Block Silicone Isolation Feet - 4-Pack Subwoofer Isolation Pad w/ 37.5 lbs Capacity - Pads for Small Speakers, Speaker Spikes & Turntable Isolation Pads for Reduced Vibration & Resonance

I wanted something to ensure the percussive nature of a subwoofer stayed local to the space its in. These do that. My woofer is nice and punchy in my listening space, doesnt rattle anything, yet out side of the room its audible. You can hear it, but you cant feel it at all, which is awesome. The fact theyre little feet, as opposed to a while pad gives maximum flexibility in what you use them for, plus, they sent me some cute little minis!

These work, but make sure you understand the measurements before you purchase. For subwoofers on carpet these would not have an effect. I used them to stack two identical subs on top of each other and they are great for that. Also, they could be used for components lacking feet.The challenge is that they do not come with adhesive. If you plan on keeping the item placed on this in the same spot for a long time and can drop it on top, no big deal, but if you want to slide a large component on top of these, it is basically impossible as they don't have adhesive. They are solidly built just know what you are getting and the size.

I have a budget hifi system. For those of you guys who are aren't familiar with hifi/audiophile systems...budget still means quite a few dimes. I cant say about improvement because it worked out to where I'm setting everything up at once. I needed to separate my intergrated and power amplifier that I have stacked and to put something between the amplifier and shelf. Bought 4 sets. Using the other two for my turntable and cutting board. Figure since I have a pair of down firing subs...i should have something there for my gear. People have mentioned Herbies and wither or not these are knockoffs... I have no idea... but these seem to be doing their job and are apparently made with the same material as Herbies. Unless there's a secret to making things out of silicone then I dont see why these can't be legit for half the cost. Time will tell...but I have yet to notice vibrations distorting my sound using these. Guess if you have the money for Herbies...go for it..I mean why not. But I'm using the money saved for another power cord :p

Was a little too small for my application… Not the products fault

Fantastic product. I was hoping my sound Bose sound bar would be even better with these. I’m hard of hearing and getting the sound bar 3/4 of an inch away from the shelf cleared the sound right up. Also attached the thin round ones under my lap top to have more cooling while on my desk. I’m gonna be ordering many more of these since the usage is unlimited.

does not come with any type of mounty adhesivehad to buy double sided tape to secure to sub wooferadditional expense!

I bought this to eliminate my turntable skipping as I walked by. I used the small coins under the turntable with little effect. Then I took the larger pyramids and added them under the table holding the amp and turntable. There was quite an improvement but not 100%. I don’t have to tiptoe but I don’t think it will help when the grandkids come barreling through the house

Excellent product. These are used on a 23 lb. Subwoofer that did move dishes and other items around in the cabinet. Since I put these under the legs it absolutely stopped it. No vibration transfer at all.
