The JBL Control 45C/T is a high-performance in-ceiling loudspeaker designed to deliver exceptional sound quality in applications where space is limited but high fidelity is essential. This premium loudspeaker is engineered to offer extremely wide bandwidth and highly consistent coverage, making it an ideal choice for both small and large installations where sound quality and coverage are critical.

At the heart of the Control 45C/T’s design is JBL’s exclusive conical Radiation Boundary Integrator® (RBI™). This innovative feature incorporates a large waveguide for the tweeter, which helps to manage high-frequency sound dispersion effectively. Low-frequency sounds are projected through specially designed apertures in the RBI, creating a seamless integration between the coaxially mounted drivers. This design approach ensures that the sound character remains exceptionally consistent across the entire listening area, minimizing variation from one location to another.

The wide coverage pattern of the Control 45C/T allows for more efficient use of loudspeakers. Unlike conventional speakers with less consistent coverage, the Control 45C/T’s constant directivity ensures that fewer speakers are needed to cover the same area while still providing superior sound quality. This capability not only enhances the listening experience but also simplifies installation and reduces overall system costs.

The Control 45C/T features a large backcan and a thoughtfully designed low-frequency (LF) driver that contribute to its extended bass response. This design element produces a warm, full-bodied tone that enhances the overall audio experience. The loudspeaker is equipped with a 130 mm (5.25 in) woofer that boasts a polypropylene cone and a pure butyl rubber surround. These materials are chosen for their durability and performance, ensuring long-term reliability and consistent sound quality. Additionally, the coaxially mounted 20 mm (0.75 in) soft dome tweeter includes ferrofluid cooling. This feature enhances power handling capabilities and reduces power compression, resulting in crisp, clear high-frequency output.

The Control 45C/T is versatile in its application, accommodating a range of project requirements. It can be used as an 8-ohm low-impedance speaker for straightforward connections or integrated into a 70V/100V distributed loudspeaker system. This flexibility makes it suitable for a variety of environments, from residential to commercial spaces, where high-quality audio and effective sound distribution are needed.

Overall, the JBL Control 45C/T stands out for its ability to deliver consistent, high-fidelity sound across a wide bandwidth, all within a compact design. Its advanced features, including the conical Radiation Boundary Integrator® (RBI™) and high-quality driver components, ensure that it meets the demanding needs of professional audio applications. Whether used in a small room or a large space, the Control 45C/T provides superior sound coverage and performance, making it a valuable addition to any audio system.
