Articulation is improved because mechanical energy can no longer introduce vibrations into the building structure, microphonics to tube electronics and cables, mistracking of phono stylus and laser beam, digital clocks, loudspeakers and microphones, connections, etc. Elimination of feedback loops, ringing, and resonances means your system becomes an improved, more enjoyable version of itself.
IMPROVES SOUND QUALITY
Clarity, Dynamics, Timbre and Soundstage are improved because resonances and vibrations are eliminated from the electronics, the loudspeakers, and the building structure.
REDUCES SOUND TRANSMISSION
Vibrations are not transferred to the building structure for others to hear. In addition, the listening space no longer rings of resonances, and buzzes and rattles cease.
LAB TESTED
Found to conservatively eliminate vibrations to and from equipment from 5 Hz. and above, by >90%. Standard EVPs have a natural frequency of 3-4Hz. in the specified operating load range.
DIFFERENT SIZES FOR DIFFERENT JOBS
Too little or too much deflection will not decouple energy transfer. EVPs come in 3 densities and 2 sizes to “float” the weight of your equipment properly.Custom EVPs are also available.
CHOOSE THE RIGHT EVPs FOR YOUR EQUIPMENT
Too little or too much pad deflection will not work to decouple energy transfer. When the equipment weight is properly loading the EVP, the pads compress some, but not fully, allowing the equipment to float. When properly loaded, the EVP will evenly compress by about 10 – 30%.
2” vs. 4”: Generally 4” EVPs should be selected for subwoofers and full-range speakers (offering more material to do more work), and/or when you need the stability, or the load handling. 2” EVPs work for most electronics. More than four EVPs can be utilized.
Different Density Options: When given the option, select the higher density EVP, only because they are less fragile while offering the same performance.
Rubber vs. Felt Finish: Same performance. Generally, select rubber when you don’t want it to move, i.e. under floor standing loudspeakers or a guitar amplifier. Note- rubber finish is taller than felt. Select felt when the equipment will be resting on a smooth surface of some kind, allowing you to easily slide it into position without scratching the surface.

NEW EVP PLATFORMS!
EVP Platforms are for speakers and electronics and perform just as the regular EVPs do. Use one pair of EVP Platforms per component. They can run front to rear or side to side. This makes them a very universal fit. EVP Platforms have the same performance characteristics as regular EVPs, but offer better stabilization, easier installation, and an elegant look. They are typically finished with #4 brushed Stainless Steel with options of black felt and wraps of vinyl leather, marble, or carbon fiber for a small upcharge.
EVP Platforms can also be made with custom dimensions, densities, vinyl wraps, and core colors. Contact us for more information.
HOW DO THEY WORK?
EVPs are vibration isolation feet for high-fidelity playback and recording equipment, as well as guitar, bass, and keyboard cabinets, microphone stands, etc. EVPs allow equipment to perform optimally, quiet the room, and prevent vibrations from being transmitted to adjoining spaces. Vibrations and resonances are no longer heard, leaving only the pure original signals. Vibration transfer is a two-way street; vibrations can travel both to and from a source, and/or be reflected back to the source.
Improves Sound Quality (clarity, dynamics, timbre, and soundstage) because resonances and vibrations are eliminated. Floors, walls, ceilings, and furnishings cause unwanted resonances and vibrations to be re-radiated into the room. Vibrations can even cause sonic degradation in electronic components, their connections, laser reading, and turntable playback, resulting in data corruption, phase distortions, noise, etc.
Microphony occurs when electrical components receive mechanical energy and convert it into electrical energy, thus distorting the signal. Tubes and phono cartridges are especially susceptible. Crystal oscillators in digital products can be affected by vibrations by changing their frequency slightly, causing timing errors. Turntables are certainly the most sensitive to vibrations, amplifying them over the speakers, sometimes even to the point of feedback. They are also most sensitive to footfalls being picked up and amplified and even mistracking. Some speakers are sensitive to the movement of even a single micron. Loudspeaker cabinets can easily vibrate well above this and influence the response.
Improves Noise Control by reducing Sound Transmission to adjacent spaces. This relieves other occupants from being annoyed, as vibrations are no longer transmitted into the building structure.
EVPs have been lab tested and found to conservatively eliminate vibrations to and from equipment from about 5 Hz. and up, by >90%. This is done by converting mechanical energy into thermal energy. The result is audible from both sound quality and a noise control point of view.
In addition, solid feet offer little to no noise control, rather they transfer vibrations directly into the structure and to adjacent spaces by coupling them. This structure-borne energy is not only transferred to connected spaces but also re-radiated back into the room. The videos below demonstrate the EVP effectiveness in an easy-to-understand manner. It also demonstrates how solid feet do not isolate vibrations, rather they directly couple them, attenuating some frequencies while amplifying others, depending on the unique compliance of the whole system. The mechanically plucked tines offer a controlled, repeatable demonstration. EVP offers a neutral, repeatable and predictable solution.
Coupling vs. Decoupling:
To isolate means to decouple. EVPs decouple and “float” resting equipment while absorbing vibration energy. A proper decoupler must be able to handle the load without compressing too little, or too much, in order to function. EVPs have no natural resonant frequencies in the audible bandwidth. They will even mitigate subsonic frequencies where footfalls and feedback can present problems.
Spikes, blocks, and cones are couplers. They act as filters by attenuating some vibrations and amplifying others. Always unique and never neutral. A different sound doesn’t always mean it’s better. Hard feet couple vibrations to whatever they are touching. Think of a tuning fork handle placed against a shelf. The shelf becomes a soundboard. Rubber-type pads are limited in bandwidth and in load handling. They too alter the sound but do not eliminate the problem. Decoupling is the correct solution to preventing vibration transmission and removing resonances.
