750-LFC Very Compact Low-Frequency Control Element

The loudspeaker shall be a compact, self-powered, linear, low-distortion, low-frequency control element and shall be capable of flown,

ground-stacked, and cardioid configurations. Its transducer shall be one 15 in dual-coil long-excursion cone driver with 2 Ω nominal impedance.

The loudspeaker shall incorporate internal processing and a 2-channel, open-loop, class D amplifier. Processing shall include equalization, phase correction, and driver protection. Performance specifications for a typical production unit shall be as follows: operating frequency range shall be 35–125 Hz; frequency range shall be 37–110 Hz ±4 dB (measured in half-space with pink noise at 4 m, 1/3-octave frequency resolution); phase response shall be 43 Hz–110 Hz ±30°; linear peak SPL shall be 130.5 dB, measured in half-space with M-noise at 4 m referred to 1 m.

Audio connectors shall be XLR 3-pin, female with male loop, accommodating balanced audio, or XLR 5-pin, accommodating both balanced audio and RMS.

The internal power supply shall perform EMI filtering, soft current turn-on, and surge suppression. Power requirements shall be nominal 100, 110, or 230 V AC line current at 50–60 Hz. UL and CE operating voltage range shall be 100–240 V AC at 50–60 Hz. AC power connectors for input and loop output shall be powerCON 20.

Maximum long-term continuous current draw shall be 5.3 A rms at 115 V AC, 2.7 A rms at 230 V AC, and 6.2 A rms at 100 V AC.

The loudspeaker shall accommodate an optional RMS remote monitoring system module.

Components shall be mounted in an optimally tuned, vented enclosure constructed of premium multi-ply birch with a slightly textured black finish. Optional rigging for the enclosure shall include end frames with captive GuideALinks for linking units in vertical arrays with 0°, 1.5°, 3.25°, or 4.75° splay angles. The front protective grille shall be powder-coated, hex-stamped steel with acoustical black mesh.

Dimensions shall be 21.80 inches (554 mm) wide x 20.30 inches (515 mm) high x 20.88 inches (530 mm) deep. Dimensions with optional rigging shall be 21.55 inches (547 mm) wide x 20.43 inches (519 mm) high x 20.88 inches (530 mm) deep. Weight shall be 89 lbs (40.3 kg). Weight with optional rigging shall be 105 lbs (47.6 kg). 

The loudspeaker shall be the Meyer Sound 750-LFC
