Optimized for corner mounting, this 2-pack or metallic copper Vicoustic Super Bass Extreme Ultra VMT features a beige front, and it is designed to provide effective low-frequency absorption between 60 to 125 Hz, delivering maximum effectiveness between 75 and 100 Hz. The VMT front provides sufficient mid-high frequency absorption to control corner reflections. When porous materials such as foam are applied to corners or walls, they become less efficient in dealing with low frequencies, because the particle velocity or air movement associated with long wavelengths is low. However, the sound pressure is at its maximum and Super Bass Extreme's internal membrane transforms these high-pressure fluctuations into air motion. The membrane sympathetically vibrates over a 75 to 100 Hz frequency range, causing the air to pass through a layer of high-density foam that absorbs the low frequencies. Super Bass Extreme Ultra is highly recommended for smaller rooms with low-frequency issues. The panel can be used in different corner positions and its modular structure allows further units to be added as required.
