New Box Design

[Wall_Breaker 0]

I need some of you guys to make sure my calculations are good and that this box will work out. This is the first box I have designed to be as critical as needed. I am wanting to try a subs back and port into the cabin approach. This should work out to 6.75 Cu Ft after port displacement and after the 15 " BL's it should have 6.39 Cu Ft at about 32 hz. I am wanting to try to make it bigger and get maybe close to 4 cubes per sub. I have about 7 or 8 more inches to work with to make it a little bigger. But I figured I would make sure I am doing this correct before I go and design another one.
