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

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

@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.

After reading all these technical comments just realized how deep and elaborate speaker cabinet construction can be.
Its a science unto itself.
I remember they have thick books on enclosure and cabinet building.

Might need to take a couple year college course to understand the concept down to the finer details.

The brits seem to understand the science of speakers very well.

Nice observation and thanks for reading them. Wilson Beseech has done more R & D into speaker and driver construction then any company I know of, perhaps all of them put together. On their website they have so much information.
