Speaker cabinet materials.

Just wondering what are some of the materials used in building cabinets for speakers? We all know of mdf and solid wood, but how popular is aluminum? Magico and Piega use it. Are there others that use aluminum? And what other materials are used? What about acrylic?
Acoustical wool and mass loaded vinyl is used inside, what else is used?

Green Mountain enclosures are cast using our proprietary Q-Stone (TM). It has a much different formulation than used in our Diamantes from 1993 to 1997. No internal braces are required. It is far more rigid, and with far greater internal damping. And yes, heavy too, which by itself has little effect on the sound.
