Granite under your amp???

pads to protect the wood floor. The spikes are in direct contact with the granite. I removed the two front outside spikes (only use 3) that way they are all load bearing and they are all making full contact. (also it is easier to adjust the tilt (front to back) to match my seating position. No vibrations what so ever.

thick 24inch x 24inch on a side with beveled edges. cost abt 500 bucks for 2 (edges were expensive) they weighg abt 50 lbs+ each. But my ml requests now have a nice base that keeps the spikes from going through the floor.
