Ported box port help
The dims for my box are 17H x 32W x 22D. The port dims are 15.5H x 4W x 28L. Now what im really needing help with is measuring the port walls. From my understanding to build this correctly, for the center line, it'd be, 22 - .75 (for the back wall) - 2 (for half the port width). Which comes to 19.25. Then take 28 (port length) - 19.25 - .75 (wall again) - 2 (half port width) = 6. So the centerline would be 19.25" from front to back, and 6" from right to left, correct? Then to calculate the actual port wall you'd take the 19.25 - 2 (other half of the port width) giving you 17.25. THen take 28 - 17.25 - 2 (other half of port width) = 8.75. So the actual port wall would be 17.25" from front to back, and 8.75" from right to left correct? If im wrong here someone please point me in the right direction, this is bugging the fuck outta me, lol. Thanks for any help.
