When I built the box for Roscoe a few weeks back I got a 4x8 sheet of 23/32 plywood for $36, but my ears aren't good enough to hear the difference between that and 3/4" birch.

I like the birch for more than just sound. it takes a kerf bend quite nicely and doesn’t chip out as easy as some others when I’m going around the edges with the router. Although a good sharp bit is probably most of that. It also seems to hold up to time quite well even unfinished.When I built the box for Roscoe a few weeks back I got a 4x8 sheet of 23/32 plywood for $36, but my ears aren't good enough to hear the difference between that and 3/4" birch.
I'll take a look at what the other options are, and I'm sure none of them will be cheaper than MDF.I like the birch for more than just sound. it takes a kerf bend quite nicely and doesn’t chip out as easy as some others when I’m going around the edges with the router.

Yep it’s been proven a proper wood glue joint is stronger than the wood itselfYes MDF with lots of glue works well! To prove a point I once built a box then once the glue was dry I removed the screws as they only needed to hold it while the glue was drying. Then silicone sealed the inside and 25 years later it’s leak free.
Ya, it's pretty dense, so less reasonanse. No voids like most plywood. I always stuff batting in there as well to cut down any boom not coming from the subs. And supposedly it tricks the speakers into thinking the box is bigger than it is. That was the thinking 20+yrs ago anyway.I could be wrong but I always read that MDF was preferred because of the acoustic properties
