Architects’ and Engineers’ Specifications

Each loudspeaker shall be a 16 watt, ported loudspeaker utilizing one 2.25″ (57mm) full-range driver for installation on walls or other flat, solid surfaces.

The driver shall have a nominal rated impedance of 8 ohms and shall be wired in parallel with a line voltage matching (step-down) transformer with a level selector appropriate for various output taps. The loudspeaker input connections will allow for direct connection to 70 volt, 100 volt or low-impedance amplifiers.

Exposed cosmetic surfaces of the loudspeakers shall be paintable, and the acoustically transparent grille component shall be formed of powder-coated steel.

Each loudspeaker shall have a bandwidth of 95 Hz – 17 kHz and a maximum acoustic output of 96 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 four-pin, pre-wired connector.

Power settings available shall be: 1, 2, 4, 8, and 16 watts at 70 volts; 2, 4, 8, and 16 watts at 100 volts; and 16 watts at 8 ohms (when referenced to IEC noise for 100 hours). The nominal dispersion shall be 170° H x 160° V at -6 dB (average 1 – 4 kHz). When used with optional junction boxes, which include a ceramic connector and a thermal fuse, the loudspeakers shall meet numerous standards for combination music and evacuation systems around the world.

The loudspeakers shall be the Bose® FreeSpace® DS 16S and DS 16SE loudspeakers.
