When i plug in the numbers on this website for a 4 inch diamater, it says i need 14ish inches of port to get 40hrz, when i enter 2 inch diamater, its only like 2.75, is there a benefit of doing it either way?

The larger you make the port area the longer the port needs to be to have an equivalent tuning. How much port area you need depends on the setup.
