it doesn't matter how the port is inside the box. its the length of the port that determines the tuning frequencies.

if your tuning requiers you to have a long port then you can do it like a maze or just run the port wall along side the box wall. just make sure the port is same width all the way through.

i am not sure exactly if this is what you want to know but i gave it a try.

port length remains constant but the reason it ends up like a maze is due 2 how u would like the dimentions of the box 2 be especially when u ask 4 it 2 be a more squarish design but if u input it with 1 side being kinda long the port sometimes showing up very simple with only 2 bends in it

play around with different height/width measurements & u will see it 4 urself ....

longer ports that need bends or turns need to account for the shift in air velocity as well.

some boxes you see with a lot of turns in the port walls aren't straight ported enclosures, too. They're tuned folded horns or transmission line enclosures.
