I need to raise my M60's about 4-5 inches. I have a wood suspended floor. I plan on making bases the shape of the speakers out of 1" high density MDF. I thought three layers thick with the middle cut out and filled with modeling clay, then veneered and painted. Under the stand I want to use Herbies "Big fat dots. Under the speakers I'll switch to the spikes that came with the speakers. Anyone have anything under their speakers already that sounds good? This is my first post so any input will be awesome!
