Description
Bose Professional DesignMax DM8C-SUB In-Ceiling Subwoofer (Black)
Bose Professional DesignMax DM8C-SUB is a subwoofer designed for indoor commercial audio installations. It enables low-frequency reinforcement for system designers and integrators, supporting full-range DesignMax loudspeaker systems. This makes it ideal for spaces where controlled, consistent bass performance is required.
The subwoofer operates with an in-ceiling design using an integrated backcan and an 8-inch low-frequency driver. It supports both low-impedance operation and 70V or 100V distributed systems with selectable transformer taps. Installation is performed using the QuickHold mounting system for ceiling applications.
The system supports applications that require extended low-frequency response in distributed audio environments. It is suited for venues such as retail, hospitality, worship, and performance spaces. The design allows integration with compatible Bose Professional electronics and loudspeaker systems.
