LCT 81C/T Low-Profile Lay-In 2' x 2' Ceiling TileLoudspeaker with 200 mm (8 in) Driver
**QTY 2**
LCT 81C/T is a full-range ceiling speaker designed to lay into a 2 ft x 2 ft US-style suspended grid ceiling, with no cutting of ceiling tiles required, making for an easy and cost-effective installation with a minimum of mess.
Features
This loudspeaker is designed to provide excellent performance for paging and light-to-medium music in a wide variety of applications, including education classrooms, business music systems, retail stores, music/paging systems, airports, reception/waiting rooms, lounges, courtrooms, meeting rooms, and more.
The very high sensitivity of 96 dB provides maximum sound level, even at low tap settings. LCT 81C/T contains a 200 mm (8 in) dual-cone driver with a very high 96 dB sensitivity. The driver features a 25 mm (1 in) diameter voice coil with a Kapton coil-former and high-temperature wire for better power dissipation and long-term reliability. The speaker's built-in 10 Watt transformer provides versatility by allowing use on 100V or 70V distributed loudspeaker lines, as well as at 8 ohms (low impedance) for driving directly from a low impedance power amplifier. Adjusting is convenient via a rotary switch on the side of the rear enclosure. Two safety seismic attachment tabs are provided for securing to ceiling deck, plus 4 holes are provided -- one in each corner. The color of the perforated grille is white.

- Very low-profile at just 103 mm (4.1 in) deep, to fit into ceilings that are shallow or that contain obstructions.
- Easy bare-wire connection in protected compartment. Wire entrance from either top or side via knock-out.
- Very high 96 dB sensitivity turns power from small amplifiers into maximum sound level for listeners.
- Designed for high speech intelligibility.
