About This Product

The 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.

JBL Professional Control 24CT-BK Ceiling Speaker Features:
  • Coaxially mounted 100 mm (4 in) woofer with butyl rubber surround and 19 mm (¾ in) titanium coated diffraction-loaded tweeter.
  • High power, wide frequency response and low distortion for high sound level capability.
  • Wide coverage allows fewer speakers, reducing the cost of the installed sound system without sacrificing performance.
  • Packaged with grille, backcan and tile rails for fast installation and easy dealer stocking.
  • Black baffle and grille works well in black and dark ceiling.

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 130° coverage pattern allows for fewer speakers to be used, making for a simpler and less expensive installation.
