Acoustic Geometry Introduces the CornerSorber Bass Absorber

By |


AG-CornerSorber.jpgAcoustic Geometry has introduced a new bass absorber called the CornerSorber. The product uses Mass-Loaded Vinyl (MLV) absorption membranes designed to reduce low-frequency room modes. The CornerSorber measures 24 by 42 inches, with a depth of six inches, and a pair can fit together either horizontally or vertically in the corner of your room. The CornerSorber will be available in a variety of colors and finishes in early 2017.

Acoustic Geometry 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 40 Hz 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!"

Acoustic Geometry's ABM system allows for a high level of low-frequency performance when utilizing both CornerSorbers and Curve Diffusors, which also feature accurately tested low-frequency MLV membrane absorption. The combination has a complementary range of frequencies that produces consistent bass-energy absorption from 50 Hz to 500 Hz. The CornerSorber's form factor of 24" by 42", with a 6" depth, allows both a small footprint and either vertical or horizontal orientation. With the Curve's smooth phase-coherent diffusion, the combination of Curves and CornerSorbers will evenly diffuse frequencies above 500 Hz and evenly control frequencies below 500 Hz, which is the ideal acoustic treatment solution for nearly any room.

This cost-effective system can be used in many applications, including recording and mastering studios, video production and post houses, audiophile listening rooms, home theaters, live-performance and event venues, concert halls and auditoriums. Acoustic Geometry's ABM CornerSorber will also complement any room design. Various finishes are available, including black-stained oak (stock), custom stain and paint colors, several wood veneers (including clear-finish maple, cherry, and walnut), leather and brushed aluminum.

The CornerSorber is set to begin shipping in early 2017.
