JBL LCT 81C/T | 2x2 Feet Ceiling Tile Loudspeaker, Pair

The JBL LCT 81C/T Ceiling Tile Loudspeaker Pair is designed for easy, mess-free installation into 2x2 US-style suspended grid ceilings without the need for cutting ceiling tiles. These ceiling speakers are ideal for a variety of settings, including educational classrooms, retail stores, business music systems, airports, waiting rooms, lounges, courtrooms, and meeting rooms. The LCT 81C/T offers a full-range audio experience with exceptional sensitivity, ensuring maximum sound level even at low tap settings. The speaker features an 8-inch dual-cone driver with a high 96 dB sensitivity, making it perfect for both paging and light to medium music applications.

Designed with a low-profile depth of just 100 mm (4 inches), these speakers fit seamlessly into shallow ceilings or areas with obstructions. The 10-watt transformer built into the speaker provides versatility, allowing it to be used on 70V or 100V distributed loudspeaker lines as well as at 8 ohms for direct connection to a low impedance power amplifier. Adjustments are easily made via a rotary switch located on the rear enclosure, and the perforated grille in white seamlessly integrates with most ceiling designs. Two seismic attachment tabs ensure secure installation, adding an extra layer of safety.
