High-Performance Ceiling Loudspeaker for Clear and Balanced Audio
The Desono CM30DTD is a premium two-way 4.25-inch ceiling loudspeaker designed to provide outstanding audio clarity for public address systems and background music applications. Featuring a polypropylene woofer and a 1-inch tweeter, it delivers high sound pressure levels (SPL) with minimal distortion, ensuring clear speech intelligibility and full-range music reproduction. Ideal for commercial spaces, conference rooms, and multi-zone sound systems, this speaker blends seamlessly into any environment while delivering exceptional audio performance.

Flexible Installation with Low-Profile Design
With a shallow mounting depth of only 5.2 inches (131 mm), the CM30DTD is designed for easy integration into ceilings with limited space. Its thin-edge grille attaches magnetically, providing a modern and discreet appearance while allowing for quick removal during maintenance. The speaker’s compact design makes it an excellent choice for applications where aesthetics and performance are equally important.

Versatile Connectivity and Multi-Use Applications
The CM30DTD supports a 5-position switchable transformer ranging from 1.75W to 30W, allowing operation in both 70V/100V constant-voltage systems and 16-ohm low-impedance mode. This versatility makes it suitable for large areas requiring consistent sound coverage, including conference rooms, hotels, retail spaces, and restaurants. Its built-in bass reflex port ensures enhanced low-frequency response, making music playback richer and more immersive.

Quick and Hassle-Free Installation
Designed with the installer in mind, the CM30DTD can be blind-mounted from below the ceiling, eliminating the need for complex mounting procedures. The front-mounted tap switch allows for easy power selection adjustments without requiring access to the ceiling cavity. Additionally, the grille can be painted to match the room décor, ensuring seamless integration into any space.

Reliable and Certified for Commercial Use
Built for continuous operation, the CM30DTD features loudspeaker overload protection to prevent damage during extended use. It meets key safety certifications, including ETL listing for UL 1480A and UL 2043 compliance, and conforms with City of Chicago codes. The speaker is also certified for use with Zoom Rooms, making it an excellent choice for conference and collaboration environments where speech clarity is critical.
