System installers looking for a metric ceiling speaker that's designed for quick and easy installation will be impressed with the JBL LCT 81C/TM, a 2-pack of full-range 23.6 x 23.6" (600 x 600mm) ceiling-tile loudspeakers that's well suited for a variety of applications, including classrooms, business music systems, retail stores, music/paging systems, airports, reception/waiting rooms, lounges, courtrooms, meeting rooms, and more. Each tile is suspended in a ceiling grid with no cutting necessary. With a depth of only 4" (100mm), the LCT 81C/TM fits into locations where deeper loudspeakers do not.
Each tile is fitted with a highly efficient 8" dual-cone driver with a Kapton coil-former, which utilizes a high-temperature wire for better power dissipation and long-term reliability. The speaker's built-in 10W transformer provides versatility by allowing use on 100 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. The speaker offers a frequency range of 100 Hz to 16 kHz, ensuring high speech intelligibility.
