How is that for an XXX18 7.5cuft NET @ 35Hz... can some one go over the calculations to make sure everything is good to go since this is my 1st box ever made and i really really **** at math, i can barely use a calculator aside from the positive,negative and division.

The port is suffocating. I just ran the calc, and it needs like 172 sq in of port area, Im not even gonna run the length....it will be scury

And 18.5" on the baffle may be a little too tight. I would go with 19 at minimum from the looks of mine (old claw basket)....and a double baffle (1.5")

How about the following....

-Box Dimensions

18.5Hx40Wx24.74D

-Port

17.5Hx5Wx21L

This gives me a tunning of 34.72Hz with 7.5cuft NET and 8.8 gross, what do you guys get?
