Sound Addicted SubCone Isolation Feet - Improve Subwoofer and Speaker Performance, can Sustain up to 165lb (4-Pack) Non-Adhesive

I used it for my Klipsch Promedia 2.1 Subwoofer, and it completely changed the base quality(in a good way!) The feet can be a little awkward to place, but I appreciate the non-adhesive style for future resale value with the potential to damage the finish of the sub. Before I added these feet, the Klipsch had a very distinct BOOM to the base. Most reviews describe it as too boomy, and I agree. With these feet, however, the boominess is completely gone, and the base lows are significantly cleaner and all rattling is removed.

I used these to lift my CD changer off the countertop. I placed one under each of the feet on the player and it works great. Well made, sturdy with just enough give. Now I don't have to stretch as much to reach, and it doesn't skip nearly as much walking on my hard floors! Highly recommended.

Very good product well made and works well

Well made but tough to mount as they are made of silicone, will support a heavy speaker no problem. Old time Duco was able to stick them, two sided tape didn't adhere at all.

I was just about ready to throw away my rel subwoofer that I had paid about $600 for. The base feet are hard and I was hearing a buzzing or humming distortion sound whenever the movie base was very low or strong. I started looking for any remedy that might help with those issues. People were suggesting foam or rubber pads that would allow a realistic, full base without any humming distortion. I looked at these pads and after reading the reviews decided to try them. The results are fantastic! I'm getting all the expected performance out of the subwoofer without any humming or buzzing issues. Give them a try, you'll be pleased with the difference.

These are fantastic when coupled with DGJM 50PCS Double Sided Adhesive Pads for Mounting, 2-3/8inch Two Sided Pre-Cut Square Tape. The two-sided adhesive works perfectly with these heavy duty rubber feet. I purchased a very heavy and expensive Velodyne (used) that did not come with feet. These are more than capable of supporting its weight. I applied the adhesive tape squares first. I would not even call this "tape." There is good thickness to the adhesive. And it's potent. I flipped the subwoofer so the bottom side was up. Use good pressure between the feet and the cabinet to get a good bond. I put my weight into it. These are absolutely excellent when used with the above adhesive. Absolutely met my expectations.

I wanted to raise my center channel about an inch and these did the job perfectly. Can't speak for their sound isolation properties, but they feel extremely solid, well designed, and use high quality materials. I'll try these on my subwoofers some day.

These made my speakers too unstable due to the narrowness and height of the speakers. I think with threaded inserts or attaching with an adhesive, who make these feet more universal and useable. Unfortunately, due to the materials used to make the feet, no adhesive will stick to them.

No more neighbours complaining, makes a sound stay in place. It enhances the base to this proper levels.
