Bose 802 Series II Loudspeaker ® ® General Description The Bose 802 Series II sound components provide a fully modular system designed for high quality reinforcement of voice and music. Bose 802 Series II loudspeakers work with the 802C Series II systems controller for active equalization of the system. The 802 Series II loudspeaker is preferred for applications requiring a rugged, portable enclosure, but can be used in permanent indoor sound system installations. • Modular components for system design flexibility • High linear excursion and power output • Electronic systems controller Component Description Technical Information Frequency range 55Hz – 16kHz Vertical beamwidth 100° Active equalization (with 802C Series II systems controller) Required Enclosure construction Mica-reinforced polyethylene copolymer structural foam Nominal impedance 8Ω Fusing Built-in 4-ampere quick-acting fuse (replaceable) Maximum acoustic output 114dB-SPL average, 123dB-SPL peak Power handling capacity 240W continuous pink noise, 55Hz – 16kHz Recommended amplifier power 240W minimum, 480W maximum Sensitivity Full-range, 91dB-SPL (1W, 1m) Horizontal beamwidth 120° The 802C Series II systems controller assures smooth, accurate spectral response across the entire operating range of the 802 Series II loudspeaker. Sharp subsonic and ultrasonic band-limiting filters reduce power waste, stage noise, high-frequency instability, and interference. The systems controller also provides two independent signal channels. Insert locations Four M8 (8 mm) Connectors Two (2) parallel-wired 1⁄4" (6.3 mm) phone jacks and two (2) parallel-wired male XLR connectors Dimensions 13" (H) x 201⁄2" (W) x 121⁄2" (D) (33 x 52 x 32 cm) Weight 31 lb (14 kg) Each 802 Series II loudspeaker uses eight 41⁄2" full-range drivers mounted in symmetric vertical pairs on a faceted Articulated Array baffle assembly. The drivers feature low-impedance, edge-wound aluminum voice coils, 12-ounce Ferrite V ceramic magnets, and molded polyester frames. Their advanced cone and motor system give them high linear excursion capability and power output. ® Tuned reactive air columns reduce distortion by controlling the cone excursion required to reproduce deep bass frequencies. A built-in directivity control circuit maintains the vertical dispersion pattern through the high-frequency range. It also protects the drivers from high-frequency overload. The 802C Series II systems controller is a single-rack sized device. It is capable of providing crossover functions, active electronic equalization, and dual channel signal processing for both the 802 Series II loudspeakers and the 502 B or 502BP Acoustimass enclosure. It features -10/+4dB-V input sensitivity switches, all-balanced inputs and outputs, -18/+3dB bass level control, and a bass mono sum switch. It also provides automatic output muting on turn-off, and a secure rear-panel operating mode switch. ® ® REFER TO YOUR INSTRUCTION MANUAL FOR PROPER INSTALLATION AND OPERATING PROCEDURES.
