Acoustic Soffit

With hundreds of hours of real world testing, ASC’s engineering and product development technicians have produced the best acoustical soffit available anywhere. Acoustic engineers have known for hundreds of years that a soffit is an excellent sound diffuser. ASC improved the idea to include absorption and custom room tuning.

Acoustic Soffit

When only the best will do, discriminating home theater builders insist on ASC’s Acoustical Soffit System as part of their acoustic treatment package. This is a custom engineered product, sized specifically to make a room sound it’s best. ASC takes all the guesswork out of the equation by running the calculations necessary for the perfect balance of absorption/diffusion. In a nutshell, you will hear much more sonic detail produced by your speakers, instead of fuzzy echoes. Plus, the soffit can be part of the existing architecture, or not, depending on your desire. The ASC Acoustic Soffit is a one-stop acoustic treatment that in many cases will be all you need.
