I wanted to do about 6 cubic ft about 35hz so i went onto a website for building a box like the calculations this is what I got 31w,20h,21d,3/4 wood = right about 6 cubic ft, now it says port size but with the 3/4 wood on each side how long would the port have to be and how wide would you say for 35hz?
