SUBWOOFER ROCK SOLID BASS

PICTURES WILL BE UP SOON IN DETAIL. AS SOON AS I FIND OUT HOW TO POST THEM
AS FOR THE HIGH PITCHED RINGING SOUND THERE ISN'T ANY
IT HAS BEEN TAKEN CARE OF BY INTERNAL BRACING AND TARING
AND STRONG EPOXY GLUE FOR THE JOINTS. THE SOUND IS JUST MIND BLOWING
SOLID DEEP AND ACCURATE NOT TO MENTION THEY WEIGH IN AT 50 kg EACH
 
I'd be interested in what epoxy formula or glue is used for marble, granite or slate. I seem to remember that some have used a specially engineered adhesive formula for these applications, but I may be thinking of something else.

This is certainly interesting as many have used the above mentioned stone for various projects and it would be nice to have some "concrete" information (Boo, Hiss....).
:D

Pictures of the project would be welcome.

Best Regards,
TerryO
 
Here are the pictures.
adding 200g to the P.Rs using hydrojet cuter to open the holes
gluing the sides polishing and adding the bracing taring the interior
and finally adding the drivers and connectors

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!
