Meyer Sound CQ-1 Speaker Rental

Wide Coverage Main Loudspeaker


This self-powered, phase-corrected reinforcement loudspeaker for rental hire in Orlando offers precise, low-Q coverage. Frequency response of 40 Hz to 16 kHz is uniform over the entire coverage area in both the horizontal and vertical axes, with no side lobes even when measured at a one-sixth octave frequency resolution.

The CQ-1 loudspeaker’s unique combination of precise pattern control, compact size, low distortion and high power make it ideal for a wide variety of rental applications. It can be used as the main PA in small- to mid-sized auditoriums, houses of worship, clubs, and hotel ballroom settings, and is highly effective in delayed fill applications for arenas and outdoor concert systems.

Rigging: Aircraft pan fittings, two on both top and bottom. Working load for each fitting is 500 lbs, which is 1/5 the cabinet breaking strength (with straight tensile pull).

RMS Network (optional): Equipped for two conductor twisted-pair network, reporting amplifier operating parameters to system operator’s host computer.

1. Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
2. Free field, measured with 1/3-octave frequency resolution at 4 meters.
3. Measured with music at 1 meter.
4. At this frequency, the low- and high-frequency transducers produce equal sound pressure levels.
5. Power handling is measured under AES standard conditions: transducer driven continuously for two hours with band-limited noise signal having a 6 dB peak-average ratio.
6. Amplifier wattage rating is based on the maximum unclipped burst sine-wave rms voltage the amplifier will produce into the nominal load impedance. Both channels 70 V rms (100 V pk) into 8 ohms.
