Full Range Ceiling Tile Loudspeaker for Professional Installations
The JBL LCT 81C/TM is a full-range ceiling-tile loudspeaker designed for fast, hassle-free installation in metric-style suspended ceilings. Measuring 600 x 600 mm (23.6 x 23.6"), this two-pack of speakers is ideal for a wide range of applications, including classrooms, retail environments, corporate offices, reception areas, meeting rooms, lounges, airports, and other commercial spaces. Its shallow 4" (100 mm) depth allows it to fit into locations where traditional ceiling speakers would be too large.
Efficient 8-Inch Dual Cone Driver for Clear Audio
Each tile contains a high-efficiency 8-inch dual-cone driver that delivers reliable performance for both speech and background music. Featuring a Kapton coil former with high-temperature wiring, the driver ensures improved heat dissipation and long-term durability, even in demanding environments. With a frequency range from 100 Hz to 16 kHz, it provides excellent vocal clarity and balanced audio coverage.
Quick Installation Without Cutting Ceiling Tiles
The LCT 81C/TM is designed for easy lay-in installation directly into metric suspended grid ceilings, eliminating the need to cut ceiling tiles. Simply drop the unit into place for a secure and professional fit. Its low-profile design makes it suitable for shallow ceilings or spaces with obstructions, and a perforated metal grille is included for a clean, finished appearance.
Flexible Power Options for Multiple System Configurations
This ceiling speaker supports both high-impedance distributed audio systems and low-impedance direct operation. The integrated multitap transformer allows use on 70V or 100V systems with selectable taps at 10W, 5W, and 2.5W (plus 1.3W for 70V only). For direct low-impedance setups, the speaker operates at 8 ohms with 20W program power capacity. Switching between these modes is simple using the rotary control on the rear enclosure.
High Sensitivity for Maximum Output
With a sensitivity rating of 96 dB, the JBL LCT 81C/TM delivers strong output levels even with modest amplifier power. This efficiency makes it an excellent choice for installations where cost-effective amplification is a priority, ensuring that every listener in the coverage area hears clear, intelligible sound.
Wide 100-Degree Conical Coverage Pattern
The LCT 81C/TM’s 100-degree conical dispersion ensures even sound coverage across the listening area, reducing audio hot spots and dead zones. This makes it well suited for distributed audio systems in larger rooms, where consistent sound quality is essential.
Certified for Safety and Reliability
Designed to meet commercial building standards, the JBL LCT 81C/TM is UL1480A and UL2043 certified for use in ceiling plenum spaces. These safety certifications ensure compliance with fire codes and other installation requirements, making it a dependable choice for professional audio contractors.
