Birch, oak and walnut are acoustically "stupid" woods and you want to have nothing to do with them. If you must use something other than MDF use cherry. And, yes, cherry can be very different. I think, Michael Green used cherry in his reference free resonance Chameleon speakers. If I remember right he imported it from a particular mill in Canada. And the way the cabinets of his speakers were constructed required serious skill and great hearing. Are you up to this?
Acoustic guitars's top is made of spruce, right, but "the body" can be made of different woods. Of what I heard a guitar made of some sort of rosewood sounded best.
