Speakers made with unusual cabinet material

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.
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.

I have no clue as to where Wilson sources their Phenolic board - it is a generic commodity just like MDF and all the other materials used for speaker cabinet construction. If someone wants you to believe they they cooked it up in their back room with the help form elves and others with magic powers they are full of .....

As stated earlier it is implementation that counts and I do indeed think that Phenolic board is an excellent material for enclosure construction because of its inertness. It requires some expertise to machine it is heavy to move around undoubtedly contributing to the high cost of Wilson's speakers

Google it and you will find multiple suppliers, my reason for supplying the link was to show that Phenolic material indeed are classified in X XX and XXX among others.

Good Listening
