Im not sure if these numbers are correct. I am building a box for 2 2XL15" pbx Subs I want the box to be w-43", h-19",D-20". which gives me 9.4 cu ft correct? Im going to use 2 slot ports and i want it tuned to 35 hz. I tried a couple different port length calculators and i came up with a H- 19", W-2", and depth 12.7". Is that correct?
