The Wilson Audio R&D team has spent the past few years developing their latest advancement in vibration mitigation, the Wilson Audio Acoustic Diode. The Acoustic Diode Spike was launched with Alexx V and initially has only been available with the purchase of Alexx V.
We are excited to announce that you can now upgrade your current Wilson Audio loudspeaker Spike Assembly to the new Acoustic Diode system.
Current thread sizes available: 1/2" - 13 (all current Wilson Audio Speakers) and 3/8" - 16 (most retired Wilson Audio speakers). More thread size options to accommodate a variety of loudspeaker brands coming in Q3 2021.
The Wilson Audio Acoustic Diode ™
The Wilson Audio Special Engineering® (WASAE) Team has always approached the challenge of vibration from a scientific perspective. Once the science surrounding the elements to be deployed is acutely understood, the art of the project can begin.
While designing the Pedestal®, a very effective tool used under audio equipment, the objective of this device was to isolate the equipment chassis from vibrations entering the gear from the surface it's installed on.
Wilson Audio has successfully employed extremely precise laser vibrometer testing equipment for well over a decade and a variety of other analysis systems previous to these tools. Valuable data collected from this equipment during dozens of product development cycles, including the R&D of Pedestal, gave the WASAE Team greater insights into the complexities of vibration management under loudspeakers. Putting to use their industry-leading understanding and material measurement database, the Team set the lofty goal of improving upon an element of the loudspeaker that traditionally has been very good for Wilson Audio.
Loudspeakers interact with their environment in two primary ways. First, with pressure originating from the driver's diaphragm and second, the vibrations directed into the floor from the enclosure through the speaker's footers, or "spikes". The first is what audiophiles and music lovers hope to experience in its most powerful, engagingly elegant, and intimately emotional ways when their system is turned on. The second is the area of exploration, and the primary focus, of this amazingly functional Acoustic Diode system.
An improved spike system would have to minimize vibration from the enclosure going into the ground while simultaneously diminishing unwanted vibrations from being transmitted up into the enclosure. We have seen and scrutinized many ways the interface of loudspeakers to the floor are addressed. Many companies simply develop spikes to isolate the loudspeaker from the floor. These methods with elastomeric materials, ceramic bearings, and a wide variety of other designs can allow the loudspeaker to move in parallel with the drivers. Unfortunately, these micromovements can sonically present themselves as smearing, colorations and various forms of distortion during playback. These artifacts can add an effect to the music that may be initially interesting and possibly exciting. The reality, however, is that the fidelity of the recording has been altered.
To remedy this, direct coupling to the floor is needed while, at the same time, not providing an easy path for vibrations to be injected into the ground.
Building upon the research and developments of Pedestal, the Special Applications Engineering Team is excited to announce the Wilson Audio Acoustic Diode (AD Spike for short) At the heart of the Acoustic Diode is our proprietary "V-Material." This superior constrained layer damping composite is unsurpassed in vibration absorption and resonance control.
Energy from the enclosure migrates into the V-Material where it is faced with the effective damping properties of this efficient material. The mass of the loudspeaker concentrated onto the very small ends of the spike tips result in significant levels of PSI that prevent detrimental vibrations from travelling upward into the footer. Those vibrations that do travel up the spike are absorbed by the mass of the Acoustic Diode and have to travel through the V-Material to have a chance to influence the enclosure. Keeping the spike and threaded post separate prevent a direct path for vibrations to travel, or interplay, and are therefore dissipated and absorbed in either the V-Material or the footer housing.
The distinctive design, combined with advanced vibration-mitigating materials, provides the best of both worlds; a solid base from which the drivers can launch as well as preventing the transmission of energy from the floor to the loudspeakers.
Separation in the Assembly
A machined V-Material insert is inset into the robust austenitic stainless-steel diode housing. A stainless-steel post is then threaded into this exclusive V-Material, never touching the diode component. On the bottom of the diode, a spike is threaded into the diode housing, but it does not couple the V-Material insert. Once the Acoustic Diodes are installed into the loudspeaker, only the V-Material section of the diode comes in contact with the bottom of the loudspeaker.
"The new Wilson Acoustic Diode isn't an optional device; it's an essential one. It dramatically lowers the noise floor, both boosting dynamics and revealing previously obscure musical details." - Jacob Heilbrunn \ The Absolute Sound
