The JBL LCT 81C/T is a low-profile 2′ × 2′ lay-in ceiling tile loudspeaker designed for fast installation and reliable commercial sound performance. Featuring a high-efficiency 8-inch (200 mm) dual-cone driver, it delivers clear speech and smooth background music for offices, corporate spaces, hotels, retail stores, hospitals, and educational institutions. This speaker fits directly into standard 2′ × 2′ suspended ceiling grids, eliminating the need for tile cutting and reducing installation time. With high 96 dB sensitivity, it produces excellent sound output even with low-power amplifiers, making it ideal for distributed PA and background music systems.
