SPECIFICATIONS
ACOUSTICAL
Operating Frequency
Range
100 Hz – 16 kHz
Note: Recommended maximum operating frequency range. Response depends on loading conditions and
room acoustics.
Frequency Response 105 Hz – 15 kHz ±4 dB
Note: Measured free field with 1/3-octave frequency resolution at 4 meters.
Phase Response 230 Hz – 16.9 kHz ±45°
Linear Peak SPL CAL 96
(295 ft or 90 m)
CAL 64
(196 ft or 60 m)
CAL 32
(98 ft or 30 m)
101 dB peak with 18.5 dB crest factor (M-Noise), 98 dB (Pink Noise), 100 dB (B-Noise)
Note: CAL set to single beam, 5° vertical spread, and no steering.
Linear Peak SPL is measured in free-field at 4 m, referred to 1 m.
Loudspeaker SPL compression (measured with M-Noise at the onset of limiting, 2-hr
duration, and 50°C ambient temperature) is <2 dB.
M-noise is a full bandwidth (10 Hz to 22.5 kHz) test signal developed by Meyer Sound to
better measure the loudspeaker’s music performance. It has a constant instantaneous
peak level in octave bands, a crest factor that increases with frequency, and a full band-
width Peak-to-RMS ratio of 18 dB.
Pink noise is a full bandwidth test signal with a Peak-to-RMS of 12.5 dB.
B-noise is a Meyer Sound test signal used to ensure measurements reflect system
behavior when reproducing the most common input spectrum, and verify there is still
headroom over pink noise.
