Bose 102
Installation Speakers
From LSI January 1986
Unobtrusiveness is not a quality that normally distinguishes a PA speaker, but the new 102 range from Bose performs "with both accuracy and power" contained within a near-invisible enclosure, say the company. It is not a traditional ceiling speaker, but a carefully optimised 200-cubic inch flush-mounting acoustic enclosure specifically designed for unob- trusive installation or retrofitting. Compact, flexible, and easy to install it is able to offer a full bandwidth response at high sound pressure levels, with wide dispersion and high reliability. The system is designed for shops, hotels and any background applications, but it is also capable of handling a full-blown disco. The dual-port reflex design gives the best possible bass end. It includes a pre-wired 5-position level switch and factory-installed multi-tap transformer. Front and rear wiring access plates are provided and the whole unit requires only 3% in wall or ceiling depth. The Bose 102 (which comes in flush-mounting or surface mounting configurations) is available in a number of variants for 70 or 100 volt line operation at 8 or 25 watts, or 8 ohm, 25 watt, giving up to 101dBA SPL at 10 ft at 1 kHz. The frequency response is an impressive 80 H2-18 - / - 3dB. With identical performance specifications, the sound contractor can choose any combination of surface and flush mount Bose 102 enclosures, The third element in the 102 system is the System Controller, a unique unit offering two channels of music equalisation, allowing stereo or two-zone mono operation. The channels feature balanced differential inputs with sensitivity switches that can be set up for 100mv or 1 volt. The exclusive Optivoice circuitry in the System Controller automatically reduces the music level for voice overs, and then gradually restores it after the end of the message. Band-limiting equalisation and compression maximises voice-channel in- telligibility, giving a smooth and easily understood announcement quality. Overall, the Bose 102 is a commercial sound system that combines all the traditional Bose qualities of ruggedness, reliability, sound and power, with cost-effectiveness and ease of in- stallation, adding up to a system that is unique in the marketplace, say the manufacturers.
