Biamp 920-01543-20000 CM20T
Product Overview
The Biamp CM20T is a 6.5-inch two-way in-ceiling loudspeaker for speech and background music in commercial spaces. This white model suits retail, hospitality, and corporate installations that need clear paging and music from a compact ceiling speaker. The CM20T works as a 16-ohm loudspeaker or on a 70V/100V distributed line, so it fits a wide range of system designs. Its IP54-rated build and aluminum grille make it suitable for humid environments.
Product Description
The Biamp CM20T ceiling loudspeaker pairs a 6.5-inch reinforced polypropylene woofer with a 1-inch tweeter for low-distortion reproduction of microphone paging and background music. In 16-ohm use, up to four loudspeakers connect in parallel on each channel of a standard 4-ohm amplifier. For 70V/100V distributed audio, the CM20T includes a 20-watt transformer with multiple power taps, useful in high-ceiling rooms or spaces with background noise where extra output is needed. The ABS housing, moisture-proof woofer, and aluminum grille make the CM20T suitable for high-humidity environments and applications where steel grilles would corrode. A three-screw mounting system with a Quick Fix connector and tapping decal speeds installation, and the hidden screws give a clean ceiling appearance. This white unit (RAL9010) is the color sibling of the CM20T-BL (black); for a larger 8-inch model, see the CMX20T. Browse the Biamp collection for amplifiers and companion ceiling speakers.
