Low frequency
Note: To eliminate interference at short wavelengths, the two 5" drivers work in combination at low frequencies below
320 Hz. Above 320 Hz only the cone driver closer to the tweeter is fed from the crossover up to the crossover frequency
to maintain optimal polar and off-axis frequency response characteristics.
High frequency
75 Hz - 20 kHz
Note: Recommended maximum operating frequency range.
Response depends on loading conditions and room acoustics.
80 Hz - 16 kHz ±4 dB
Note: Free field, measured with 1/3-octave frequency resolution at 4 meters.
300 Hz - 18 kHz ±60°
123 dB
Note: Measured with music at 1 meter.
>110 dB
100° x 100°
1.3 kHz
Note: At this frequency, the transducers produce equal sound pressure levels.
80 Hz - 20 kHz
Note: Recommended maximum operating frequency range. Response depends upon
loading conditions and room acoustics.
85 Hz - 19 kHz ±4 dB
Note: Measured with 1/3 octave frequency resolution at 4 meters.
300 Hz - 18 kHz ±60°
123 dB
Note: Measured with music at 1 meter.
>110 dB
45° x 45°
2.3 kHz
Note: At this frequency, the transducers produce equal sound pressure levels.
Two 5" cone drivers
Nominal impedance: 8 Ω
Voice coil size: 1"
Power-handling capability: 200 W (AES)
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.

Nominal impedance: 8 Ω
Voice coil size: 1"
Diaphragm size: 1"
Power-handling capability: 20 W (AES)
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.
