Bose Model 32 Ceiling Speaker 1 pair

Loudspeaker Configuration The 100 Volt version can be part of a distributed sound system when used in conjunction with the FreeSpace® controller and a comparable amplifier. The 4 Ω model is intended to be a budget loudspeaker requiring neither tap capability, line amplifier, nor equalizer. Any modest amplifier or receiver can be used to drive this loudspeaker. It utilises a mid-band RLC filter to equalise driver output. Engineers’ and Architects’ Specifications The loudspeaker shall be a 32 Watt ported loudspeaker system utilising one 4.5″ (11.4 cm) full-range driver for installation in a manner where the grille surface is nominally flush with the ceiling surface and the enclosed volume protrudes within the ceiling space. The 100 V version shall be designed for use with a proprietary active equalization device. Versions intended for use with line amplifiers shall also contain multiple tap impedance matching transformers. The design shall minimise the use of organic materials in the product and the mounting mechanism such that the product shall meet the requirements of U.L. 2043. All exposed cosmetic surfaces shall be paintable and the acoustically transparent grille component shall be formed of expanded metal mesh. A dust and paint shield shall be supplied with every unit to protect the transducer prior to grille installation. The loudspeaker’s maximum acoustic output shall be 104 dB-SPL from 80 Hz – 16 kHz, with measurements referenced to a fullbandwidth pink noise input at 1 meter at the loudspeaker’s rated power. The input connection shall consist of a barrier strip screw-type terminal. Its power handling capability shall be 1 W, 2 W, 4 W, 8 W, 16 W, or 32W continuous power when referenced to IEC noise for 100 hours. The nominalcoverage angle shall be 132° conical. The loudspeaker shall be the BOSE® FreeSpace® Model 32 flush-mount loudspeaker.
