Trying to figure out something.
I understand aero ports and a lot of people day like 7-9" per foot.
I understand slot ports and average for those is 14-16 per foot.
What I don't get is the square ports that are stuck into the side of the box and are half or more than half external.
I get how to make it and tune it and everything, but what port area do I want? Are they as efficient as Aero's or are they somewhere in between?
