I have tried 3 versus 4 feet under everything for years and in every case, 3 feet always sounded better. I have written a computer program for the optimum placement of 3 feet under any component. I just need the left-right width and front-back depth and the diameter of the cone/foot. The chassis must be reasonably rigid and not overly weighted on one side. Send me some measurements and try it out. The results of the calculations have been with a few mm of perfect for practically every component I have tried, even heavy power amps. If the feet are too close to the edge, the sound becomes tight and restricted. If the cones are too far underneath, the sound is loose and a bit out of control.

Most cones come in sets of three but some also come in sets of four . Whats the lowdown on cones I am thinkg of trying tem under my speakers and CD player . Thanks for your time!
