APPENDIX A: SPECIFICATIONS
MM-4XP SPECIFICATIONS
Operating Frequency Range 120 Hz – 18 kHz
Note: Recommended maximum operating frequency range. Response depends on loading conditions and
room acoustics.
Frequency Response 160 Hz – 16 kHz ±4 dB
Note: Measured free-field with pink noise at 1 meter, 1/3rd octave resolution.
Maximum Peak SPL 113 dB
Note: Measured free-field with music and referred to 1 meter.
Dynamic Range 100 dB
Note: Taken from peak SPL referred to A-wtd noise floor.
Phase Response 700 Hz – 17 kHz ±45°
Coverage 80° (3 kHz – 14 kHz ±10°); 120° (below 2 kHz)
Transducer One 4” cone driver
Voltage Requirement 48 V DC
Audio/Power Connector Single EN3 5-pin male (3 pins for balanced audio, 2 pins for DC power)
Input Impedance 10 kΩ electronically balanced
Nominal Input Sensitivity –2.5 dBV (0.75 V rms, 1.0 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 Ω to produce maxi-
mum peak SPL over the operating bandwidth of the loudspeaker
Current Draw 0.7 A average; 2.2 A peak
LED To indicate loudspeaker status
