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

These insulating feet really solved the problem of replacing the bolts on the Pangea LS400 speaker stands with an alternative suitable for a wooden floor. They fit snugly into the channels at the base of the stands and really stabilize the stands when in place. Using a Home Depot stick on rubber feet, the racks slid. With those HHF feet, the stands really stuck to the ground - and while I don't want to complain about that, I found the bass from the speakers to be tighter and more defined. The repairs were inexpensive and the manufacturer's name was on each leg - no more junk.
