Aeroports?

[BumpinAlong 0]

So I've been reading a ton about aeroports and I've heard they reduce port noise and take up less space therefor reducing box size. I want to do two SA10's in 3 cubic feet tuned to 33 hz. I've been trying to use all sorts of different calculators and such trying to figure out port sizes and what not but its not coming together for me. Basically I want to know how you figure out port length and diameter as well as port displacement in the box. Also where is a good place to get these ports from. I'm going for a really nice sounding setup that can get loud if I wanna show off a tad . Any info I didn't include just ask and I'll do my best to fill in the gaps.

Thanks
