Isolate It: Sorbothane Vibration Isolation Circular Disc Pad .5" (1.27cm) Thick x 2.5" (6.35cm) Dia. 70 Duro - 4 Pack

I placed this behind the mounting bracket of a dart board at home and it reduced the vibration (noise) from the dart board by a significant amount. Sound no longer carries through the rest of the house. Great product.

I'm always skeptical of these products and their claims, especially in the audiophile world where you can imagine buying audiophile air in a can to improve transparency, depth, and dynamics in the music you're listening to. Just a few spray's into your listening environment and you can transform your system in ways you can't imagine.These actually ended up working quite well, I'm using them under subwoofers that we're causing a vibrations throughout the room / walls at specific frequencies. This is a wood floor so I put these onto floor sliders first (hard plastic/felt bottom) to prevent staining the wooden floor overtime as lots of reviews have complained about. While they didn't improve any dynamics or anything that I can tell my rattles/room vibrations are gone so they did something at least and for that 5 stars!

I'm quite disappointed by this purchase. I bought the disc pads to help with the vibration of my portable air conditionner unit and my downstairs neighbour tells me it didn't really help. A tad expansive for a solution that doesn't really work... :(

High-quality pads with no-nonsense protective packaging. Excellent vibration solution for subwoofer platform or similar.This is basically raw sorbothane so plan to distribute weight evenly on the surface; this isn't a product on top of which you should put appliance feet, or oddly-shaped/smaller-diameter, feet. Like any other part, it needs to be used correctly to support the manufacturer's claimed resistance

Works exactly as advertised.I use these to absorb vibrations from a subwoofer to monitor speaker stands. It reduced them ~60-70%
