The Secrets are 40 x 3 mm discs made of extremely energy-absorbing material. They are used to dampen vibration energy on the surface of components. The damping can be varied by placing one or more Secrets on a component or loudspeaker. This allows optimization of the tonal balance and dynamic performance of the system. Secrets housing dampers are an integral part of the AntiSpike component feet and produce an even greater effect when so used.
