JBL Control 24C Micro - 30W 4-inch Passive 2-Way Low Profile Ceiling Loudspeaker with Backcan and 150-Degree Coverage in White Finish

The JBL Professional Control 24C Micro is a compact yet powerful ceiling loudspeaker designed to deliver high-quality sound for background music and paging systems. Its low distortion and smooth frequency response make it ideal for applications requiring clear audio in medium to low SPL environments. The Control 24C Micro is especially suited for commercial spaces such as restaurants, retail stores, professional offices, airports, and hospitality venues, providing superior performance in environments that require both aesthetics and excellent audio quality. This speaker excels in both foreground and background music systems, ensuring a rich, full sound while maintaining a wide coverage area.

With a 4.5-inch (115 mm) woofer featuring an injection-molded graphite cone and a butyl rubber surround, the Control 24C Micro ensures long-lasting durability and superior sound reproduction. The woofer's design enhances low-frequency output, while the 0.5-inch (12 mm) polycarbonate tweeter delivers crisp, clear highs. The combination of these drivers provides a balanced, smooth frequency response from 85 Hz to 25 kHz, making the speaker perfect for full-range sound applications. The 150° coverage angle ensures that sound is evenly distributed across the listening area, reducing the need for multiple speakers and simplifying the installation process.

The Control 24C Micro is available in both 8-ohm impedance for direct connection in low-impedance systems and 70V/100V versions with a multi-tap transformer (Control 24CT Micro). This flexibility makes it easy to integrate into various distributed audio systems. The 30W continuous program power handling (15W continuous pink noise) of the 24C Micro ensures that it can deliver high output levels while maintaining audio fidelity. The 24CT Micro, with its multi-tap transformer, includes 9W, 4W, 2W, 1W, and 0.5W taps for use in distributed systems, making it a versatile choice for large-scale installations.

Installation is quick and easy, thanks to the included backcan, grille, and tile rails, which make the speaker compatible with both 2x4 ft and 600 mm ceiling tiles. The innovative C-shaped support backing plate ensures that the speaker remains securely in place, while the included tile bridge rails provide additional support when mounted on a T-channel grid. The entire installation process can be completed from below the ceiling, and a cutout template is provided for accurate marking. The speaker is designed for use in air-handling spaces and meets various UL, CE, and VDE safety standards, ensuring reliability and safety in commercial environments.

Whether used for background music in a restaurant or as part of a paging system in a retail store, the Control 24C Micro delivers exceptional performance in a compact, aesthetically pleasing package. Its ability to handle a wide frequency range, coupled with its 150° coverage, ensures that it can be used in a variety of applications, providing a consistent and clear listening experience throughout the space.
