Marble to place speakers on?


I remember reading a thread pertaining to placing your speakers on a marble surface. Up to this point I have been unable to find this thread on the audiogon site. So I am going to ask the question again. What should the demensions of my marble be? Height, Width, Depth, and Thickness. I appreciate your time.

If I do bolt the speakers to the marble, am I doing away with spikes all togather hence adding mobility by sliding?
