Note: The driver is coupled to a 100-degree-horizontal constant-directivity horn through a proprietary acoustical
combining manifold (REM).
70 Hz - 18 kHz
Note: Recommended maximum operating frequency range. Response depends upon
loading conditions and room acoustics.
76 Hz - 16 kHz ±4 dB
Note: Measured free field with 1/3-octave frequency resolution at 4 meters.
1.5 kHz - 16 kHz ±30°
131 dB
Note: Free field, measured with music referred to 1 meter.
>110 dB
100°
Varies, depending on array length and configuration
1100 Hz
Note: At this frequency, the transducers produce equal sound pressure levels.
Two 8" cone drivers with neodymium magnets
Nominal impedance: 4 Ω
Voice coil size: 1.5"
Power handling capability: 600 W (AES); 900 W peak
Note: Power handling is measured under AES standard conditions: both transducers driven
continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
Peak power handling is measured with both transducers driven for 100 milliseconds with
pink noise signal having a 12 dB peak-average ratio.
Note: To eliminate interference at shorter wavelengths, the two 8-inch drivers work in
combination at lower frequencies (70 Hz - 320 Hz). At mid frequencies (320 Hz - 1100 Hz)
only one cone driver is active to maintain optimal polar and frequency response
characteristics.
3" compression driver
Nominal impedance: 8 Ω
Voice coil size: 3"
Diaphragm size: 3"
Exit size: 1.2"
Power handling capability: 180 W (AES); 360 W peak
Note: Power handling is measured under AES standard conditions: transducer driven
continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
Peak power handling is measured with transducer driven for 100 milliseconds with
pink noise signal having a 12 dB peak-average ratio.
