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?)

mmm implementation of Wilson also their materials are the primary cause of their horrible sound.
Wilson "horrible sound" = problem(s) upstream !!! Start searching for what is being exposed in system or room !!! IMO!!!....YMMV !!!!
Wilson Benesch use carbon fibre and the veneers done by the guys who make dashboards for Bentleys! Swish.

Sebrof,
X material and M material is just a fancy word for Phenolic board.

So you are saying that Wilson sources their material from San Diego Plastics (your link)?
I have a pair of Celestion SL700s with aerolam cabinets; they are really good, rather light, and have their own stands. It is a shame that Celestion did not continue the line.
