Bose Professional DesignMax DM5C In-Ceiling Loudspeakers (Black, Pair)

Bose Professional DesignMax DM5C is an in-ceiling loudspeaker pair designed for indoor commercial audio installations. It enables full-range sound reproduction for system designers and integrators, supporting distributed background and foreground audio workflows. This makes it ideal for spaces where consistent coverage and discreet ceiling integration are required.

The loudspeakers operate using coaxial two-way drivers with a passive crossover and Dispersion Alignment system. They support low-impedance operation as well as 70V and 100V distributed systems through selectable transformer taps. Installation is performed using QuickHold spring-loaded mounting arms for ceiling applications.

The system supports applications that require clean aesthetics and uniform sound distribution. It is suited for retail, hospitality, worship, and conference environments. The design allows integration with compatible Bose Professional electronics and accessories.
