HMS-15
The loudspeaker shall be a self-powered, full-range system with an onboard 2-channel amplifier and internal processing that shall include equalization, phase correction, signal division, and driver protection. Transducers shall include one 15-inch long-excursion cone driver and one 3-inch diaphragm compression driver. The crossover point shall be 680 Hz.
Performance specifications, measured at 1/3-octave resolution, for a typical production unit shall be: operating frequency range, 50 Hz to 18 kHz; phase response, 290 Hz – 18 kHz ±45 degrees; linear peak SPL, measured with pink noise, 128.5 dB at 1 meter, free field. Coverage shall be 80-degree horizontal by 50-degree vertical.
The loudspeaker shall be equipped with dual Phoenix 5-pin male connectors (two pins for DC power and three pins for balanced audio). Power requirements for the loudspeaker shall be a Meyer Sound MPS‑488HP IntelligentDC power supply.
Components shall be mounted in a multi-ply hardwood enclosure with a black textured finish. The cabinet shall include rear and side attachment points for optional mounting. The grille shall be an acoustically transparent, detachable, black cloth-covered frame. Dimensions for the loudspeaker shall be 19.00 inches wide x 29.10 inches high x 12.50 inches deep (483 mm x 739 mm x 318 mm) without mounting bracket. Weight shall be 60 lbs (27.2 kg).
