• 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. Maximum SPL is the peak measured in free-field at 4 m referred to 1 m using noise.
  • 4. 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-hour duration, and 50-degree C ambient temperature is <2 dB. M-noise is a full bandwidth, (10Hz–22.5kHz) 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 bandwidth Peak to RMS ratio of 18 dB. Pinknoise 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. AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not cause the loudspeaker’s voltage to drop below the specified operating range.
