I'm just trying to make sure that I'm measuring out the port length right, there's gotta be someone that has built a ported box on...

add the end correction of the port (half the width) to the length.

Um, i thought you subtracted it to make up for going aroung the corner...

if you do not have dimension yet, you subtract from the length you calculate. if you have set dimensions like the one above, you add because the wall will increase effective port length.

I'm building the box tomorrow, I'd really appreciate feedback.

Ok, this is how I determined the correct length of the port (I believe).

If I did it EXACTLY like this, I have the correct dimensions correct?
