- Driver (JR410): 4 in. 15W high-compliance driver with 10 oz. magnet. Frequency response of 67Hz-16kHz (±6dB) and 53Hz-20kHz (±8dB). Average sensitivity of 90.8dB measured 1W/1M. Conical dispersion 170 degrees.
- Transformer (TLM-572): Dual voltage 25V/70V transformer with primary taps at .25, .5, 1, 2, 5W
- Enclosure (8XD4): 0.147 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 white 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 supports neighboring non-tegular ceiling tile. A hole in one corner and restraint tab diagonally opposite allow (two cable) code compliance (cables not included).
- Assembled in U.S.A. with U.S. steel and global components
The drop ceiling speaker for suspended tile ceilings shall be Lowell Model LT-410-72-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 subplate with a fine perforation steel grille finished in white powder epoxy. The driver shall be 4 inches with a power rating of 15W. It shall have a magnet weight of 10 ozs., frequency response of 67Hz-16kHz (±6dB) and 53Hz-20kHz (±8dB), and average sensitivity of 90.8dB measured 1W/1M. The system shall include a factory-mounted dual voltage (70V/25V) transformer with primary taps at .25, .5, 1, 2, and 5W, and a .147 cu.ft. steel backbox with black powder epoxy finish. Speaker connections shall exit the enclosure through a metal clamp.
