Frequency Range: | 32 - 1500 Hertz |
| 28 - 3300 Hertz useable range |
Nominal Coverage: | 100° horizontal X 55° vertical at 600 Hertz |
Maximum Output: | 132.5 dB SPL calculated peak, 1 meter, half space, at rated rms power with 6 dB crest factor pink noise input, 25 - 250 Hertz. |
| 126.5 dBA SPL calculated maximum continuous, 1 meter. The dBA scale is typically used to identify sound sources |
| which can cause permanent hearing loss. |

Sensitivity: | 98.5 dB half space, 97.5 dB full space, 35 - 1000 Hertz, 1 watt, 1 meter |
Recommended Processing: | Subsonic filter below 30 Hertz, >18 dB per octave, maximum recommended crossover frequency is 1000 Hertz. QSC |
| DSP configurations are available at www.qscaudio.com. Parameters for alternative processing hardware are available |
| upon request. |
Connectors: | Barrier strip screw terminals accept up to #10 AWG stranded wire. Four terminals: (two INPUT and two PARALLEL |
| OUT). Transducers are internally wired in parallel. For independent transducer connection, remove blue jumper wire |
| and yellow jumper wire on |
Transducers: | Two 15” (381mm) high efficiency low frequency transducers featuring vented 3” (76mm) copper voice coils on Kapton® |
| formers. High excursion/low distortion design, with extremely high power handling, and low thermal and port com- |
| pression. |
