Improving the sound quality of your in-ceiling speakers and stopping noise transfer to other rooms is the goal of all pro-audio enthusiasts. While speaker quality is high on the priority list, so is the placement and proper installation of speakers. One item to consider when installing your in-ceiling speakers is DynaBox -- a retrofitting ceiling speaker enclosure from Dynamic Control. Designed for both new and existing home theaters, DynoBox isolates vibration and noise so it doesnt migrate to other rooms -- resulting in pure, high-quality sound with limited collateral disturbance.

When you install a speaker in a ceiling, noise from the back of the speaker travels throughout the ceiling channel and resonates through floors and walls. Not only does this create unwanted noise in other rooms, but the speaker also loses significant sound quality. With DynaBox, the noise and distortion from the back of the speaker is absorbed, enabling the speaker to project the highest quality sound into the room.

The system is made from a one-pound-per-square-foot flexible vinyl sound barrier and a triple-layered acoustic coupler called the sound snake, along with ultra-high efficiency acoustic foam. This combination creates an acoustic vault that completely encases the back of the speaker and performs like a well-crafted solid speaker cabinet.

For the best in professional home audio, install DynaBox with every in-ceiling speaker
