Re: (aeroport box) Need some quick help
You will need to compensate for driver and aeroport displacement so box needs to be closer to 2 cubes
hence, port in or out affects the size of the box.
adding another port changes the tuning of the box so if you want to run two ports so the box can look better, run two smaller ports with the same internal volume as the single port.
The direction of the port will make a difference but that changes from vehicle to vehicle there is no one way, its one of those things that you just have to build it and see which way sounds better.
