Description
JBL LCT 81C/TM 600mm × 600mm Lay-In Ceiling Tile Speaker with 8" Driver
The JBL LCT 81C/TM is a professional-grade ceiling speaker engineered for distributed audio systems in commercial and institutional installations. Its compact lay-in design integrates seamlessly into standard metric suspended grid ceilings without requiring tile modification, making it ideal for retrofits in offices, retail environments, and hospitality venues where clean aesthetics matter.
Installation & Form Factor
This speaker mounts directly into a 600mm × 600mm metric ceiling grid with minimal preparation—no cutting of ceiling tiles required. The unit features two safety seismic attachment tabs for secure anchoring to the ceiling deck and four corner mounting holes, plus a shallow 103mm (4.1 in) depth that fits standard plenum cavities. UL1480A and UL2043 certifications confirm its suitability for use in ceiling plenum spaces, meeting fire and safety codes for enclosed air plenums.
Audio Performance & Impedance Options
The 200mm (8 in) dual-cone driver delivers 96 dB sensitivity with a robust 25mm (1 in) voice coil wound on a Kapton coil-former and high-temperature wire for reliable operation under sustained use. A built-in 10 Watt transformer provides flexible wiring: 100V/70V distributed loudspeaker line compatibility for multi-speaker system configurations, or direct 8 ohms low-impedance operation for stand-alone connections. A rotary adjustment switch on the rear enclosure allows quick level tuning without tools.

At a Glance
The JBL LCT 81C/TM is a commercial-install ceiling speaker with an 8-inch dual-cone driver and 96 dB sensitivity, purpose-built for even coverage in offices and retail spaces rather than music recording or critical listening. Its 100V/70V transformer and 8-ohm direct-wire option make it adaptable to distributed systems, while UL plenum certifications and shallow mounting depth simplify integration into metric suspended grids. Use it for background music, speech reinforcement, or system fill in installations where neutral, consistent audio matters more than tonal character.

Frequently Asked Questions
What does 'metric 600mm × 600mm lay-in' mean, and will it fit my ceiling?
This speaker mounts directly into metric-sized suspended ceiling grids (600mm square) without cutting tiles. Its 103mm shallow depth fits standard plenum cavities. It is NOT compatible with US/imperial ceiling grid sizes (typically 2×2 or 2×4 feet).
