Hey, I do have a question though if anyone cares to opine. Notice I've only closed up half the back. I could not decide whether to close up about another 3" from the top leaving about a 3" gap for air flow. So, before you tell me "it depends on your taste etc..." my question is, if you were doing an open back cab of this size, what would you have done on the back or rather how much would you have left open? Wouldn't take me long to close up a little more of it and was just curious what you guys thought.
Thanks for looking and any response you might want to give on my question

I built a closed back speaker cabinet using AX84.com plans a while ago, and according to its plans and their forum, is you leave 1/3 of the back open it's as good as leaving the entire back open. In other words, as long as 1/3 or more of the back is open, the sound shouldn't be affected.
As for other build advice...
1) It looks great.
2) I think from a capentry standpoint, the boards should have been arranged across the width of the cabinet instead of the depth (if that makes sense). Imagine sitting on the cabinet and you can imagine your glue joints breaking. i don't think it will happen with the bracing inside the cabinet and the front baffle, but from a carpentry "theory" standpoint, I think the grain of the wood should run from corner to corner, not front to back. So, for next time, that's what I'd do. But, like I said, it looks great.
