Monosaudio-KL 4Pcs Speaker Spikes Floor Protectors Shoes Mats Isolation Stand Foot Base Pads for Audio Turntable Speaker CD AMP (40x10mm)

First - I have not used these yet, so I can't comment on sound quality. They are pretty much what they say they are, a rock-hard disk.I ordered two sets of 4. Out of the sets, several had the divots drilled at different depths/diameters so they did not look exactly alike and will need minor leveling adjustments.The carbon fiber pattern was different among the discs, a bit disturbing if you want them all to match. One pattern was coarse, the other a finer weave.Finally, one of the eight discs was drilled all the way through, so it is useless for my purpose.Still, sucker that I am, I have ordered another set, hoping to find 8 that kind of match each other.Last note, they are cut fairly cleanly but still have somewhat scratchy edges, so I would not use them on a fine surface. I am putting a thin self stick felt velour on mine.

About the size of a nickel. I don’t think they will be effective. My fault for being in a hurry when I bought them.

I’m using these under my heavy Wilson WATT PUPPY speakersThey are solid feeling and a good height to elevate these speakers enough to get them off the floorI believe they sound better than flat on the floor but not as good as the spikesI would like to try them under the spikes but I don’t know if they will handle the weight?I’m satisfied and believe they are good for my purpose

These things actually work. They stopped the vibrations to the subfloor from tower speakers that affected my TT. Good that I tried these first instead of the IA Gaias, way cheaper. Put them under the factory speaker spikes.

Really work...eliminate the harsh tones from higher/treble noise.Get these now!
