The Professional Series Control 12C/T 3″ Compact Ceiling Loudspeakers from JBL is designed to provide an enhanced sound quality for a wide variety of low to medium volume applications such as music cafes, business music systems, retail stores, music/paging systems, airports, reception/waiting rooms, lounges, courtrooms, convention centers, hotels, educational facilities, and more

These full-range ceiling speakers consist of 3” (76mm) wide-bandwidth cone driver mounted in a vented, paintable baffle made of UV-resistant UL94-V0 material, with a preattached blind-mount backcan for quick and easy installation. The 130° coverage is especially wide, delivering consistent sound quality for listeners located both off and on axis.

The high technology cone driver is designed with a lightweight high temperature Kapton voice coil former and aluminum coupling ring to reduce distortion and extend the high-frequency response of the system.

The FEA-optimized motor construction and cone geometry allow for smooth frequency response and improved off-axis performance. A high temperature-grade voice coil ensures stable performance under long-term, high-power working conditions.

The butyl rubber surround provides long-term durability and good sonic damping, and the polypropylene cone is water and humidity resistant.

The removable locking connector has screw terminals for secure wire termination and loop through terminals. A dual strain relief assembly provides clamping for use with cable or flex conduit. The compact backcan extends only 5.4” (138mm) behind the baffle, allowing the speaker to fit into more shallow ceiling areas.

Suitable for a wide variety of projects, the Control 12C/T Loudspeakers are switchable for use as either 8Ω, low-impedance speakers or as part of a 70 or 100V distributed loudspeaker system with a 15W, multi-tap transformer.

The speakers come complete with 2 tile rail supports, a C-ring support backing plate, cutout template, paint shield, and a grille. A safety seismic attachment ring is provided on the top surface.
