port question

Here is a quick picture to describe my question.
When using a slot port does it matter where (on the port) the port exits the box? The measurements used were just to show that both ports are the same size. Are there calculations that can be done to port it like "B"?
If the port is right at the bottom of a box and there is a board that extends out from the bottom of the box, does that effect the port? Basically the bottom piece of the sub box extends out 4" past the face of the box.
Thanks for any help.
Later,
Brad

Corners always decrease vent efficiency and increase turbulance. If you have the choice, go with A. If you don't, try to make your corners as smooth as possible - think of how water pipe has nice rounded elbows rather than hard 90degree corners.
A vent right against a floor or wall will 'shadow' it, effectively increasing the vent length and lowering the box tuning, by about half the width of the vent - the same as when you use an interior wall of the box as one side of the vent.

Thanks Paul,
It sure adds a lot of variables when building ported boxes. Sealed is so much easier.
Between trying to save trunk space, port the box properly and in the right location, and making it look good, I am tempted to go back to sealed and be done with it !!

Your car adds the added complexity that I would try to avoid any radiating surface or outlet forward of the back of the rear wheel wells unless you are going to go to then lengths to totally isolate the trunk from the cabin and radiate only directly into it.
