RAM_Designs Posted May 3, 2011 Report Posted May 3, 2011 4". If you do 15.25" you're looking at over 40" of effective port length. Alright thank you Can you tell me how you came up with the 4"? I just laid out the box and found the needed port length by going down the middle of the port and accounting for the 45° end correction.
