Multi-Media & Rec Room

Acoustic Geometry’s CornerSorber is a corner-placement bass absorber utilizing a Mass-Loaded Vinyl (MLV) absorption membrane in a cutting-edge design that mitigates low-frequency room modes for the most accurate sound reproduction in a room. The CornerSorber is the only laboratory-proven bass absorber design that achieves maximum pressure-zone room-mode reduction due to close-corner placement. The uniquely-shaped bass absorber is beveled on two sides and the top, allowing a pair of CornerSorbers to be set up three inches from, and parallel with, each corner wall, either vertically or horizontally, for the most efficient and effective reduction of low-frequency room-mode pressure waves. In developing the CornerSorber, our design goal was to build an affordable, easy-to-use solution that would realistically reduce destructive low-frequency room modes. We wanted to avoid claiming product attributes that were not accurately tested in large enough facilities or with real-use positioning. We tested the CornerSorbers at NWAA Labs because their test chamber is the largest in the U.S., and accurately measures absorption down to 40Hz (per ASTM C423-09a). We also tested the products in their real-use mounting configuration, which is deep into ninety-degree corners. The test results prove that this close-corner location makes the CornerSorber a very efficient and effective low-frequency absorber. CornerSobers are priced at $799.98 per PAIR (plus shipping), and are available through our retail dealers and direct from our online store. Black is standard, other finish options are available.
