Front section of a bandpass. Outside dimensions of this half will be 13hx34wx34d. Port is a slot port running along the top, .75inch wood all around, the port width is 7inches. The port will run down as deep as it can without effecting tuning, so 7 inches off the back wall.

All I'm looking for here is

a.net airspace
b.port length
c.tuning.

I've been working on this thing too long and my brain is fried, I know I got the other section correct..

You have 7.029 net cubes but not enough info on port.

Is it 32.5" X 7" ? Or, 7" x some number you didn't include?

And is it common to the 13" wall? If so, it would be 6.75" long.

My fault, sorry as I said brain was fried. Port runs along the top using 3 sides of the enclosure (both sides and the top as common walls) so yes 23.5wx7hx25.5d (depth should be 7inches off the back wall)
