I can't remember which article it was, but it must have been from one of these threads http://theartofsound.net/forum/searc...earchid=795249

Cheers.

I don't think they need to be as thick, or as dense, as the commercially available ones.

You can make your own very neatly.

Kind of reminds me of the Acoustic Blanket used on the early Acoustic Research loudspeakers, though as you point out - not as thick ;)

Jim made quite a few posts but this was the first one that talked about his products, I think.

They are clad with a particularly high fired porcelain tile. In this case the tile is not glazed at all (it is post production polished - like stone). The whole thing is the same colour, and material, all the way through. It is fired to a very high temperature that essentially vitrifies the material and results in an extremely stiff ceramic panel. It has been glued to the sides with a particular flexible adhesive intended for use where wooden flexible floors must be tiled. Essentially, their application creates a constrained layer structure. The flash makes them look quite a bit paler than they really are (they look nearly black in real life). They had to be cut with a diamond saw and the edges were polished by a local company that makes mirrors.
