JBL CONTROL24C 4" Ceiling Speaker.
The CONTROL24CT has 70V/100V taps at 8W, 4W, 2W, 1W (and 0.5W for 70V only)
The Control 24C is a compact ceiling speaker providing premium performance in background, foreground and music-pluspaging sound systems. The Control 24C 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 24C 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 24C’s 16 ohm impedance allows use of multiple speakers in parallel without having to use a more expensive constant voltage distributed system. The Control 24CT version includes a multitap transformer for 70V/100V systems.

JBL’s exclusive SonicGuard overload protection is a non-invasive loudspeaker protection system that is inaudible to the listener, ensuring reliability while providing full fidelity sound. 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 butylrubber 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 130° coverage pattern allows for fewer speakers to be used, making for a simpler and less expensive installation.
