Axxess Noir resonance control devices (Set of 4) Axxess Noir resonance control devices absorb vibrations that are not directly related to the signal path. The absorption results in an audible vibration feedback, which affects the sound quality. The Axxess Noir device is made from a special mineral-filled composite material that preserves the music signal. These resonance control devices enhance the listening experience by minimizing unwanted vibrations, allowing listeners to fully immerse themselves in the music. The Axxess Noir consist of 3 discs. Each of the top two discs floats on three titanium balls, to ensure excellent handling and absorption of sound vibrations. Ansuz Acoustic products provide the foundation that can greatly enhance the performance of any audio system. Our line of products consists of high-end cables, power distributors, streaming assessors and resonance controlling devices.
