Can someone check this box out for me please?

Okay so I'm going to be building my second box here shortly for a pair of IA LI 12s and I was wondering if someone who knows better what they are doing could take a quick look so I can be sure I'm not way off. It should be about 5 cubes without the port tuned to 32 hz. with 74 sq. in. of port area and a port length of 29.85 inches. Please excuse the crappy Powerpoint art work. I havent actually factored in the displacement of the subs or any bracing that I might use because even with it it will still be well within recommended specs. I might make it a little bigger but wanted to make sure I was on the right track before I go messing with anything. Thanks in advance.

You think? Recommended from IA was 20-35 sq in. per sub if IIRC. Maybe if I decide to make the box any bigger I'll make it taller to increase the port area.

 
It's pretty hard to totally mess up a rectangular enclosure. Looks good to me. The port should be adequate - you shouldn't get much port noise, although I suppose adding some more if you have the room wouldn't hurt..

 
I'll have to check my dimensions in my truck because that will give me a whole lot more displacement for the port which will mean a bigger box externally obviously. The port will need to be like .7 cu ft larger to reach desired tuning that way. Thanks for the input though I'll have to do some measuring.
