Acoustical crossover
TRANSDUCERS
Low/low-mid frequency
Note: To eliminate interference at short wavelengths, the two 12-inch drivers work in combination at low frequencies (60
Hz – 180 Hz). At mid frequencies (180 Hz – 560 Hz) only one cone driver is fed from the crossover to maintain optimal
polar and frequency response characteristics.
Mid-high frequency
Note: The driver is coupled to a constant-directivity horn through a proprietary acoustical combining manifold (REM).
Very-high frequency
Note: The two drivers are coupled to a constant-directivity horn through a proprietary acoustical combining manifold
(REM).
60 Hz - 18 kHz
Note: Recommended maximum operating frequency range. Response depends upon
loading conditions and room acoustics.
65 Hz - 17.5 kHz ±4 dB
Note: Measured with 1/3-octave frequency resolution at 4 meters.
750 Hz - 16 kHz ±30°
138 dB
Note: Measured with music at 1 meter.
>110 dB
120°
Varies, depending on array length and configuration; for single loudspeaker, 20°
560 Hz, 4.2 kHz
Note: At these frequencies, the transducers produce equal sound pressure levels: 560 Hz
for the low-mid and mid-high and 4.2 kHz for the mid-high and very-high frequency drivers.
Two 12" cone drivers with neodymium magnets

continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
One 4" compression driver
Nominal impedance: 8 Ω
Voice coil size: 4"
Diaphragm size: 4"
Exit size: 1.5"
Power handling capability: 250 W (AES) on REM
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.
Two 2" compression drivers
Nominal impedance: 12 Ω
Voice coil size: 2"
Diaphragm size: 2"
Exit size: 0.75"
Power handling capability: 100 W (AES) on REM
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.
