JBL Control 24CT Micro - 30W 4-inch Passive 2-Way 70V/100V Low Profile Ceiling Loudspeaker with Backcan and 150-Degree Coverage in White Finish

The JBL Professional Control 24CT Micro is a compact, high-performance ceiling loudspeaker designed to deliver full, rich sound for a variety of background music, paging, and foreground sound systems. Offering exceptional versatility and easy integration into diverse commercial environments, this speaker is ideal for restaurants, retail stores, professional offices, airports, and other venues that require reliable, high-quality sound in a low-profile design. With its broad 150° coverage and smooth frequency response, the Control 24CT Micro ensures consistent sound throughout the listening area, providing clear, balanced audio for both music and paging applications.

The Control 24CT Micro features a 4.5-inch woofer made from injection-molded graphite (IMG) with a butyl rubber surround, providing durability and long-term performance even in challenging environments. The woofer's construction ensures excellent low-frequency output, while the 12mm polycarbonate tweeter extends the high-frequency response, ensuring clarity and detail in the audio. The combination of these two drivers delivers a wide frequency range, from 85 Hz to 25 kHz, and provides consistent, low-distortion sound that is perfect for medium-volume applications.

For ease of installation, the Control 24CT Micro comes equipped with a multitap transformer, making it ideal for use in 70V/100V distributed systems. The 9W multi-tap transformer enables the speaker to be installed with different power settings, ensuring versatility for various system designs. The speaker also features screw-down terminals for secure wiring, and the enclosure is made of formed steel for durability. The backcan, grille, and tile rails are all included, making the installation process straightforward and quick. Additionally, the C-shaped support backing plate ensures the speaker is securely installed, even in suspended ceiling applications.

The Control 24CT Micro is designed to be both efficient and durable. Its wide coverage angle of 150° allows for fewer speakers to be used while still achieving excellent sound distribution, reducing the cost of the installed sound system without sacrificing performance. The speaker's compact, low-profile design allows it to blend seamlessly into a wide range of interior decor styles, while the white finish ensures it fits well in a variety of environments. Additionally, the speaker's paintable trim and baffle allow it to be customized to match the aesthetic of any space.

With its high sensitivity of 86 dB and maximum SPL of 94 dB at 1 meter, the Control 24CT Micro provides clear, loud, and distortion-free audio even in environments with higher ambient noise. Whether used in background music systems or for paging in larger installations, the Control 24CT Micro ensures full, natural sound with minimal distortion. It is also equipped with UL-listed components and complies with safety standards, making it suitable for use in air-handling spaces and other commercial environments that require high standards of safety and performance.
