Discreet In-Ceiling Design

Designed for complete visual discretion, the DM8C-SUB installs flush into the ceiling, with a paintable grille that allows it to blend into any decor. This makes it the perfect choice for architecturally sensitive spaces like high-end retail stores, restaurants, and hotel lobbies where premium sound is required without visual intrusion.

It uses the Bose QuickHold mounting system, which features spring-loaded arms that make installation fast and easy for professional installers.
