    These 2" x 2"x 7/8" isolators are for sale at Amazon for less than $10 for a package of four. I wonder how much different they are. By the way, I use the 4" x 4" under my turntable and they do damp the vibration from the equipment rack.

    DiversiTech MP2-E E.V.A. Anti-Vibration Pad, 2" x 2" x 7/8" , Pack of 4
    They look similar, but the DiversiTech pads are for heavy machinery and made of foam or cork, where EVPs are made of layers of glass fibers working as leaf springs. If you look at the DiversiTech information you'll find that they for machinery starting at 50 psi, so for four 2" pads your equipment needs to weigh about 400 lbs, and four of the 4" would mean 800 lbs. They don't publish minimum loads, and in order for isolation pads to function, they need to be loaded properly- too much or too little weight and they don't isolate. EVPs are designed specifically for audio equipment- meaning that they control vibrations from sub through the audible bandwidth, and their resonant frequency is below the audio spectrum (actually about 3 Hz.). DiversiTech doesn't publish any lab tests, but if they did, you'd likely find resonant frequencies in the audible spectrum, which is not a good thing for noise control or sound quality.

    I just put the 2” x 2” isolators bought from Amazon under my speakers and they work great. I put 4 isolators under each speaker. A less than $13 tweak that works great. That’s what I call good value.
