Ceiling Tile Speaker for Grid Installations

The JBL LCT 81C/T is a full-range loudspeaker pair designed to lay directly into a standard US 2 ft x 2 ft suspended grid ceiling. No tile cutting is required, which keeps installation fast and clean. Its low-profile depth of 100 mm suits plenums where deeper units will not fit. These speakers target paging and light-to-medium music in classrooms, retail, offices and similar commercial spaces.

96 dB Sensitivity Drives Output at Low Taps

The 200 mm dual-cone driver delivers a very high 96 dB sensitivity, so maximum sound level is reached even at low transformer tap settings. A 25 mm voice coil on a Kapton former with high-temperature wire improves power dissipation and long-term reliability. The built-in 10 Watt transformer supports both 70V and 100V distributed line systems, giving installers voltage flexibility without external hardware.

Fits Standard Grids and Frees Plenum Space

Because the speaker rests in the grid, it needs no cut-out, no separate baffle and no extra mounting hardware. The 100 mm depth leaves room above the tile for ductwork, conduit or insulation. It is not suited for applications demanding deep bass extension, high-SPL reinforcement or weather-resistant enclosures. Installers seeking a drop-in solution for distributed 70V or 100V lines will find the pair integrates with existing grid infrastructure.
