All other things being equal, more port area requires a longer port. It's pretty simple.

Seems odd right? Bigger port area= much bigger port volume for same tuning.

Does seem odd lol anyone have a scientific/mathematical explanation why?

I'm learning slowly but surely lol. My problem is that there isnt really anyone in my area who truly knows what they are talking about so I don't have a car audio mentor to learn from, haha
