1.25" Platinum Silicone Speaker Isolation Pads - 4-Pack Non-Skid Speaker Pads with Adhesive, Speaker Isolation Feet for Record Player Isolation - Turntable Feet and Subwoofer Isolation Pad - 20 Duro

They are large enough to support a pretty stout subwoofer. One self adhesive pad per corner does a good job of isolating and rasing the box off the floor about 3/4 of an inch. They worked well for my needs.

I am absolutely stunned how well these tiny hunks of silicone work. I bought these to pair with my Onkyo C-7070 CD player which would skip when people with heavy feet would walk anywhere near it. I figured if the bumpers didn't work out it wasn't a big deal chucking them at their price point.As a previous reviewer noted the player does wobble a little bit when loading/removing discs which seems a bit odd at first however this is quickly forgotten when playing discs.To test the bumpers I literally shook and hit my audio rack while playing a CD and could not cause the player to skip.Additionally, the sound quality is 100% noticeably clearer in all aspects which is almost beyond rational belief that these little pieces of silicone could introduce such an audible impact but they do!My CD player has never been clearer as the vibrations from my floorstanders are now not effecting the players performance.Highly recommend if your player is sitting still on its stock feet in your set up.Happy listening my friends.

These rubber feet are high enough to stick my sub out of the rug. Great adhesive, 3M is the leader on sticky materials. The rubber seems thick and heavy duty. Pleased with my purchase. Make sure the surface where you expect to use these pads is wide enough to cover their circumference.

They absorb a lot of vibration. I have these on a 12"x12"x12" custom sub with a power 8" tang Band with two 10" Dayton passive radiators.

These bumpers brought about a huge improvement in sound quality when installed in my record player. The only downside is that because they are so soft, the player itself wobbles a bit while opening, closing the dust cover and when placing or removing a record. All in all, it's a good, budget-friendly solution for vibration dampening.

While watching a horror movie I heard my Subwoofer making some nasty Vibrating noise, I did all sort of testing on it to see if I could eliminate it but too no avail, I thought that it had blown and I had to shell out for repair/replacement, then i read that Vibration from the foot pads could've be the problem. While my sub did have dampeners they were very thin and hard rubber. So I bought these babies and with a dash of hope I put these on and Voilà! the irritating vibration is gone and now just pure sweet rumble. A Stress test on max output and No issue at all. Wholeheartedly Recommend.

In an effort to reduce some vibrations that are transferred to the LP player's cartridge, I bought a set of these Hudson Hi-Fi Silicone Hemisphere Bumper/Isolation Feet. These are easy to install, and have some excellent adhesion via 3M - just peel and stick. These feet could be used in a variety of situations on other components, but I wanted to try these on my Audio-Technica turntable.One thing I would say: measure first. They do offer several sizes and purchased the 1.25in set but I did not measure first. These are a little too small for my turntable but they are constructed very solidly. Also, my turntable feet 'float' a bit and swivel, so the small feet did not suit this setup as ideally as it could have. That was my fault. Being that the silicone feet are rounded, and a little too small, my turntable was moving around and not setting properly. I may try the larger size - better yet, if they were flat, it would work better in my situation.I believe these are engineered with the rounded ends such that there is minimal contact between it and the secondary surface. It is another well thought-out and high quality product from the designers at Hudson Hi-Fi. Be sure to measure the area that you want to modify and your results will be optimal.

Works great on an alternative use. I used them to eliminate vibration noise from my dresser backboard. They have flimsy boards on the backs of dressers, and normally they don't make noise, but I have wood floors with an area rug, so 2 legs of dresser are on rug, and 2 are on floor. Even with cardboard squares on floor to level the height of floor with rug, it rattled every step I took (which was crazy annoying and driving me mad).So I got these. Be aware that it's not 1.25" of height, but 1.25" of diameter. 'Hemisphere' is vague. I have to pin it against the wall until the bumpers touch the wall. Maybe I should have bought the Big Foot, but I don't want to spend an extra $13. It works, no sound.
