PSP-inc calculator question

I was playing around with a box that is 3cu ft. I want to use 2 4" ports (or 6" Ports) So I was woundering, the length that it gives, is that each port needs to be that length or thats how much total port length it needs?

What would move more air overall, Kerf, Slot, or Aero Ports? The sub I'm playing with in mind is a 15" Adire Brahma MKI.

its not the ports that move the air, its the sub

the smaller the port, the more air would travel through it, creating port noise.

id go with a single 6, or a pair of 4 inch ports.

im not familiar with PSP-inc though, so ill let someone else handle tha tpart...

Sorry, I miss worded it. I would like a very effient port without port noise.

Also I would Like both the subs and port facing back, but my box's depth will be 15" and the port needs to be a little over 20" (32hz) plus lenght to the back of the box and I dislike external ports, What can I do?

You might need a port elbow for daily tuning...that's what I'm gona have to do when I get to building my 3 cubic foot box for my 15" Nightshade.
