BXI - Anti Vibration Isolation Pads - 6 X 6 X 2 inches 2 Pack Rubber & Cork Pad - Thick & Heavy - Excellent at Low Frequencies, Great Acoustic Isolation for Speakers, Washers, Machines, etc

This worked awesome with my modded and heavy ESS AMT3's-now weighing 130+ lbs. Located on a wood floor this cleaned up the bass perfectly. Expensive, but much less then audio specific units-and very effective-thanks!!FIY-I got the idea from a Stereophile review of Klipsch Forte III speakers, were the reviewer was experiencing similar muddy/boomy bass issues.I tried rubber pads/ felt pads, wood blocks etc. Nothing worked well till I tried these.A excellent product and great value, using proven, simple and effective materials and construction.Thanks guys for a great product!!P.S.-Unlike Stereophile_I used 4 per speaker. First to keep the speakers better balanced-plus my speakers are quite a bit heaver then the Klipsch Forte III's.So I would say may sure weight of your product you need to isolate, and balance is taken into consideration.

I put it under my speakers in my studio, they worked good. if they made a big one it would make a great gobo or bass trap! They do have a strong chemical smell when you unwrap them.

I live in a solar powered off-grid cabin with a 2,650 gallon cistern for water, which is up-hill from the cabin but not high enough to provide reasonable pressure so I have a 24VDC water pressure pump inside the cabin to maintain an even 60PSI to all water fixtures.I tried mounting the pump directly to the wall but the wall acted as a sounding board that amplified the noise of the pump. Searching Amazon, I found this BXI Soundproof Tile - Anti-Vibration Pad - Isolator. I re-mounted the pump on the pad and much to my hopeful expectation, the pad isolates the vibration of the pump from the wall quite well. It is now much more quiet.

These blocks work very well for me. I have placed them under a pre-amp to my stereo for the turntable. These do soak up any vibration and provide a firm base for this sensitive electronic unit. Just great and I already have plans to order another pack. Do not put these under a washing machine!

Works like a charmSolid isolationPerfect for any Hi-Fi enthusiast looking to control vibration, extend bass, and overall isolate componentsPerfect

Slightly softer and these would completely knock out the vibration. They took care of of maybe 40-50% of the vibration. If I put a piece of 2” foam under these, it blocks 90%. Maybe a two part design would be better...

I really love the way they absorb the shock. I do not have a large home so I have washer, dryer and over next to each other. I would do the wash before and it would shake everything. Now you feel the shake alittle and my over does not move at all.

Excellent product. Placed these under my generator (which is housed on the second floor of my garage) and it reduced the noise and vibration below, considerably. Definitely recommend.
