Bose Professional DesignMax DM3SE Surface-Mount Loudspeakers (Pair)

Bose Professional DesignMax DM3SE is a surface-mount loudspeaker pair designed for indoor and outdoor 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 venues where weather resistance and controlled coverage are required.

The loudspeakers operate using coaxial two-way drivers with a passive crossover and the Dispersion Alignment system. They support low-impedance operation as well as 70V and 100V distributed systems through selectable transformer taps. Installation is performed using the QuickHold mounting system with an included U-bracket.

The system supports applications that require flexible surface mounting and consistent sound distribution. It is suited for hospitality, retail, worship, and performance environments. The design allows integration with compatible Bose Professional electronics and mounting accessories.
