- 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).
- Assembled in U.S.A. with U.S. steel and global components
The 1×2 T-bar ceiling 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.
