JBL Professional JBL Control 24C Coaxial in-ceiling loudspeaker

The Control 24C is the small in-ceiling speaker for background music and music-plus-paging: a coaxially mounted 100 mm woofer with a butyl rubber surround and a 19 mm titanium-coated diffraction-loaded tweeter. Coverage is 130 degrees conical and maximum output is 102 dB in low impedance.

A formed steel blind-mount backcan is included, so it is rated for air-handling spaces per UL1480 and UL2043 without buying anything else. Ceiling cutout is 168 mm; a cardboard template, a C-shaped support backing plate and two tile support rails for 2 x 4 ft or 600 x 1200 mm tiles come in the box. Termination is a removable 4-pin locking connector with screw-down terminals. Price shown is per speaker.
