Does WinISD calculate port/sub displacements?

After designing a few boxes with WinISD i have became sketchy about displacements.

My question is

Does WinISD calculate out the port displacement and sub displacement when it comes to the volume and tuning?

idk im too lazy to try this but try selecting two different subs with the same size box and see if it tells you the same or a different port length

No it does neither. Winisd is not an enclosure designer; it calculates port lengths with a given area and net volume.

It only crunches the numbers for port length. You have to know what you're doing to translate the output of any box program into a workable box plan. It's very basic math that, sadly, many people prove to be basically stupid on.
