Biamp 920-01557-20000 CM6T
Product Overview
The Biamp CM6T is a 6.5-inch two-way in-ceiling loudspeaker built for background music and paging in commercial installations. This white model is a cost-effective choice for retail, hospitality, and office spaces that need clear distributed audio. The CM6T operates as a 16-ohm loudspeaker or on a 70V/100V line with a 6-watt transformer. Its IP54-rated construction and aluminum grille suit humid environments.
Product Description
The Biamp CM6T ceiling loudspeaker combines a 6.5-inch reinforced polypropylene woofer with a 1-inch tweeter for low-distortion speech and music reproduction. In 16-ohm use, up to four loudspeakers connect in parallel on each channel of a standard 4-ohm amplifier, which fits typical low-impedance zones. For 70V/100V distributed audio, the CM6T carries a 6-watt transformer with several power taps, making it a practical choice for background music where high output is not required. The ABS housing, moisture-proof polypropylene woofer, and aluminum grille make the CM6T 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. This white unit (RAL9010) is the color sibling of the CM6T-BL (black); for higher output, step up to the CM20T. See the Biamp collection for amplifiers and companion ceiling speakers.

- 6-watt 70V/100V transformer — Multiple power taps let integrators set background-music levels across a distributed zone.
- 16-ohm parallel operation — Up to four CM6T units run in parallel per channel of a standard 4-ohm amplifier for low-impedance zones.
- IP54 moisture resistance — The ABS housing and aluminum grille suit humid spaces where steel grilles would corrode.
