The talk about solid wood is interesting but also misses a mark totally.

Being a woodworker, I get to work with the stuff on a constant basis and as a result have gleamed quite a bit from that. Beyond staying at the Holiday Inn. Building speakers out of solid wood would be a step towards impossible. I have yet to find two boards of wood that are the same. It's a living thing and as such each part of the tree has grown up differently. I have had boards that came from the same tree, bookmatched so I know they are consecutive cuts, and yet when you work with them, they have different stresses and move in slightly different ways.

MDF is consistant. It has the same density throughout. It doesn't expand, contract, or move in un-uniform manner depending on direction of the grain as it has none.

You talk about resonance of the wood. Think about a Stradivarius, no two sound identical. It's wood and so it will give a different sound even if they are made identical.

just my two cents worth, wanted or not
