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?

I have been considering building some isolation platforms and devices out of a material that my company uses in our products for vibration dampening. The product that we use is a special steel that is comprised of one layer of 12 gauge steel, a layer of a dampening polymer and another layer of 12 gauge steel, heat/pressure laminated. Our supplier can provide this to us using Stainless steel on the outsides or cold roll steel, with a wide range of gauges. The affect on our equipment is a significant reduction in noise levels by eliminating vibration of moderate expanses of what would otherwise be ringing sheet steel.

Even with sections as large as 2.5 feet X 4 feet (10 square feet) the sound is virtually dead with a knuckle wrap on the sheets' center point. Certainly as dead as a similar knuckle wrap on my Wilson speakers.

We got this idea from BMW, they used this same material, that we have made here in the States to separate their engine compartments from the passenger compartments. It is a very effective product.
