Acoustic Geometry™, a company offering best-in-class acoustic products for a wide range of professional audio, residential and business applications, is excited to announce the newest addition to its Acoustic Bass Management (ABM) product line, the CornerSorber™. These corner bass absorbers utilize Mass-Loaded Vinyl (MLV) absorption membranes in a cutting-edge design that mitigates low-frequency room modes for the most accurate sound reproduction in a room.

Created by John Calder and Mark Stender of Acoustic Geometry, the ABM CornerSorber is the only laboratory-proven bass absorber design that allows 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 give customers an affordable, easy-to-use solution that would realistically reduce destructive low-frequency room modes," says Calder. "We also 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. Their test chamber is the largest in the U.S., and accurately measures absorption down to 40Hz per ASTM C423. We also tested the products where they'll be located in audio rooms, which is deep into ninety-degree corners. The test results show that this close-corner setup creates a very efficient and effective low-frequency absorber. Needless to say, we're very happy with the results!"
