Operating Frequency Range

66 Hz – 18 kHz
Note: Recommended maximum operating frequency range. Response depends on loading condi-
tions and room acoustics.

Frequency Response

72 Hz – 17.5 kHz ±4 dB
Note: Measured free-field with pink noise at 1 meter, 1/3rd octave resolution.

Maximum Peak SPL

121 dB
Note: Measured free-field with music, referred to 1 meter.

Dynamic Range

> 105 dB
Note: Taken from peak SPL, referred to A-wtd noise floor.

Phase Response

360 Hz – 12 kHz ±45°

Coverage

100° symmetrical

Acoustical Crossover

1.5 kHz
Note: At this frequency, the transducers produce equal sound pressure levels.

Input Impedance

10 k

 differential between pins 4 (–) and 5 (+)

DC Blocking

Differential DC blocking up to the maximum common mode voltage

CMRR

>50 dB, typically 80 dB (50 Hz – 500 Hz)

RF Filter

Common mode: 425 kHz



Differential mode: 142 kHz

TIM Filter

<80 kHz, integral to signal processing

Nominal Input Sensitivity

–2.0 dBV (0.80 V rms, 1.12 V peak) continuous average is typically the onset of limiting for noise 
and music

Input Level

Audio source must be capable of producing +16 dBV (6.3 V rms, 9.0 V peak) into 600 

to produce 

the maximum peak SPL over the operating bandwidth of the loudspeaker

Amplifier Type

Three-channel (class D)
