Review on Hudson Hi-Fi Silicone Isolation Feet - 4 Pack, Firm Block 150lb Capacity (Non-Adhesive) - Enhance Audio Quality & Stability by Terrance Singletary

I bought four soft kits. I received four tapered square blocks and four round coin shaped blocks as shown in the photo, so I actually received a pack of 8. I used four square blocks on a hardwood subwoofer and they work the way I wanted them to. The blocks are softer than rubber and strong enough to support more than enough weight. They don't have tape, but I think they're designed for that kind of use. It can be a nuisance to change their position when moving the subwoofer, but I might just try double sided tape later if that becomes a problem with cleaning etc. If I never moved it, that would be no. Problem.
