Architectural Specifications
The loudspeaker shall be a self-powered, sub-bass system. The transducer shall consist of one 15-inch long excursion cone driver. The loudspeaker shall incorporate a 2-channel, open-loop, class D amplifier.
Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: operating frequency range shall be 22–160 Hz; frequency response shall be 25–145 Hz ±4 dB; phase response shall be 33–145 Hz ±30°; linear peak SPL shall be 124.5 dB with >11.5 dB crest factor, measured in half-space with M-noise at 4 m referred to 1 m.
The loudspeaker shall be equipped standard with an XLR 3-pin looping input panel. Optionally, the loudspeaker could be equipped with an XLR multiple 3-pin connector integration module to create a 2.1 system or a DB-25 multi-pin connector module to create a 7.1 immersive system. The audio input shall be differential and electronically balanced with 10 kΩ impedance, and a continuous 6 dBV (2 V rms) input signal shall typically drive the speaker to the onset of limiting for noise and music.
Power requirements for the loudspeaker shall be 100–240 V AC, 50–60 Hz. Maximum long-term continuous current draw for the loudspeaker (> 10 sec) shall be 1.4 A rms (115 V AC); 0.7 A rms (230 V AC); 1.5 A rms (100 V AC). The power supply shall provide automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.
All components shall be mounted in an acoustically vented, box-shaped enclosure constructed of premium multi-ply birch with a slightly textured black finish. Left and right sides shall incorporate 3/8-inch by 16 threads. The front protective grille shall be powder-coated, hex-stamped steel.
Dimensions for the loudspeaker shall be W: 24.00 in (609 mm) x H: 17.5 in (444 mm) x D: 19.00 in (482 mm) without mounting bracket. Weight shall be 74 lb (33.5 kg).
The loudspeaker shall be the Meyer Sound Amie-Sub.
