This 2-pack of matte black Super Bass Extreme Ultra Acoustic Treatment from Vicoustic features an elegant wooden front that is based on Vicoustic's flagship Wavewood panel. Appropriate for corner mounting, it provides effective low-frequency absorption between 60 to 125 Hz, and delivers maximum effectiveness from 75 to 100 Hz. The wooden front panel has two functions, providing sufficient mid- to high-frequency absorption to control corner reflections without deadening the sound.

When the sound pressure is at its maximum, Super Bass Extreme Ultra's internal membrane transforms high-pressure fluctuations into air motion. The membrane sympathetically vibrates over a frequency range of 75 to 100 Hz, causing the air to pass through a layer of high-density foam, absorbing the low frequencies.
