DIGITAL POWER AMPLIFIERS KDA
Backed by FBT’s strong
leading experience in poly-
propylene moulded speaker
enclosure manufacturing,
Kempton’s New GT Series of
Active and Passive portable
speaker systems express ori-
ginal enclosure design and
engineering to offer an ama-
zing blend of user-friendly fea-
tures along with quality sound
reproduction. These eye-cat-
ching and affordable enclosu-
res with quality components
provide usage in a wide range
of applications. The Kempton
GT Series speakers feature
selected custom designed
woofers, and compression dri-
vers that are coupled to an
80°H x 50°V constant directi-
vity horn. The GT 12 A powe-
red version, with its Class AB
bi-amped power module offers
easy-access to the controls
and connectors.
Cabinet EnclosuresKempton’s GT Series injected moulded polypropyle-
ne enclosures feature an original proprietary cabi-
net design with smooth and flowing lines that imme-
diately identifies the GT series appearance from the
many Competitors models that look very much the
same. The GT Series enclosures rugged construc-
tion and exterior finish were designed to handle the
rigors of the road when used for portable sound
reinforcement applications.
ShapeThe Asymmetrical trapezoidal shape design provides
a 45° taper angle for stage monitoring applications
as well as for a general Front of House P.A. system
Pole Mount Sockets & HandlesFor speaker stand mounting all GTs are equipped
with a 35mm Ø (13/8”) aluminium pole mount socket.
The GT Series models feature ergonomically placed
carrying handles for a balanced “feel” when handling
/ transporting.
GrillesExtremely rugged 1.2mm (0.05”) steel grilles pro-
tect the woofer without detracting from its sonic
performance in any way.
Rigging/Fly points & Stacking capabilitiesAll GT enclosures are provided with multiple M10 fly
points to accept standard M 10 eye-bolts to facili-
tate safe and easy flying capabilities. The enclosures
are equipped with rubber feet and stacking posi-
tions that are moulded into the cabinet enclosures,
allowing stable stacking of 2 cabinet enclosures.
Power Amplifier (GT12A)The bi-amplification system of the GT12A consists
of two independent Class AB amplifiers, one for the
LF woofer and one for the HF compression dri-
ver/horn. Independent LF & HF Thermal and short-
circuit protection circuits are also featured. The
Crossover circuitry features an active electronic
24dB/oct Linkwitz-Riley design. The innovative 2-
channel on-board mixer (CH A and CH B) with each
one featuring: Preamp Gain, Volume, High Frequency
EQ, Low Frequency EQ controls, XLR/Jack combo
inputs. An XLR-M output jack provides mixed signal
output of input channels A and B.
Passive Version (GT12)The GT12 Passive speaker features professional
2 x 4-pin Speakon connectors mounted to a reces-
sed panel to prevent inadvertent operation.
ComponentsAll components were carefully selected and manu-
factured to Kempton’s specifications and tolerances
and then severely tested for reliability for the
Kempton GT Speaker series. The custom designed
Woofers feature high strength curvilinear cones on
steel chassis ferrite frames, high temperature resi-
stant voice coils to prevent burnout failures and fer-
rite magnet structures to produce solid low fre-
quency response. The HF compression drivers pro-
vide clean and clear high frequency output and are
coupled to an 80°H x 50°V custom designed con-
stant directivity horn for precise dispersion.
Crossover NetworksThe Heavy Duty Crossover Networks that divide the
signal going to the woofer and compression driver
are constructed with oversize coils, high voltage
capacitors and power resistors to provide the best
possible sound quality and minimize signal loss.
Independent LF and HF overload protection circuits
are employed to protect the woofers and HF drivers
from failures.

Kempton’s PW Series
speaker enclosures are
the perfect compliment for
high power live sound and per-
manent installation applica-
tions. Featuring quality
custom designed woofers, and
quality compression drivers
that are coupled to a constant
directivity 80°H x 50°V horn in
plywood enclosures. The acou-
stically contoured crossover
network provides full protec-
tion for both LF woofers and
HF drivers.
Cabinet Enclosures15mm, (5/8”) plywood is used in the construction of
cabinet enclosures on all models except for PW
218 which has 18mm (3/4”) cabinet enclosure. The
use of solid glue joints and the critical placement
of internal bracing results in enclosures that vir-
tually indestructible as well as resonance-free.
Shape: Maximum VersatilityThe Asymmetrical trapezoidal design shape with a
45° angle provides for Stage Monitor use and
Front of House applications (PW10-PW12-PW15).
FinishDurable textured black paint is used to withstand
to the rigors of the road when transporting and
provide a stylish appearance for permanent instal-
lations.
Pole Mount Sockets & HandlesFor speaker stand
mounting, all PW
models are equipped
with a 35mm Ø (13/8”)
aluminium pole mount
socket. Ergonomically
placed integrated
handles are built into
the 100% plywood
structure of the cabi-
net enclosure.
Heavy Duty Grilles An extremely rugged
1.2mm (0.05”) steel
grille with high apertu-
re ratio protects the
speakers without
detracting from their
sonic performance in
any way.
Rigging / Fly PointsAll Kempton PW enclo-
sures are provided with
multiple M10 fly points (M6 on PW10) to accept
standard eye bolts and facilitate safe and easy
flying capabilities.
ConnectorsAll Kempton PW model Speakers feature profes-
sional 2 x 4-pin Speakon connectors that are
mounted to a recessed panel to prevent inadver-
tent operation.
