Dynaudio’s Sub RCC is a compact in wall or in ceiling subwoofer. Designed to be flexible and simple to install with no additional backboxes or drywall reinforcement required, the reaction cancelling design means that very little vibration is transferred to the mounting surface. The sub is supplied with two mounting options, the retro fit chassis allows for installing into a pre-existing drywall surface. The pre-con mounting brackets mean you can mount directly to the wall studs before the drywall goes up, resulting in a smaller aperture and grille finish.
