Specifications

ACOUSTICAL
Operating frequency range	30 Hz – 125 Hz
Maximum linear sound levels	125.5 dBZ, 135.3 dBZpk, with an RMS analog input level of +3.1 dBV, digital -21dBFS, half space
Linear Sound Levels are measured in half-space at 4 m with a Class 1 sound level meter in accordance with IEC 61672 and ANSI S1.4. Values are scaled to 1 m distance from the loudspeaker while the loudspeaker is reproducing the AES75 test signal for at least one hour when the ambient temperature is 113 F° (45 C°). Loudspeaker system predictions for coverage and SPL are available in Meyer Sound’s MAPP System Design Tool.
