JBL Control 45C/T - 150W 5.25-inch Passive 2-Way 70V/100V Ceiling Loudspeaker with Backcan and 120-Degree Coverage in White Finish

The JBL Professional Control 45C/T is a premium 5.25-inch passive 2-way ceiling loudspeaker designed to provide exceptional sound performance with an ultra-wide coverage pattern, making it ideal for various commercial and residential applications where high fidelity and consistent sound dispersion are essential. With its innovative design, the Control 45C/T combines powerful bass extension, clear high frequencies, and uniform coverage across a large listening area, all within a compact ceiling footprint.

At the heart of the Control 45C/T is JBL's exclusive Radiation Boundary Integrator (RBI) technology, which utilizes a conical waveguide to seamlessly control both low and high frequencies. This technology ensures that the high frequencies are precisely controlled by a large waveguide, while the low-frequency sound projects through specially designed apertures in the RBI, providing a uniform and consistent coverage. As a result, the Control 45C/T produces an extremely consistent 120-degree broadband coverage pattern that eliminates high-frequency beaming, offering a smooth and natural sound character throughout the listening space.

The Control 45C/T features a 130mm (5.25 in) polypropylene-coated paper cone with a pure butyl rubber surround, providing a durable and reliable driver that delivers powerful bass extension down to 55 Hz. The coaxial design houses a 20mm (0.75 in) soft dome tweeter that is cooled by FerroFluid technology, improving power handling and reducing power compression. This combination allows the Control 45C/T to provide excellent clarity for speech and vocals, as well as a wide frequency response for music, making it an ideal solution for both foreground and background sound in a variety of settings.

The loudspeaker's easy-to-install design features an integrated backcan that allows for a straightforward "blind-mount" installation, and it is packaged with a grille and tile rails for enhanced flexibility and ease of mounting. The 8-ohm and 70V/100V operation options make the Control 45C/T versatile for use in both low-impedance and distributed sound systems. When combined with the Control 40CS/T subwoofer, the Control 45C/T delivers an incredibly natural-sounding, powerful subwoofer-satellite system that provides superior sonic performance across a wide bandwidth.

With its excellent sound quality, versatile installation features, and wide coverage, the JBL Professional Control 45C/T is an excellent choice for commercial spaces, retail environments, hospitality venues, and residential applications that demand consistent audio performance with minimal visual impact.
