4" Ceiling Speaker, 70V, White


The Control 24CT is perfectly suited for a wide variety of applications from professional offices and airports to restaurants and specialty retail stores. 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. 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. The 100 mm (4") woofer features a polypropylene-coated cone and pure butyl rubber surround for long life, even in high-humidity environments, and an aluminum voice coil former provides extra cooling for greater long-term power handling. The coaxially mounted 19 mm (3/4") titanium-coated tweeter provides crisp, clear highs, with diffraction-loading providing 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. 70V/100V transformer taps.
