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 bought 2 packs of these products for my subwoofers and my AVR. The pyramid bottoms work great for the subwoofers and the round bottoms were good for the AVR. When you buy it, you get a total of 8 pieces so you can have 2 pieces of equipment isolated which I found to be of great value for the money. Since one of my subs are down firing, the feet really helped here and pronounced the low-end in that one. The AVR is also no longer subject to rattling and shaking when the subs go off which was the main reason for purchase as well, so this product has something to offer for everyone.

Soooooo! Man o man! I have carpet and I have tile! Bose cinemate 15 in carpet sounded muffled, when placed on tile massive rattling and shaking. With Hudson hi fi solid block, amazing! Easy to put on and does it’s job! No rattling no muffle theater like bass man o man!!! Love it thank you!!! Due note no adhesive on these blocks! Don’t buy big isolation pads these do incredible work! Blade runner 2049 maaaaaaaan sooooo goood I’m happy with purchase thanks!

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.

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

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!

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.

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

Darn, these things are very small for over 20 dollars. The blocks are so small they can only be used under a turntable with pointed feet. I placed them under a UTurn Orbit TT that luckily has pointed feet.They made zero difference in reducing vibration/feedback.You also get four very thin nickel sized disks I have not used to date
