Regarding purchasing your piece of marble. My wife suggested going to a cooking or kitchenware store. They supply marble for pastry rolling and it's very inexpensive. You can then cut to size with a tile cutter. Just a thought to save you money.
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.
