Bose DesignMax DM8C-SUB In-Ceiling Subwoofer, White

The Bose DesignMax DM8C-SUB White is a high-performance in-ceiling subwoofer built for commercial audio installations that require discreet yet powerful bass. With an 8-inch woofer, 180 watts of continuous power, and plenum-rated construction, it delivers low-end punch while maintaining clean ceiling lines.

This model supports 8-ohm low-impedance systems and installs easily using QuickHold mounting arms. It is designed to complement other DesignMax ceiling speakers in system-wide installations across retail, hospitality, or corporate environments.
