I see what your saying but, I always thought that you figure out port lenth by port end correction?(i.e. the blue line in the middle of the port)if your port is 6.5 wide i would try to keep it the same distance from the back wall. if that means the inside of the port is 11 inches then just put in another piece in an L shape to the right that is 5.5inches
I know that, I meant when your drawing box plans and or building the box. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifyou determine port lengt but how big ur box is and what you want it tuned to
