processor

so that the low-pass for the subwoofer is below 50 Hz.

Among the benefits of operating the P610 as a full range speaker is having the low frequencies

between 40 and 80 Hz produced by 15 inch drivers in three locations, which improves the

soundfield and uniformity of frequency response throughout the room. You will hear a more

coherent and impactful sound from the screen channels. Distortion is also lower in that range with

more drivers operating.

Alternately, the P815 can be bass managed to redirect bass to the subwoofer, with typical settings

between 40 and 60 Hz, depending on room conditions. We recommend that once the speakers are

installed in the room, measurements and listening tests be conducted to determine the best mode

of operation, as there is great variation in rooms through this critical frequency range. In some

rooms, no bass management will be best, but in other rooms, bass management will be necessary

for smooth low frequency response.

The P815 is a very high performance, high output

loudspeaker that will produce reference quality

audio in the finest home cinemas. It will typically

be used in a baffle wall, behind an acoustically

transparent screen. It can also be used as a floor

standing speaker, either for home cinema

applications, or for high-resolution multichannel

or two channel playback.

The P815 is a biamplified speaker, requiring two

amplifier channels per speaker. It combines a P8

mid/high frequency module with a P15Si low

frequency module. The P8 is a standard Procella

P8, securely mounted to the top of the P15Si by a

mounting bracket. There are two mounting

brackets options. The vast majority of cases will

use the 7° Bracket, which supports the P8 so that

its front baffle is perpendicular to the floor. Where

the high frequency radiator needs to be angled

down to properly aim at the listening area (very

large rooms), the 0° Bracket supports the P8 so

that it angles downward at a 7° angle (the natural

angle of the cabinet). If you do not have the

necessary bracket, contact Procella Audio or your

distributor.

Both bracket versions allow horizontal rotation of the P8 for toe-in, up to about 20 degrees.

Other Considerations

Cutouts on the side of the P15Si woofer cabinet can be used as hand grips to make the cabinets

easier to move. In any installation, always use the provided vibration isolation mounting feet under

the cabinet.

Earlier versions of the P815 used the LF815 low frequency module. This loudspeaker performs

identically to the P15Si, but used a slightly larger enclosure. If you have any questions regarding the

LF815, please contact Procella Audio.

Biamplifying the P815 with the Procella DA-06DSP Power Amplifier

The P815 is a biamplified speaker, requiring two amplifier channels per speaker and two sets of

speaker wires running to each speaker location. We strongly recommend using the Procella DA06-

DSP amplifier with the P815, because it provides the necessary DSP settings for the active crossover

and speaker equalization. See Procella DSP Power Amplifiers on page 62 for information on the

DA06-DSP. The proper preset configuration for the P815 is on page 63.

The P860 is an extremely high performance, extremely high

output loudspeaker that will produce reference quality

audio in the largest home cinemas, screening rooms and in

small to mid-size commercial cinemas. It will typically be

used in a baffle wall, behind an acoustically transparent

screen. It can also be used as a floor standing speaker when

maximum output and resolution are required, whether for

home cinema applications or for multichannel and two

channel music playback.

The P860 uses a P28 mid/high frequency module and a V6

low frequency module. The P28 uses the same compression

driver as the P8, adding a second 8 inch woofer in a

D’Appolito configuration for increased output. The V6

module contains six 10 inch woofers mounted in a push-pull

V-configuration that increases output and lowers harmonic

distortion. The P28 mounts securely to the V6 enclosure

with a mounting bracket that allows the P28 module to be

rotated horizontally for toe-in, up to about 20 degrees.

Biamplifying the P860 with the DA-06DSP

The P860 must be biamplified with the Procella DA06-DSP

power amplifier. Two amplifiers are required for each P860,

although for L/C/R installations, a total of five amplifiers is

sufficient. For each speaker, one amplifier channel connects

directly to the P28 mid/high frequency module, and two

channels connect to the V6 low-frequency module through two sets of binding posts. Each speaker

location requires three sets of speaker cables running from the amplifier to each P860. See Procella

DSP Power Amplifiers on page 62 and the DA06-DSP User Guide for the proper preset configuration

with the P860.

Older versions of the V6 used three sets of binding posts and required three amplifier channels.

Contact us for wiring instructions if you have a V6 with three sets of inputs.


Because of the complexity and expense involved with P860 system projects, we will be happy to

provide additional assistance and guidance for both the planning and installation phases of these

projects. Please contact us in advance so that we can help to ensure the highest possible

16. Subwoofer Installation Guidelines: V18, P18, V6, P15, P15A, P10

These instructions and

recommendations

apply to all Procella

subwoofer models.

Guidelines for selecting

the proper model and

number of subwoofers

to be used in a given

system can be found in

Selecting the Proper

Procella Speaker

Models on page 14. If

you have additional questions or need more guidance with subwoofer installation, please contact

us. We also strongly recommend the use of an experienced acoustical designer when a project’s

budget allows.

Location of the Subwoofer(s)

The very shallow depth form factor of Procella subwoofers (except for the V18) gives installers a

great deal of flexibility in determining where they can be located in a room. To also increase

installer flexibility, we have located the input connectors and controls on the left side of the cabinet

(P15AMP) or on a recess in the back baffle (P15A), enabling installation directly against walls.

Finding the ideal location for a subwoofer, particularly in smaller rooms, can be a challenge. The

greater the number of seats in a room, the greater the challenge. Therefore, experimentation with

placement before final installation is highly recommended. Whenever possible, response

measurements should be taken at the listening position rather than relying solely on a subjective

listening analysis. When there are multiple seats in the room, the goal should be to minimize the

variance of response among the seats with subwoofer placement. Optimizing for a single seat will

typically cause a great deal of variation in response in the other seats.

For practical and performance reasons, the subwoofer should rest on the floor, placed against or

very close to one or more room walls. The front wall is the preferred location. Subwoofers can also

be built into a wall. We recommend starting with a single subwoofer against the front wall in an

off-center position, either to the left or to the right of the center channel speaker. Generally

speaking, it is not a good idea to place a single subwoofer at the center point of the screen or room

front wall (or at the center point of any wall). In most rooms, center wall placement will produce

significant cancellation of low frequencies due to a null. Placing the subwoofer against the front

wall in an off-center position typically produces smoother bass than a center position.

In any case, placement against a wall produces increased SPL because this placement allows the

subwoofer to couple with the wall, resulting in an extra 3dB of output. Even greater coupling


53


occurs when the subwoofer is moved into a corner, which produces an additional gain of 3dB. It’s

important to note, however, that the increased output of corner placement comes from driving

room modes to the maximum extent, and may not produce the best result.

Another placement consideration is room structure. Subwoofer loading improves with the

structural solidity of the wall it is placed against, so this should be taken into account when

evaluating potential locations. For example, placement against an exterior wall will often give

better results than placement against an interior wall. Avoid locations near doors, windows and

walkways.

Keep in mind a couple of considerations when experimenting with subwoofer placement. Procella’s

internal and external amplifiers have controls to optimize the subwoofer’s response by taking into

account the room boundary condition of its location. If you move a subwoofer to a different

location, you may need to change the DSP settings. Also, remember that when you move a

subwoofer closer to or farther away from a wall or a corner, the overall level of the subwoofer will

change, which may require an adjustment of the subwoofer output level.

Multiple Subwoofers

We strongly recommend the use of multiple subwoofers. When a system has multiple seating

positions (except in an auditorium-sized space), bass quality and levels will change significantly

from seat to seat whenever a single subwoofer is used. This is simply the nature of small room

acoustics. A good solution to this problem is to use additional subwoofers to smooth out the room

modes, which produces a flatter response and minimizes the differences among the listening

positions. Further benefits of multiple subwoofers include more dynamic range and lower

distortion for any given playback level.

To optimize response among the seats, each subwoofer should be placed in a different location.

Generally, when two or three subwoofers are used, they should be placed asymmetrically along the

room’s boundaries, and when four subwoofers are used, they should typically be placed

symmetrically. Because the acoustics of rooms vary so greatly and are extremely difficult to model,

it is very difficult at best to predict the best placement for any given room. However, there are a

few combinations that you may find useful as a starting point when deploying multiple subwoofers

in a room.

Two subwoofers

- Front and side – one subwoofer on the front wall, between the center and either the right or the

left speakers, and the other on either side wall, at a different distance from the front wall as the

first subwoofer is from the side walls.

- Front and back – one subwoofer centered on front wall and the second centered on the back wall.

This technique can also be used with each woofer centered on a side wall.


54


Four subwoofers

- Midpoints – each subwoofer is located at the midpoint of a wall, with the main subwoofer against

the front wall. The main subwoofer can also be offset from the center position.

- Corners – each subwoofer is located in a corner. Requires a room with four corners and no

adjacent doors.

For additional guidance, please contact us or an experienced acoustician. When using more than

one subwoofer, it is acceptable to use a larger model (say, the P18) as the main subwoofer and

smaller models (P15, P15A, P10 or P10Si) in the secondary or ‘balancing’ locations. The P15Si and

P10Si were specifically created for use as a balancing subwoofer. See the section below for a more

detailed discussion of using the P15Si and P10Si as a balancing sub.

There is an alternative benefit to using more than one subwoofer. When the goal is to achieve the

greatest efficiency and maximum output, you can place the subwoofers in close proximity. The

subwoofers’ outputs will couple, resulting in a total of 3 dB more output than they would produce

when placed in separate room locations. When using this technique, to avoid buzzing or other

undesirable noises, do not allow the cabinets to contact each other unless they are securely

connected. Bear in mind that placing the subwoofers in the same room location will not provide

the response smoothing benefit discussed above where multiple subwoofers are placed in different

locations.

Baffle Wall

An excellent location for the main subwoofer(s) is in a baffle wall. This produces the same 3 dB

coupling gain that exists with placement against a wall. Additional subwoofers may be located in

other parts of the room, but when a baffle wall is used, the main subwoofer(s) should always be

located in the baffle wall.

When installing the subwoofer in a baffle wall, be sure to use the insulation feet under the cabinet.

Always remove the grilles when any Procella speaker will be used behind a screen. See Baffle Wall

on page 23 for detailed instructions and more information.

Subwoofer Crossover

There is no crossover or low-pass filter built into Procella subwoofers, so the input signal must be

low-pass filtered in the processor, preamp or external DSP/electronic crossover. The crossover

frequency depends on the main and surround speakers being used, but will typically be 80 Hz. 80

Hz is the correct frequency for the P6/6V/6iW, the P8, and the P28. The compact P5 and P5V can

use a higher crossover frequency up to 125 Hz for high power applications. For the full-range P860,

P815 and P610, a crossover is not necessary but may be beneficial. If room characteristics require a

crossover, the frequency should be no lower than 40 or 45 Hz. The low-pass filter should have a 24

dB/octave Linkwitz-Riley characteristic.


55


Always use a single common bass channel to feed the main subwoofer(s). If you are using multiple

subwoofers, you may find a benefit from directing bass to a local secondary subwoofer, such as a

subwoofer used for the left surround and left overhead channels. We still recommend that the low

frequency content of all channels be fed to the main subwoofer(s) so that the benefit of consistent

low frequency response throughout the listening area is maintained..


For the P15AMP, P10AMP and P15A subwoofers, which have onboard amplifiers, take care in

installation to insure that there is sufficient space for airflow around the amplifier. It is normal for

the amplifier to be rather warm to the touch. There is a warning LED that will blink if the amp is

overheating.

The P15, P18 and V18 have cutouts on their left and right side baffles that can be used as hand

grips when you need to move the cabinet. Be extremely careful when moving subwoofers—

moving the P15, P18, V6 or V18 is a two man job.

In any installation, always use the provided vibration isolation mounting feet under the cabinet.

Removing the speaker grille will eliminate any possibility of audible resonance from the grille or

grille fabric and is highly recommended, especially for the P15, P18, V18 and V6.

Break-In

Procella subwoofers will benefit from a break-in period before their first use. Right out of the box,

they will not perform to their full potential until they have been operated for a period of time.

Tonal balance, clarity, sensitivity and output will all improve after several hours of playing program

material or pink noise test signals. If possible, the break in should be for a continuous period at SPL

in excess of 75 dB.

Recommended minimum break-in time:

P15A, P15, P10 15 hours

P18, V18 and V6 20 hours

Using the V18, V6, P18, P15-FP and P10-FP with Procella DA Series Amplifiers

The V18, P18, P15-FP and P10-FP are designed so that the power amplifier is located separately,

typically rack mounted. Either the Procella DA05-DSP or DA06-DSP can be used, depending on the

model and power requirements. Two sets of speaker cables must be run from the amplifier

location to each subwoofer. See Procella DSP Power Amplifiers on page 62 for information on the

Procella power amplifiers and for system configuration information. To use these subwoofers with

a non-Procella amplifier, DSP is required to produce the proper frequency response of the

subwoofer. Contact us for specific guidance for these installations.

The P15A, P15AMP and P10 AMP are available only with an onboard amplifier and cannot be used

with the DA05-DSP or DA06-DSP.

17. Balancing Subwoofers: P15Si and P10Si

As discussed above, in screening rooms and home cinemas with multiple seats and a single

subwoofer, the frequency response and SPL at low frequencies will vary, often significantly, from

seat to seat. To tame low frequency room modes and provide more consistent bass response

throughout the listening area, multiple subwoofers can be used, with each placed in a separate

room location. When done properly, this can greatly improve the overall listening experience and

can enable further improvement by making the use of single-channel low-frequency equalization

possible.

The P10Si and P15Si are designed

to facilitate the usage of multiple

subwoofers to produce more

consistent bass performance.

These speakers are also used as

the low frequency element in the

full-range P610 and P815

speakers, respectively.

The P15Si has a single 15 inch

driver, and the P10Si has a single

10 inch driver in a small footprint

cabinet that can be used in either

a horizontal or a vertical

orientation.

Both provide the capability to

improve low frequency performance when used in combination with any of Procella’s larger

subwoofers. When any of the larger Procella subwoofers (V18, V6, P18, P15, P10) is used as a main

subwoofer, multiple balancing subwoofers (typically one to three) can be placed in different room

locations to smooth the low frequency modes of the room. See the Multiple Subwoofers section

above for a discussion of methods of determining where the additional subwoofers should be

located.

The P15Si and P10Si are passive subwoofers with no onboard amplifier option. A single pair of

speaker cables must be run from a remote amplifier to each location where the balancing

subwoofer will be placed. The recommended amplifier power is a minimum of 200 watts at 8 ohms,

with 300 watts or more preferred. The Procella DA05-DSP and DA06-DSP are recommended for use

with single and multiple balancing subwoofers. See Procella DSP Power Amplifiers on page 62 for


58


more information.

Once the variance of response among the seats has been minimized, the use of a single channel of

equalization applied to the main subwoofer channel becomes possible. Without balancing

subwoofers, the seat-to-seat variation is typically too great to be accurately compensated for with

a single EQ channel.

Of course, if time and budget allow, individual EQ can be applied to each subwoofer before the

final EQ is applied to the single subwoofer channel, but this sophisticated approach requires

significant calibration time and multiple additional channels of DSP. We can recommend

experienced calibrators that are expert in tuning systems with multiple subwoofers.

While there is no upper limit of the number of subwoofers that can be used in a system (aside from

the obvious space and budget considerations), experience has shown that once there are four

subwoofer locations (two subwoofers in the screen wall would be considered as one location in this

case), the incremental benefit of additional subwoofers decreases quickly.

More details on the P15Si and P10Si can be seen in Appendix A at the end of this document.

18. P15AMP, P10AMP and P15A Amplifier and DSP Controls

The P15AMP, P10AMP and P15A active subwoofers have built-in DSP control to optimize

performance, based on speaker placement in the room.

Any loudspeaker’s response at low frequencies will be affected by its proximity to room surfaces.

Generally, as a speaker is moved closer a room surface such as a wall, ceiling or the floor, the total

low frequency energy produced by that speaker increases. This takes place due to acoustical

coupling effects and reinforcement by the room’s surfaces. Because the location of a speaker in any

given room cannot be predicted, Procella’s DSP control tunes the response of the speaker for

optimal performance under several room boundary conditions.

P15AMP and P10AMP Operation

Located on the control panel of the amplifier is a

button labeled Preset Select. Adjacent to the

button are four green LEDs, each labeled with a

number that identifies a preset. Preset 4 is at the

top and Preset 1 is at the bottom of the stack.

To change the preset, press the Preset Select

button located between the XLR jacks. Each press

of the button advances to the next numbered

preset. The active preset is identified by an

illuminated LED.

Presets

This chart identifies each preset and the installation condition for which each should be used. Each

press of the button advances to the next preset.

Preset Installation Condition

4 Free standing on the floor and away from all walls and corners.

3 Flush mounted in a loudspeaker baffle wall, where the front surface of the subwoofer should be flush with the surface of the baffle wall.

2 Positioned on the floor and against any wall (front, side, or back).

1 Positioned on the floor and in a corner.

Amplifier Level Control

The Gain control on the amplifier level sets the subwoofer level. The Default setting of “0” is

equivalent to –4 dB, and is at the 12 o’clock position. The Default position should be used when


60


calibrating the system. The minimum – ∞ position produces no output from the subwoofer, and

the maximum position is 6 dB greater than the Default “0” position.

Amplifier Temperature

It is normal for Procella amplifiers to be rather warm to the touch, even when the amplifier is

operating at low power levels. There is a warning LED that will blink if the amp reaches 80°C.

P15A Operation

The P15A amplifier is located on a recessed panel on the back baffle of the subwoofer. This allows

for input and power cable attachment even with the subwoofer set flush against the wall.

Either unbalanced RCA or balanced XLR input cables can be used with the P15A. An unbalanced

RCA output connector is provided for linking to additional subwoofers. When using the P15A with a

preamp or processor that has an unbalanced output, we recommend that a shielded 2-wire cable

with XLR connectors be used in combination with an RCA-XLR adapter at the preamplifier end. This

will produce the lowest noise level and best sound quality.

The Procella P15A is designed for use with a 4th order Linkwitz-Riley, low pass crossover at 80-125

Hz. The proper frequency depends on the main speakers used and the desired playback levels.

With the Procella P5/P5V/P5iW, use a frequency of 80 -120 Hz. For the Procella P6/P6V, Procella

P8, and larger speakers, the ‘THX’ or 80Hz setting in the processor will give the correct

characteristics.

Rear Panel Controls and Functions

The P15A controls and their functions are described below. See the back panel layout on page 61

for locations.

Gain

The Gain control sets the subwoofer output level. For reference, the default 0 dB reference is -4dB.

When setting subwoofer levels through a preamp or processor, the Gain control should be set to 0.

Polarity

The Polarity switch is used to match the polarity of the Procella P15A to the L/C/R speakers at the

listening position. This is important because of variables in the system such as the pre-amplifier,

crossover slopes and, especially, room position of both the main speakers and the subwoofer.

Without test equipment, you can perform a simple test that requires a listener seated at the main

listening position and a partner located at the subwoofer. Select and play through the full system a

music source with prominent mid-bass content. As it plays, the partner should flip the Polarity


61


switch when instructed to by the listener. The listener should listen carefully for changes in the

mid-bass level. The switch position that produces the greatest bass output is the correct setting.

Speaker Position

Optimizes response for room boundary

conditions at the location of the subwoofer. Use

the appropriate preset for the location in your

room.

WALL Positioned on the floor and against

a wall.

CORNER Positioned on the floor, against

a wall and close to a corner.

Power

ON Subwoofer fully ON.

AUTO Standby mode. Subwoofer switches

on when signal is present. The

STANDBY LED illuminates when in

STANDBY mode.

SET See Auto Setup below.

POWER There is also a Master Power switch

located on the input panel below.

Auto Setup

When selected, AUTO powers up the subwoofer only when a signal is present. Because it detects

the residual noise level of the preamp/processor, the circuit needs to be calibrated before use.

Once the input cable is connected between the subwoofer and the preamp/processor, do the

following. Set the power switch on the preamp/processor to ON (or out of Standby), with no source

playing. Then, on the subwoofer, move the switch to Set. The P15A STANDBY LED will start blinking

rapidly. When the LED blinking rate slows down, move the switch to AUTO.

You can confirm that you have the correct setting by playing any disc and verifying that the

STANDBY LED switches to Green when the material starts playing. If the LED turns green without

any source playing, check your installation and cable routing for AC mains or signal interference.

20. Cables and Connectors

Speaker Wire Connection

The following are our recommended minimums for loudspeaker cable used with Procella

loudspeakers. Feel free to use premium speaker cables per your preference, but we do not have

any specific recommendations for cable brands.

Cable run up to 25m (80’) AWG 14 (2.5mm²)

Cable run of 25 to 45m (80 – 150’) AWG 12 (4mm²)

Cable run of 45 to 75m (150-250’) AWG 10 (6mm²)

If you are planning to connect more than one surround speaker to a single amplifier channel with a

parallel connection, we recommend that separate speaker wires be run from each speaker to the

amplifier. This will provide maximum flexibility.

Active Speaker Connection

All active speakers with onboard amplifiers (P15AMP, P10 AMP, P15A) use balanced XLR inputs.

The P15A also provides unbalanced RCA inputs. The P15AMP has one male and one female XLR

connector to allow for a pass-through connection to another speaker. We strongly recommend the

use of balanced cables with Procella speakers because they produce minimum system noise and

maximum signal quality. When only unbalanced connections are possible, such as with A/V

receivers, an RCA to XLR adaptor is provided with each active speaker.

Also see AC and Grounding Requirements on page 66 for connection to components with

unbalanced outputs.

XLR Connector Wiring

Pin 1 = Ground

Pin 2 = Normal Polarity (Hot)

Pin 3 = Inverted Polarity (Cold)

Polarity

All Procella speakers have positive polarity. The red terminal is the positive (+) input, and a positive

voltage applied to it will produce a forward motion of the drivers.


66


21. AC and Grounding Requirements and Troubleshooting

The amplifiers in the P15AMP, P10AMP and P15A subwoofers have universal power supplies that

will operate to spec with any input voltage from 100V to 250V AC. The standard IEC three-prong

connection is used for the AC power cord.

All Procella amplifiers are High-Power, Switched-mode Class-D amplifiers. Like any digital amplifier,

proper mains, grounding and signal interconnections are essential for correct operation, to avoid

hum and buzz and to achieve the best possible signal to noise ratio.

Always follow these guidelines:

· Insure that the amplifier is connected to a properly grounded electrical outlet. A good and stable

ground connection is essential for correct operation of the switch-mode amplifier and the DSP.

· A proper ground connection is also essential to avoid electrical shock hazard.

· Procella Active Loudspeaker models utilize very high power amplifiers. Confirm that the power

line and circuits are dimensioned to handle the necessary load according to these guidelines:

Model: Recommended Minimum Load Rating

P15A 115V: 10A 230V: 6A

P15AMP and P10AMP 115V: 10A 230V: 6A

· The power line should be free from disturbances caused by other electrical appliances such as

motors, heaters and ovens, elevators, refrigerators or similar.

· All Procella active loudspeaker amplifiers have a professional balanced (XLR Female) input. For the

best possible performance, it is strongly recommended that the amplifier be connected with a

professional XLR-type, shielded 2-wire cable to a balanced output of the pre-amplifier.

· If the amplifier is connected to a pre-amplifier or

processor with an unbalanced output, use a n RCA-to-XLR

adaptor wired according to IEC 268-12 where pin 2 is

signal and pins 1 and 3 are connected to the shell. (e.g.

Neutrik NA2NMP) The adaptor should be connected at the

pre-amplifier end and the cable to the amplifier should be

a professional XLR-type, shielded 2-wire cable.

To minimize ground-loops in an unbalanced connection, connect the Procella active loudspeaker

amplifiers to the same outlet as the pre-amplifier or processor and run the signal cable in parallel

with the mains cable.


67


If hum or buzz is present in the system, despite following the above precautions, below are some

steps to solve the most common issues:

Confirm that all cables and connectors are in good shape and that there are no bad

connections.

If it is not possible to connect the Procella active loudspeaker amplifiers to the same wall

outlet as the pre-amplifier, try different wall outlets for the amplifier, preferably to an outlet

on a different circuit.

Modify the unbalanced to balanced adaptor (or make a separate adaptor) with a 10-100ohm

resistor in series with pin 1.

If nothing else helps, use a balancing isolation transformer such as:

o Lundahl Transformers model LL156X-PHF3MX

o Jensen Transformers model ISO-MAX SUB-XX


68


22. Bass Management and Surround Processor Settings

The P5/P5V/P5iW, P6/6V, P8 and P28 are designed for use with a Procella subwoofer, and should

be fed with a signal high-pass filtered by a surround processor or electronic crossover. The

recommended crossover is 80 Hz, and the correct slope is a second-order (12 dB/octave) Linkwitz-

Riley filter. The P5 can benefit from a higher crossover, up to 125 Hz for high power applications,

also with a second-order Linkwitz-Riley filter. This is the same crossover used for Home THX

processors or receivers, so if you are using a THX component, set the crossovers to the THX setting.

If there is no THX choice, use the SMALL speaker setting. If you the LARGE setting with any of these

speakers, no low frequencies for that channel will be directed to the subwoofer. There is no low-

pass filter in Procella active subwoofers, so the low-pass filter slope of the subwoofer crossover

should be fourth-order Linkwitz-Riley (24 dB/octave).

Full-range models

The P860, P815 and P610 meet cinema standards as a full-range speaker, with low-frequency

extension to 40 - 45 Hz. Because of this deeper bass extension, they can be operated as full-range

speakers (as in professional cinemas and dubbing stages), rather than using an 80 Hz crossover

point. Ideally, the P860, P815 and P610 can be set as FULL-RANGE (LARGE) speakers in the

processor, with the subwoofer handling only the LFE Low Frequency Effects channel. An

alternative, when possible, is to operate the LCRs full-range with the subwoofer low-pass filtered at

50 Hz or below.

Alternately, these full-range models can be bass managed to redirect bass to the subwoofer.

Typical settings are between 40 and 60 Hz, depending on room conditions. We recommend that

once the speakers are installed in the room, measurements and listening tests be conducted to

determine the best mode of operation, as there is great variation in rooms through this critical

frequency range. In some rooms, no bass management will be best, but in other rooms, bass

management will be necessary for smooth low frequency response.

Among the benefits of operating these as full range speakers is having the low frequencies

between 40 and 80 Hz produced by large drivers in three locations, which improves the soundfield

and uniformity of frequency response throughout the room. You will hear a more coherent and

impactful sound from the screen channels. Distortion is also lower in that range with more drivers

operating.

P15AMP, P10AMP and P15A Subwoofers

When calibrating subwoofer levels for the P15AMP and P15A subwoofers, the level control on the

subwoofer should first be set to the Default position, which is labeled as “0”. This represents a level

of –4 dB. Final levels can then be set using the controller or preamplifier. The minimum position on

the subwoofer level control produces no output from the subwoofer, and the maximum position is

6 dB greater than the Default “0” position.
