Selecting EVPs

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 will compress some, but not fully, allowing the equipment to float. When properly loaded, the EVP will evenly compress about 10 – 30%. Following the steps will insure proper deflection and performance.

STEPS:

  1. Determine the weight of the equipment to isolate
  2. Enter weight into EVP Calculator (below) and select Pounds or Kilograms.
  3. Decide on 2 INCH or 4 INCH square EVP.
  4. Decide on number of EVPs (3, 4 or 5)
  5. Determine proper EVP density (LOW, MEDIUM, HIGH)
  6. Choose between RUBBER OR FELT.
  7. Place order


As with all our products, there are third party standard test measurements backing the claims, along with a 30 day money back guarantee (in original condition) if not satisfied.

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.
