im getting a 15 BTL and it will be powered by a zx2500. i got this off the RE calculator. i did two different port widths. which do u think i should go with? feel free to make suggestions to changes. this will be my first build.

33x17x21, 67.5sin port area, (volume - 3.8cuft), @ 32.68hz (this is with 4.5in wide port)

33x17x21, 60sin port area, (volume- 4.3cuft) @32.5hz (this is with 4in wide port)

I don't think you need the extra port area. 7.5" of port area but it won't hurt anything. Without double checking those numbers they look reasonable to me. Go for it!

I would say go with the 4.5 cubic foot box one. You won't be disapointed good luck with you build!
