Biamp Desono CM30DTD 4.25" 2-Way Ceiling Speakers

The Desono CM30DTD two-way 4.25-inch ceiling loudspeaker delivers crystal clear audio for all your public address and background music needs. Its 4.25-inch polypropylene woofer and 1-inch tweeter results in a high SPL and extremely low distortion, ensuring exceptional clarity over the entire frequency spectrum.

The CM30DTD utilizes a 5-position switchable transformer ranging from 1.75W to 30W with low-impedance bypass for constant-voltage operation, making it an excellent choice for large areas of BGM.

Designed with the installer in mind, they can be blind-mounted from below the ceiling, and feature a magnetic grille for easy toolless installation and removal that can also be painted to match the room decor. Additionally, the tap switch is located on the face of the loudspeaker, so adjustments can be made without requiring ceiling access.

Certified for use with Zoom software.
