Quick install speaker for suspended tile ceilings features 8 in. 20W coaxial driver, 70V transformer, fine perforation grille, and .147 cu.ft. enclosure. Patented 1×2 assembly with integral T-bar quickly replaces half a non-tegular (2×2) ceiling tile. U.S. patents 7120269, D467579, 7643647.
-Driver (CT830A): 8 in. 20W coaxial driver with 12 oz. magnet, frequency response of 57Hz-14kHz (±6dB) and 44Hz-20kHz (±7.6dB), average sensitivity of 97.0dB measured 1W/1M, and 80 degrees conical dispersion.
-Transformer (TLM-870): 70V with taps at 1, 2, 4, 8W
-Enclosure (8XD4): .147 cu.ft. steel backbox with speaker leads that exit through a metal clamp for fast connection. Black.
-Grille with Subplate (1 x 2): Fine-perforation grille provides maximum free-air space for excellent sound transmission while maintaining an unobtrusive appearance in new or existing tile ceilings. White.
-Mounting Aids: Patented integral T-bar to support neighboring non-tegular ceiling tile. Restraint tab and hole for two-cable code compliance (cables not included).
The speaker system for suspended tile ceilings shall be Lowell Model No. LT-830-870-BB. The 1’x2′ system shall replace half of a non-tegular 2’x2′ ceiling tile or one-fourth of a non-tegular 2’x4′ ceiling tile and shall include an integral T-bar to support adjacent ceiling tile. Each speaker system shall include a factory-mounted driver mounted to a sub-plate with a fine perforation steel grille finished in white powder epoxy. The driver shall be 8 in. coaxial with a power rating of 20W. It’shall have a magnet weight of 12 ozs., frequency response of 57Hz-14kHz (±6dB) and 44Hz-20kHz (±7.6dB), and average sensitivity of 97.0dB measured 1W/1M. The mounted transformer shall be 70V with primary taps at 1, 2, 4 and 8W. The system shall include a steel backbox (.147 cu.ft.) with leads exiting through a metal clamp.
