Dynamat 50306 DYNABOX In-Ceiling Speaker Box for Home Theater Audio Soundproof

Elevate the performance of in-ceiling speakers
In-ceiling speakers are an excellent option for a stealthy music or home theater system. But much of the sound they produce can end up leaking into the room above. A good solution for this is the Dynamat DynaBox.

This flexible foam enclosure helps an in-ceiling speaker deliver focused. well-balanced sound in your listening space while reducing audio bleed-through to the adjacent room. You’ll get more sound where you want it. and less noise and vibration where you don’t.

How it works

The DynaBox is made of flexible vinyl that allows it to be collapsed for retrofit installation. You actually fold the enclosure and push it up through the hole you’ve cut in the ceiling for your speaker. Once the box is in place. line it with the two supplied sound absorbers: the SoundSnake acoustic decoupler. and Back-wave foam panel. 

Of course. the DynaBox works great for new construction. too. Click on the Details tab for step-by-step installation instructions.
