 JBL C24CT-BK Ceiling Speaker with Transformer,Black

The JBL Control 24CT-BK is a compact ceiling speaker providing premium performance in background, foreground and music-plus-paging sound systems. The Control 24CT-BK is perfectly suited for a wide variety of applications from professional offices and airports to restaurants and specialty retail stores. High power handling, wide frequency response and low distortion make the Control 24CT-BK ideal for sound systems requiring a higher fidelity sound from ceiling loudspeakers.

The premium performance capability ensures excellent sound character, providing pleasant, enveloping sound throughout the listening area. The Control 24CT-BK includes a multitap transformer for 70V/100V systems. The computer-optimized ported enclosure delivers warm, smooth bass response. Low frequency output can be further augmented with the addition of one of the Control Contractor subwoofer models. The 100 mm (4 in) woofer features a polypropylene-coated cone and pure butyl rubber surround for long life, even in high humidity environments. An aluminum voice coil former provides extra cooling for greater long-term power handling. The coaxially mounted 19 mm (3/4 in) titanium coated tweeter provides crisp, clear highs. Diffraction-loading of the tweeter provides wide, even coverage of the listening area. The extremely broad 130deg. coverage pattern allows for fewer speakers to be used, making for a simpler and less expensive installation.
