Description
Priced individually, but sold in pairs.
The Desono CM30DTD two-way 4.25" ceiling loudspeaker delivers crystal clear audio for all your public address and background music needs. Its 4.25" polypropylene woofer and 1" 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.
Features:
- Requires only 5.2" (131 mm) mounting depth
- High speech intelligibility coupled with full-range music reproduction
- Thin-edge, magnetically attached grille
- Tap switch allows for 70V/100V or 16 ohm low impedance operation
- Tuned bass reflex port for optimized low frequency performance
- Loudspeaker overload protection for 24/7 failsafe operation
- ETL listed to conform with UL Std 1480A and UL 2043; Certified to CSA C22.2#62368-1
