Combines an acoustic foam absorption panel with specially engineered air cavities to yield extraordinary sonic benefits. The VersaTile design allows it to be used in a variety of ways. It can be positioned to bridge a corner, creating a sizable air pocket that gives you some great low-frequency absorption. It can also be placed on walls and ceilings with either side out, allowing for some sophisticated looks while offering superior absorption characteristics versus thinner, flat acoustic foam panels. 6 panels cover 16 square feet.
