Lowell LT-410-72-BB 4in Tile Ceiling Speaker

The Lowell LT-410-72-BB is a 4-inch tile ceiling speaker built for suspended tile ceilings. Lowell specifies a 15W high-compliance driver, a dual-voltage 25V/70V transformer with taps down to a quarter watt, and a steel backbox that carries the speaker leads out through a metal clamp for a fast connection.

The patented integral T-bar mount supports the neighboring cut tile and replaces half of a non-tegular 2x2 ceiling tile or one-fourth of a non-tegular 2x4 tile, with a restraint tab and hole for two-cable code compliance. Assembled in the U.S.A. with U.S. steel and global components. Specifications as published by Lowell Manufacturing.
