Biamp Desono CM30DTD 4.25” two-way thin edge design ceiling loudspe...
Product Overview
The Biamp Desono CM30DTD is a 4.25-inch two-way thin-edge ceiling loudspeaker, sold as a pair. It delivers dynamic music reproduction with defined bass response thanks to a sealed back can and ported bass design. It is capable of 16 ohm or 70 V/100 V operation, selectable on the front panel. A thin-edge grille with integrated neodymium magnets provides elegant integration.
Product Description
The CM30DTD can be combined with other models in the CM range to create the right combination for a space. A solid cable management system, loudspeaker clamps, and integrated seismic safety tabs make it an installer-friendly choice. The thin-edge grille mounts via strong integrated neodymium magnets and is easily paintable in any RAL color, while included tile bridge support rails prevent ceiling tile sag. Two fast-screwing loudspeaker clamps and integrated seismic safety tabs speed installation. The minimal built-in depth preserves acoustical performance, and the enclosure is ABS plastic with a steel grille in white (RAL9010).
