Default So confused on this aero port length tuning, need guidance bad.

Ok listen everybody, this is my first time using aeros, I'm buying two 8" kits from Derrick on here and I need to no wat to cut the tube to. My box is 9.83 cubic ft net after displacements for three zv3 15s, Subs up port back. I want to tune to 34.8hz. Psp calculator tells me it needs to be 17.9 with flares , but here's wat I confused about it, is that 17.9"s from flare to flare meaning if I took a measuring tape and measured from flare to flare it would say 17.9 or is that from the bottom of the outer flare to the bottom of the inner flare. Pictures would be nice if anybody has some showing me wat psp is measuring from.

Ok so if I need 17.9 total, let's say the front and back flares are 5"s tall each so that's ten inches total so the tube will be 7.9 inches rite
