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

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.  

@kalali,

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.

That poster is spreading misinformation. He clearly confuses amplitude with frequency - rather basic principles in audio. Even though I pointed this out to him, he continued to spout nonsense as though it is fact. I make no apologies for the ignorance of others. There's far too much of that going on in our culture these days. Peace.

@geoffkait     Well actually you are correct, I really should have thought through my words better... it is low density, because it is lightweight, but I guess we could compare carbon steel or you could call coal a carbon as well as diamond a carbon, but no,  I meant carbon fiber, more like an epoxy.  I thought you were part of the forum,  its called chiming in, not butting in.  So, I stand corrected, but still contend that this could be a very nice material combined with another.
