JBL Control 24C - 80W 4-inch Passive 2-Way Ceiling Loudspeaker with Backcan and 130-Degree Coverage in White Finish

The JBL Professional Control 24C is a compact yet high-performance ceiling loudspeaker designed for a wide range of commercial and professional applications. Whether for background music, foreground music, or music-plus-paging systems, the Control 24C offers exceptional sound quality and reliability. This speaker is ideally suited for spaces such as professional offices, retail stores, airports, restaurants, and educational facilities. Its ability to deliver high-fidelity sound, combined with its versatile mounting options, makes it an excellent choice for a variety of installation environments.

The Control 24C features a coaxial design with a 100 mm (4-inch) polypropylene-coated woofer and a 19 mm (3/4-inch) titanium-coated tweeter. This configuration ensures smooth, balanced sound across a wide frequency range. The woofer is equipped with a butyl rubber surround, providing enhanced durability and ensuring long-lasting performance, even in high-humidity environments. The aluminum voice coil former improves cooling, allowing the speaker to handle higher power levels while maintaining consistent sound quality. The titanium-coated tweeter is diffraction-loaded, ensuring crisp, clear high frequencies and wide, even coverage. With its 130° conical coverage pattern, the Control 24C provides excellent sound dispersion, reducing the need for multiple speakers in the system, thereby lowering installation costs without sacrificing performance.

JBL's exclusive SonicGuard overload protection system is incorporated into the Control 24C to ensure reliability and protect the speaker from overload damage. This system is inaudible to the listener but improves the overall performance and longevity of the speaker. The Control 24C's compact design and efficient coverage make it an excellent choice for installations where high-quality sound is required without the need for numerous speakers. The system is capable of handling 80 Watts of continuous program power and 40 Watts of continuous pink noise, delivering a maximum SPL of 102 dB at 1 meter, ensuring the ability to fill medium to large spaces with clear and rich sound.

The speaker comes with a pre-attached backcan and grille for easy installation, and it includes tile rails for compatibility with both 2x4 ft or 600x1200 mm ceiling tiles. The Control 24C is designed with a 16-ohm impedance, making it ideal for systems where multiple speakers can be wired in parallel without the need for a more expensive constant voltage distributed system. The optional Control 24CT version includes a multitap transformer for 70V/100V systems, allowing flexibility in large-scale installations.

With its high-performance capabilities and elegant design, the Control 24C is available in a white finish, blending seamlessly into a variety of interior designs. The speaker is built to handle a wide range of environmental conditions, with a weather-resistant backcan and components designed to withstand humidity and exposure to the elements, making it suitable for both indoor and outdoor use. Additionally, the speaker meets various safety and environmental standards, ensuring reliability and performance in demanding installations.
