lets say you were using two 4 inch ports that totaled 40 inches long each for that port tune you would simply take the inner diameter and divide it by two and then your port length would be half its original depth
so youd get 4 two inch ports 20 inches deep compared to two 4 inch ports 40 inches deep
the port should be 37.8 long with a true 3 cuft. has the woofer displacement been accounted for?

i want to build a ported box for my solo baric l7 12s someone please tell me how to do everything for this application. i've been reading for hours and searched to find a building program but i dont know the specs on my subs like the xmax i dont even know what that is. thanks a lot.
Id assume winisd does not factor in woofer displacement (room the sub takes up in a box) because they wouldnt be able to do it accurately you add this to your target net volume internal desired for your box. In this case the box volume is 3 cf net so youd add i dunno a random number here .15 sub displacement plus 3.00 cf net desired the internal cubic feet would need to be 3.15 cf. you must also factor in port displacement. (room the port takes up in the box) Im also going to give you a link here that explains how to account for the port displacement and adjusting the port length properly.
i know i understand how to add port volume and subwoofer displacement -- i just figured winisd pro would do the sub displacement automaticly.... since you add the size and displacement of the woofer when you enter one.. thanks though... i just want to know if a 38 inch long port is to long?? i dont want it to have slow response and sound muddy
