I am building a 2.2 cu. ft. ported box for my IKP. The outer dimensions I came up with are 26x13x15. Now I want to tune it to 28 hz and I came up with a port length of 37". The only thing I am really having trouble with is figuring out how to get the length correct when a turn is needed in a port. The port needs to be 13.5 inches in height and 2 inches wide. Can someone help me out?
