Review on Zerone 30X20Mm Rubber Guitar Anti Vibration by Brandon Woodson

I wish the rubber was stiffer, bigger and a bit higher but for the price you can't beat it. Came with screws but they are too small. I used my own to raise the subwoofer box off the floor for my own theater with 2 x 15" 800 RMS audio tubes and run them with a 1502 crown :) Two subwoofers, more cost effective than buying expensive active subwoofers .my walls and windows and chimney are shaking!basically the whole house
