So after talking to my box building friend (went to school and everything for it) he says that since these X5 boxes in general are so small and don't have lots of large flat areas, that we're fine using 1/2" instead of 3/4" in order to get the most internal airspace. I personally am going to see if we can get the required .35-.5 cu/ft of airspace so I can port my 8" sub Technical Specifications - RE AUDIO and really get more sound from it. To answer my own question, all airspace measurements below are internally and using 1/2" MDF to calculate airspace. I've listed them from in order from easiest to hardest to make.

Essam's comes out to .035 cu/ft. Essam estimated .05, we came up w/ .53...but that is externally...we need to worry about internally.

Dib's comes out to .36 or .32 based on whichever design you chose to use. (per his measurements, so we didn't recalculate because they sounded pretty accurate)

Zerochief - as you know, you're box optimized spacing the most since you've got soo many cuts so it goes into every nook and cranny. After LOTS of clicks on the mouse and subbox building software, it came out to .41 cu/ft.

Unfortunately I still won't be able to port it because the port would just have to be too long (2" round x 9" long), it'd be too close the the internal walls, and it'd give lost of port noise Sealed is the still the way to go still. When we first started this project we made the simple .3 box that would go into the left hand compartment. He's currently making me a .413 box just to prove a point that while Zero's box is the best and most utilized, my builder claims that I probably won't notice the difference between the two since this box is so small as is. Ported would make the biggest difference, but it just can't happen while trying to keep it stealthy behind the panel.

Either way, kudos to those who took the big step and created these...I wish I would have done more research before hand, but at least i'm still only into this project for like $160 completed.
