Biamp 920-01545-20000 CM3T

Product Overview

The Biamp CM3T is a 3-inch dual-cone in-ceiling loudspeaker for background music and voice paging in commercial spaces. This white model drops into a ceiling for a discreet, low-profile source of clear speech and music in retail, hospitality, and office environments. With an onboard 70V/100V transformer and low-impedance capability, this commercial ceiling loudspeaker works in distributed audio systems of almost any size, and its compact 105 mm footprint suits tight ceiling layouts.

Product Description

The CM3T uses a 3-inch coated-paper dual-cone driver tuned for intelligible speech and even background music rather than high output. It ships with a multi-tap transformer offering 70V taps of 6, 3, 1.5, and 0.75 watts and 100V taps of 6, 3, and 1.5 watts, so integrators can balance level across a distributed line at design time. The loudspeaker can also run in low impedance at 16 ohms, with 10 watts RMS and 20 watts dynamic power handling, for smaller stand-alone systems. Its frequency response of 120 Hz to 18 kHz and 87 dB sensitivity suit the paging and music duty typical of commercial ceilings.

Installation is quick thanks to a two-spring mounting system and a 1 to 15 mm grip range that accommodates a variety of ceiling thicknesses, dropping into an 85 mm cutout. An aluminum grille gives a clean finished look, and the wide 180-degree vertical dispersion at 1 kHz spreads sound evenly below the speaker. The same model is offered in a black CM3T for darker ceilings, and additional commercial loudspeakers are listed in the Biamp collection.
