Which material sounds better for speakers construction? Wood, Ply or MDF?

“Give it up dude, you obviously have not the slightest understanding of speaker physics. I'll await your reply with a claim of BS credentials”

I know this was targeted at someone else but if you don’t have anything productive to add to the conversation you should just skip this thread and move on. If you feel real strongly about your speaker design knowledge/skills, write a paper and send us the link. Personal insults are not welcomed here.

I see that Magico has added a new M series speaker with carbon fiber planels. Carbon fiber is very light, read: low mass. 

They have tried many other materials for their cabinets  and now choose this produce. 

Perhaps there is something to the idea that low mass high resonance is a good idea????

Magic M3 weighs a healthy 320 lbs. each! Looks like the CF “panels” are more like an esthetic touch than structural. And the (internal ) aluminum bracing is quite extensive and incredibly impressive. 

carbon fiber makes sense to me... it is a very dense material that is dead and if bonded over another would offer a very nice damping material.  

Sorry to butt in but carbon fiber actually has a low density. High strength, light weight, low density. But, interestingly enough, high electrical conductivity.
