This is going to sound very elementary to most of you but I do not know the answer.
I have 4 enclosures shown here. A, B, C and are the same exterior dimensions minus the port.
A: Sealed box 200x200mm
B: Ported box 200x200mm with 25x150mm port
C: Ported box 200x200m with 25x150mm port - question: since the port is folded inside of the enclosure, does this mean that the enclosure size is now considered 200x200 minus the port size? Or does folding the port into the box maintain the same "enclosure" size. I do not understand how this works. Please explain to me.
D: So here we have a more complex design. Forget mathematical dimensions. Which area of this is considered the "enclosure" area and which area of a box like this is considered the "port" area?
Thank you for the responses. This has been confusing me for some time.

The enclosure volume stops at the entrance to the port for both B and C.
I do not have the answer for D. The smart guys will have to help.

Net volume. The gross volume of any part of the vent inside the box needs to be subtracted.
The forth diagram is a TL with quite different behaviour. I’m assumming these are slices thru the box, and the openings are full width.
Vents are usually hidden inside the box, but not always the case.

A vent has its own air mass 'plug'/'slug' that vibrates to make its output and actually extends beyond its length at both ends, hence its various end corrections, but not normally accounted for, so its entire exterior bulk must be subtracted from the net Vb and obviously if any of it sticks outside, then that portion isn't part of the subtracted amount.
