2 JBL LCT 81C/T Commercial Drop Ceiling Tile Speakers For Office/Restaurant/Cafe

The JBL LCT 81C/T is a full-range ceiling speaker that lays directly into a 2 ft x 2 ft US-style suspended grid, so nothing has to be cut and the job site stays clean. This pair covers a small zone such as a cafe dining area, a pair of classrooms, or a reception and waiting room. At only 4.1 inches deep, each speaker clears ductwork, conduit, and shallow plenums that will not accept a deeper back can.

Each unit carries a 200 mm (8 in) dual-cone driver with a 25 mm voice coil, Kapton coil former, and high-temperature wire for steady long-term operation. Sensitivity of 96 dB is high for a ceiling speaker, which means a low tap setting still produces usable level and a small amplifier can feed a large number of units. Coverage is 100 degrees conical, and the voicing is tuned for speech clarity as well as background and foreground music.

The built-in 10 Watt transformer works on 70V or 100V distributed lines with taps at 10W, 5W, and 2.5W, plus a 1.3W tap on 70V. A rotary switch on the side of the rear enclosure changes taps without pulling the speaker out of the grid. You can also bypass the transformer and run 20W direct at 8 ohms from a low impedance amplifier.

Wiring lands on bare-wire terminals inside a touch-proof compartment, with knock-outs on the top and side. Two seismic tabs plus four corner holes tie the speaker to the ceiling deck, and UL1480A and UL2043 listings allow use in air handling spaces. Steel enclosure, steel baffle, white perforated grille.
