Biamp CM10TB 5.5-Inch Full-Range Ceiling Mount Loudspeaker, Pair

The lowest cost back can speaker in Biamp’s lineup, the CM10TB is ideal for applications such as paging and background music in a variety of venues but is specifically designed to provide exceptional performance when paired with Vocia voice communication system. The CM10TB delivers crystal-clear voice intelligibility-a critical requirement for any speech reinforcement application - while its wide, uniform coverage surpasses that of competitors.

The CM10TB uses preassembled back-can construction that allows it to be easily mounted on ceiling tiles or drywall ceilings, providing unmatched simplicity for significant installation cost savings. UL1480A and UL2043 certified, the CM10TB also meets the City of Chicago plenum space wiring requirements and comes with additional accessories for new construction installation and safety cable attachment.

The CM10TB offers the flexibility of low impedance or 70 V/100 V operation while featuring a front face wattage selector switch for adjusting tap levels before installing the grille.
