Biamp 920-01548-20000 CM4T
Product Overview
The Biamp CM4T is a compact 4-inch dual-cone in-ceiling loudspeaker for paging and background music where a small, unobtrusive speaker is needed. This white model suits corridors, restrooms, small retail areas, and fill locations in larger distributed audio systems. The CM4T operates as a 16-ohm loudspeaker or on a 70V/100V line with a 6-watt transformer. Its small cutout and low profile make it easy to place in tight ceiling areas.
Product Description
The Biamp CM4T ceiling speaker uses a 4-inch coated-paper dual-cone driver to reproduce clear speech and background music from a compact enclosure. In 16-ohm use it can be combined with other CM-series speakers in low-impedance zones, and for 70V/100V distributed audio it includes a 6-watt transformer with several power taps for level balancing. Its small 135 mm outside diameter and 74 mm depth make the CM4T well suited to corridors, restrooms, and infill positions where a larger ceiling speaker would be excessive. The CM4T is a practical companion to larger CM-series models in the same system, delivering consistent voicing for even coverage. This white unit (RAL9010) is the color sibling of the CM4T-BL (black); for higher output in main listening areas, pair it with the CM6T. Browse the Biamp collection for amplifiers and companion ceiling loudspeakers.
