Biamp Desono CM20DTS 4.25” two-way thin edge design ceiling loudspeaker 100-70 volt / 20 watts, 16 ohms / 60 watts, white, front frame integrated neodymium magnets and shallow back can (Pair)

Sold as a pair, with an aesthetically pleasing design and a dynamic natural sound, the Community CM20DTS 4.25" 2-way paper cone ceiling speaker is ideal for high-quality background music and voice reproduction in high visibility environments.

A shallow depth of 3.3" (83.5mm) makes the CM20DTS suitable for any ceiling structure with little to no modification. Featuring a 4.25" coated paper cone woofer and 1" silk dome tweeter, the CM20DTS produces clear full-range audio with very low distortion. Integrated 3-step protection ensures the speaker operates without fail at high power loads for peace of mind.

The CM20DTS can operate on 70/100V lines with power taps available at 20, 10, 5, and 2.5 watts or as a low impedance 16-ohm speaker. The tap switch is conveniently located on the speaker's front beneath the easily removable magnetic grille, allowing adjustments without requiring ceiling access.
