As any physicist knows, no device, no matter how clever or sophisticated, can eliminate energy. It can only convert undesirable energy into a more benign force. This applies to unwanted vibrations that hamper the fidelity of both transducers (such as analog playback devices) and electronics (which are susceptible to vibration-induced microphonics).
With this understanding, Wilson Audio’s Special Application Engineering team has always approached the problem of vibration mitigation from a scientific perspective. When designing its new isolation device, the WASAE team leveraged Wilson’s industry-leading measurement capabilities, which have evolved continuously from their perennial quest for the best solutions for ultra-low resonance speaker enclosures.
The Pedestal reduces musically destructive vibrations systematically. Its small bottom element partially absorbs vibrations traveling from the surface underneath the piece of equipment. Next, energy migrates into the Pedestal’s austenitic (non-magnetic) stainless-steel housing, where the material’s mass and solidity further turn unwanted energy into heat. Where other manufacturers use low-grade magnetic steel in their isolation pods, Wilson is committed to metals that have superior vibration-mitigating characteristics as well as the ability to minimize electronic interactions of the components which the Pedestals support.
The damping material inside of the Pedestal—“V-Material”—provides the next step in vibration reduction. V-Material, along with a proprietary viscous damping material inside the Pedestal, act as a spring to minimize, absorb, and dissipate the vibrations into heat. When weight is applied to the Pedestal, the internal V-Material element, along with the other critical elements within the housing, are decoupled from the stainless steel exterior.
From the reverse direction, from the component on down, any vibrations caused by environmental factors or from the audio system itself, travel into the top pad of the Pedestal, where they are reduced. From there, any remaining vibrations are guided directly to the V-Material where they are effectively absorbed and dissipated as heat.
Low-frequency, high-amplitude vibrations, such as those generated by footfalls, are reduced via the spring-like action of the V-Material and damping material combination.
