i cant not figure out how to build a box right. when ever I do my calcultions it never works out to what the computers are getting.
for instace for a box that is
i multiple these together and then divide by 1728 and get 4.0023 cu ft
but when I enter it in the calc I get 3 cu ft why?
the computer doesnt account for speaker dis either and I know wood dis is not the much. so whats wrong?
