Architects’ and Engineers’ Specifications

The loudspeaker shall be a ported loudspeaker system utilizing one 4.5″ (114 mm) HVC environmental full-range driver mounted in the underside of the top of the loudspeaker enclosure. The driver shall have a rated impedance of 4 Ω and shall be wired in parallel with a line voltage-matching (stepdown) transformer with taps at 10, 20, 40, or 80 watts.

The loudspeaker shall have a single-port vented system, with a maximum continuous acoustic output of 100 dB SPL from 70 Hz to 10 kHz, with measurements referenced with full-bandwidth pink noise at 1 meter at the loudspeaker’s rated power.

The input connection shall consist of wires with wire nuts on a cable attached to the base of the loudspeaker. The nominal dispersion of the loudspeaker shall be 360° horizontal and 50° vertical.

The loudspeaker shall be the Bose® FreeSpace® 360P Series II loudspeaker.
