The Desono CM20DTS is a 2-way 4.25-inch ceiling loudspeaker that delivers crystal clear audio for all your public address and background music needs. Its 4.25-inch coated paper cone woofer and a 1-inch tweeter results in a high SPL and extremely low distortion, ensuring exceptional clarity over the entire frequency spectrum.
The CM20DTS utilizes a 5-position switchable transformer ranging from 1.25W to 20W (has a rotatable 70V/100V power tapping selector on the front and offers 16 ohms connectivity) 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.
Desono CM20DTS loudspeakers are an ideal choice for a multitude of environments that demand superior speech intelligibility and full range music reproduction.
