model for information and specifications.
NOTES
1. Loudspeaker system predictions for coverage and SPL are available in Meyer Sound's MAPP System Design Tool..
2. Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
3. Half-space loading, measured with 1/3 octave frequency resolution at 4 m.
4. Linear Peak SPL is measured in half-space at 4 m referred to 1 m. Loudspeaker SPL compression measured with M-noise
at the onset of limiting, 2-hour duration, and 50-degree C ambient temperature is < 2 dB.
NOTE: M-noise is a full bandwidth (10 Hz–22.5 kHz) test signal developed by Meyer Sound to better measure the loud-
speaker's music performance. It has a constant instantaneous peak level in octave bands, a crest factor that increases
with frequency, and a full bandwidth Peak to RMS ratio of 18 dB. Pink noise is a full bandwidth test signal with Peak
to RMS ratio 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 to verify there is still headroom over pink noise.
5. Peak power based on the maximum unclipped peak voltage the amplifier will produce into the nominal load impedance.
6. Tolerates voltage drops up to 30 percent due to long cable runs. Normal operating conditions with recommended cable
gauge, length, and number of loudspeakers assures peak SPL to remain within 2 dB of maximum SPL specification.
