3, top, side, bottom. Using 3 box walls for port walls.

2 is for a straight shot center port which only uses top and bottom box walls for port walls.

you match it with its xmax. The more the xmax the sub has, the more port area it needs. Generally stay in the 12-16 range. I recommended 12-14 since the sub has pretty low xmax and can work fine with less port area.

BTW you entered 1 for common port walls.

with these enclosure calculators, you will still need to figure out the math for the port wall cuts yourself, like the first box tune calculator app you used, it says the port cut is 12x21 long when your depth is only 19.

for the port, you just gotta get down and dirty and figure the length of the wood cuts yourself.

2.5-3 cubic feet is pretty huge for that sub. I'd go with 2 cubic feet at 35hz to have better cone control. If you want, here are some free designs with full proper cut sheets man.
