unless you have built a lot of slot ported boxes than I would stick with aero ports

how easy are they to tune?

Maybe some one else will chime in I don't have much experience with aero ports I just knew where a good calculator was located. I used two 4 inch aero ports in a 6ft^3 box for a 15" home theater setup and there is NO port noise and hits crazy low. They are two totally different situations though. I would say try 2 4" ports and see where that gets you.

2 4" ports isn't enough for 1 18" sub. I was running a 15" hdc3 and had 3-4" aero ports

2 6" aeros would be 57"^2 of port which i think youd be fine, three would be optimal maybe a little overkill. i would think a lot more expensive than a slot.

a slot port would require more port area, which also means more volume displacement....so if you're trying to save some space, go with the aero's, they require a lot less port area than a slot....2 6" aeros would work pretty well in 6cubes....giving you 56.52 sq" of port area, which is about 9.4 sq" of port area per cubic foot.....3 6" aeros would work, but it would be a little high on port area

only reason im using aero ports is they seem easier to tune i think?

would each port be 16.2 long or is that total length according to PSP aero?
