Critique Box Design

[Joe50302]

Tried my best to use WinISD and SketchUp correctly, did some math, and came up with this. First time I have used either program It is for a pair of old school MTX ThunderPro TP1540 15's. I was given max dimensions of 40L x 40W x 13H for the install. From what WinISD said, the box should be just under 3ft^3 per speaker. Tuned the port to 35Hz. Any thoughts? Changes I need to make? Suggestions? Improvements?

Thank you for the quick reply & suggestion. I will double check my math and make the needed adjustments.

Made some time to put this thing together. Hope to get it installed next weekend and see how she sounds.
