(Sold as a pair)
The pair of black Professional Series Control 14C/T Two-Way 4" Coaxial Ceiling Loudspeakers from JBL is designed to provide enhanced sound quality for a wide variety of 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 a 4” (100mm) high-tech cone driver and a 19mm soft-dome, liquid-cooled tweeter mounted in a vented, paintable baffle made of UV-resistant UL94-V0 and UL94-5HB material, with a pre-attached blind-mount backcan for quick and easy installation. The 120° coverage delivers consistent sound quality for listeners located both off and on axis.
The 4” (100mm) low-frequency driver is designed with a lightweight, high temperature anodized aluminum voice coil former and high temperature grade voice coil for stable performance and reliability under long-term, high-power working conditions. The butyl rubber surround provides long-term durability and good sonic damping while the polypropylene cone is water and humidity resistant. The FEA-optimized motor construction and cone geometry, along with linear suspension spider design, allows for a smooth frequency response and more consistent off-axis performance. The 3/4” (19mm) high-frequency driver features a highly damped, treated silk dome for clear and warm sound, a lightweight Kapton voice coil for improved high-frequency response and reliability, low viscosity liquid cooling for power handling and reliability, and a wide dispersion waveguide design to produce wide coverage and smooth frequency response.
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. Suitable for a wide variety of projects, the Control 14C/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 25W, 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.
