Greg,
What do you think of North Creek Music's theory behind cabinet design? In case you aren't familiar they recommend 3/4" MDF with 3/4" Baltic Birch braces spaced at unequal distances from the baffle. Then they recommend a double thickness baffle and rear panel consisting of the Baltic Birch and MDF. I think they also recommend 1" dowels connecting the braces to each other and the front baffle and the rear panel.
Also, as an FYI, a recent article in Speaker Builder Magazine showed the affects of different shapes of enclosures for midrange drivers. The tests concluded that a perfect cube wasn't nearly as bad as everyone states and that the difference between the cube and a golden ratio enclosure were very minimal. Of course the sphere and egg shaped enclosures worked the best. It was determined that enclosure size and amount of stuffing had much more of an impact than the shape did.
