Wow those look really effective, the binding posts look identical to the ones I bought of ebay a months or two ago. How much does all the stone weigh? The only thing I might be concerned about is the little stone legs rattling against the hard floor under hard drive. But if they weight enough this shouldn't be a problem.

A clever person experimenting with box solidity and double-wall construction made a sturdy MDF box and put a driver inside (no holes in box). Said it leaked sound like a sieve. I don't know the physics of playing cone drivers from inside sealed boxes (should it make a lot or a little sound just sitting in a sealed box?) or the psycho-acoustics that lead to declaring something a "sieve" (down 60 dB might still seem leaky?). He later explored using a guitar contact mic. He found roofing tar paper to be a good dampener.

Aside from needing a fork lift truck to move it, this marble box seems to address the rigidity issue in a terminal way!
