    Pink Stucco speakers. Sorry, it just jumped into my mind.

    Aren't there some designs out there that call for things like asphalt roofing tiles to line the insides too?

    Start with 1/2" baltic birch or OSB. You'd have to build the whole cabinet complete with internal bracing before the next steps. Slather on the mortar, attach and screw down the cement board, tape the joints, etc. You can finish this off with more mortar and tile. Any type of tile- slate, polished granite, marble, etc. It could look pretty awesome I think, especially if you did good work on the tile. I think our tile was 3/8" thick porcelain tile, very strong and heavy.. very heavy. I think 10 tiles (10 square feet) weighs 26 lbs. So anyway, with 1/2" OSB or plywood starting out, you are talking a minimum of 1.25" thick, but probably more like 1.5" thick.

    It would be very heavy, very stiff, and could look fairly slick. It wouldn't be that expensive either. You could do any number of interesting things for the front panel, including solid granite.
    I bet they'd make a great match as bathroom speakers. :D

    One can go to great lenghts to dampen cabinet resonances. Just look at the early B&W matrix cabinet designs. At some point, however, the law of diminishing returns prevails.

    Actually, replace the "slather with mortar" step with application of roofing repair film to form a classic CLD sandwich. Then cross-brace to the tile / cement board. Works very well for me!

    HAve fun,

    PS remember, no one can see the tile inside, so pretty cuts are optional

    Bob Brines uses backer board in his cabs.

    I know Rudy Jakubin has used concrete backer board for internal wall treatment. The extra mass really deadens the walls.

    There are already a lot of "constraint layer" constructed enclosures around TT. Look for BillSchu's MOAB. The bass section began with MDF, then was completely lined with mortar then ceramic tile. Very nice enclosure design if I do say so myself.

    I forgot to mention a part of my "idea". You would want to use the polymer-infused mortar, sometimes called "Flexbond" which is much more crack resistant.

    Such as this:
    http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051

    I think the 1/4" cement board comes in 3x5 sheets for $8. A huge bucket of cement board screws is $20. Thinset/mortar is $20-30 for a huge bag. Marble, granite, and other interesting tiles in 12x12 size are $3-8 each. Grout is pretty cheap.

    Cutting tile can be interesting- made much easier with a good tilesaw and a good blade. I'm not positive what the process is for cutting solid stone tile since I didn't do that.

    Cement board in and of itself is an interesting product. It's got fibers in it, possibly fiberglass. It's stiff but not invincible, it's somewhat brittle.

    Interesting idea. I like it...

    ... but I might be worried that the mortar would develop cracks over time from the constant vibrations.

    I don't have enough experience with tile, mortar, grout etc... to make an informed decision on how it would hold up in the long term. Does anybody else have experience in this regard?

    One more question... would this be considered a variation of the "constrained layer damping" concept?

    Possibly new cabinet idea

    So a couple years ago we tore out some nasty carpet and crummy linoleum in the kitchen/dining room and replaced it with tile. We did the research and did 420 square feet of tile ourselves.

    Anyway, the process of preparing the floor for tile was interesting to me. On top of the 3/4" OSB subfloor, I put down mortar and then covered it with 1/4" cement board and screwed it down with a (large amount) of special screws. On top of this goes more mortar and then tile, and finally grout. The idea is that the cement board layer is very stiff (and heavy, I might add) and reducing flexing in the subfloor, especially around joints.

    So anyway, had this idea for walls and back of a speaker cabinet.

    Start with 1/2" baltic birch or OSB. You'd have to build the whole cabinet complete with internal bracing before the next steps. Slather on the mortar, attach and screw down the cement board, tape the joints, etc. You can finish this off with more mortar and tile.
