New project. Woods cut and assembly has started. It's 6.226ft^3 cab. 21x13.5x48 od.

Out of curiosity, how did you come up with the dimensions for the enclosure? I'm anxious to hear how you like it. I'm a fan of single driver units; I think because of their relative simplicity.

The dims and sims are posted in another thread. GM did them. I'd copy and paste here but, I cant get it to work.

Thats them. Thanks for putting them here. The main part of the cabs are done. Need to figure out the bracing inside. Still waiting on the ports from PE.

You're welcome, what are they made of?

There birch ply. I think I'm going to put x braces just below the driver and then about 14" up from the bottom. I'm going to make the bottom bolt on with a gasket to seal. That way if I need access to stuff, it will be easy.

How thick/number of plys? Regardless, unless you use 2/3-3/4 cab length vertical strips [~3/4" x 21/2"] turned on edge with interlocking tie bars to create the 'X', then bracing locations follow the same as for driver, vents, i.e. ~1/3rd, 5ths.

Ideally, the top plate [bottom also if spaced up] needs to be rigid/massive, so adding a massive top plate [removable for heavy cabs] is a good plan. For WAF, heavy potted plants and/or slate, marble work well, which I make small recesses to Velcro [industrial grade] them on.

Are you saying to glue two 3 3/4" strips together. Then place it from top plate to bottom? I'm guessing it would go in the center of box. Or I can put two 3/4 x 2 1/2 x braces at Zd and Zp. Or do both?
