Speakers made with unusual cabinet material


There were the Celestions with their Aerolam cabinets. The Green Mountain Audio speakers that had a sort of cast marble cabinet. Were/are there other speaker manufacturers that used some kind of odd or exotic materials for the cabinets? Are there speakers with real wood cabinets (rather than veneer?)

Hardwood / MDF / Phenolic / Aluminium / Concrete / Polymer and or a combination of some have all been implemented, all have their advantages and challenges - Its all a matter of how its done.

Good Listening

Mark and Daniel speakers employ "special Compound Marble hand-crafted enclosures"

Wilsons use the "X Material" in theirs
I've seen some DIY speakers made like Magico Minis with layered baltic birch ply.

Sonist uses thick poplar baffle.

I forget the name, but the same guy with the mpingo discs, had thin wall layered laminate speakers.

I have built speakers out of PVC pipe and epoxy urethane.
Thanks, Al, for the links.
And thanks to others, too, for your responses.

Sorry, the name was Shun Mook and the Bella Voce speakers and it's not laminate but birch ply.

There was one I saw made from layered laminate. Same way they make drums.
