    DTH 215bLow-Frequency


  • DESCRIPTIONThe DTH 215b is a perfect matchas an additional low-frequencyenclosure for any of the DTH

    enclosures. This enclosure isloaded with two 1505-8DT BlackWidow drivers. One of thesewoofers has been mounted back-wards (its electrical polarity has alsobeen reversed so that its acousticalpolarity is identical tothe other woofer). The anti-axialarrangement of the driverseliminates virtually all even-orderharmonic distortion. Maximumversatility was our main goalwhen considering the input tothis loudspeaker. Both drivers areconnected to a Neutrik four-conductor Speakon connector.The drivers are also connected toone half of a Neutrik eight-conductor Speakon connector.The other half of this connector ishooked up to a second Neutrik

    four-conductor connector. Thisconnector serves as an output toanother loudspeaker such as aDTH 215b. By using this output,you will have only one home runof a cable going to your ampsinstead of two four-conductorcables. A black polyurethanecoating covers the DTH 215b. Aheavy-duty, 16-gauge metal grillewith polyester foam overlay dressesoff the enclosure and provides

    superior protection for the drivers.All this combines to give you agreat-looking and great-soundingsubwoofer perfectly suited to anylow-frequency sound reinforcementapplication.

    FREQUENCY RESPONSEThis measurement is useful indetermining how accurately a givenenclosure reproduces an inputsignal. The frequency response ofthe DTH 215b is measured at 1meter using a 2.0-volt swept sineinput. As shown in Figure 1, thedrivers in the DTH 215b combine togive a smooth frequency responsefrom 45 Hz to 250 Hz.

    POWER HANDLINGThere are many differentapproaches to power handlingratings. Peavey rates this speakersystem's power handling using amodified form of the AES Standard2-1984. Utilizing audio band(20 Hz to 20 kHz) pink noise withpeaks over four times the RMSlevel, this strenuous test signalassures the user that every portionof this system can withstand todayshigh-technology music. The testsignal contains large amounts ofvery low frequency energy,effectively simulating the frequencycontent of live music situations. Thefull measure of high frequencies in

    the test signal allow for exposure ofthe speaker system to synthesizedtones that may extend beyondaudibility. This rating is contingenton having a minimum 3 dB ofamplifier headroom available.

    ARCHITECTURALAND ENGINEERINGSPECIFICATIONSThe loudspeaker system shall havean operating bandwidth of 45 Hz to250 Hz. The output level shall be100 dB when measured at adistance of one meter with an inputof one watt. The nominal imped-ance shall be 4-ohms with speakersparalleled, 8-ohms with speakersindependently powered. Thecontinuous power handling shallbe 700 watts, with maximumprogram power of 1400 watts andminimum amplifier headroom of3 dB with speakers paralleled. Thecontinuous power handling shallbe 350 watts x 2, with maximumprogram power of 700 watts x 2,and minimum amplifier head-room of 3 dB with speakersindependently powered. Theoutside dimensions shall be18-3/4 inches wide by 39-3/4 incheshigh by 30-3/4 inches deep. Theweight shall be 123 lbs. Theloudspeaker system shall be aPeavey model DTH 215b.

    DESCRIPCINEl altavoz DTH 215b resultaperfecto como gabinete adicionalde baja frecuencia para cualquierade los gabinetes DTH. Estegabinete est provisto de dosaltavoces de graves Black Widow

    1505-8 DT. Uno de estos altavocesde graves est montado hacia atrs(su polaridad elctrica tambin estinvertida, de manera que lapolaridad acstica es idntica a ladel otro altavoz). La disposicinantiaxial de los altavocesprcticamente elimina todadistorsin armnica de orden par.Cuando se consideraron lascaractersticas de la seal deentrada de este altavoz, el principalobjetivo fue lograr mximaversatilidad. Ambos altavoces se

    hallan conectados a un conectorNeutrik Speakon de cuatroconductores. Tambin estnconectados a la mitad de unconector Neutrik Speakon deocho conductores. La otra mitad deeste conector est unido a unsegundo conector Neutrik decuatro conductores, que se utilizacomo salida para otro altavoz,como el DTH 215b. Empleandoesta salida, se requerir un solocable de salida de amplificadoresen lugar de dos cables de cuatroconductores. El modeloDTH 215b est terminadocon poliuretano negro. Unagrilla metlica resistente de chapacalibre 16 y un acolchado deespuma de polister negrocompletan la envoltura delgabinete, y proveen una proteccinexcelente para los altavoces. Todoesto se combina para brindar unaltavoz subsnico de magnficaapariencia y gran sonido,perfecto para cualquier aplicacinde refuerzo de sonidos de bajafrecuencia.
