Engineers’ and Architects’ Specifications
Each loudspeaker shall be a 40 watt, ported loudspeaker system utilizing one 4.5″ (114 mm) full-range HVC (Helical Voice Coil) driver. The loudspeaker shall be used for installation on walls, ceilings, and other flat, solid surfaces.
Each loudspeaker shall have a nominal rated impedance of 8 ohms and shall be wired in parallel with a line voltage matching (step-down) transformer with an accessible, front-mounted level selector appropriate for setting various output taps. The loudspeaker input connections will allow for direct connection to 70 volt, 100 volt or low-impedance amplifiers.
The loudspeaker shall have a protection circuit to protect the product from occasionally being overdriven.
Each loudspeaker shall have a bandwidth of 80 Hz – 17 kHz and a maximum continuous acoustic output of 103 dB SPL referenced to a full bandwidth pink noise input at 1 meter at the loudspeaker’s rated power. The input connection shall consist of a three-terminal barrier strip on the included mounting bracket. Each loudspeaker shall be wired to the mounting bracket via a 4- pin, pre-wired connector.
Power settings available shall be: 2.5, 5, 10, 20, and 40 watts at 70 volt; 5, 10, 20, and 40 watts at 100 volt; and 40 watts at 8 ohms (when referenced to IEC noise for 100 hours). The nominal dispersion shall be 125° H x 125° V coverage pattern at -6 dB (average 1 – 4 kHz).
When used with optional junction boxes (wall- mount bracket variant only), ceramic terminals and thermal fuse, the loudspeaker shall meet numerous standards for combination music and evacuation systems around the world.
Exposed cosmetic surfaces of the loudspeaker shall be paintable, and the acoustically transparent grille component shall be formed of powder-coated steel.
