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

If they do it sounds great to me and many Audiophiles who have heard them.Thanks again I'm sure your speakers are great as well.Thanks again.

Here is what I would say about that.  How many CONCERT level instruments are made out of plywood or MDF?

Answer = 0

While a speaker is not an instrument in the sense that you can play it, it shares ALL of the concepts of a device, usually some type of chamber in which sound is projected for the audience to hear and enjoy.  

It would seem to me that Wood would be the obvious choice. 

@bukirob What sort of logic is that? 

buki is exactly on point here:

Since I listen to mainly jazz vocalists my speakers are made mainly of deceased jazz vocalists. You would not believe how long I waited for this pair. Touch and go for a while, I was worried the singer might recover.
