I don't know what you don't understand about displacement and tuning frequency.no, it means the calc is garbage lmao. Even according to winisd the port area recommended was way closer to what i experimented with rather than that stupid calc that does not factor in TS specs nor power.
Look at the Excursion graph when you plot your driver take that number for the maximum Excursion and put it in the calculator like I said the calculator is older and takes an account for quite a bit more SD then the typical drivers so it's off a little bit.
Even if you read when win ISD you'll see that only displacement and tuning frequency give you vent velocity
