aeroport is just a style/brand of port (vent)....wow i feel dumb now lol. i always figure vented was like a slotted port and aero port or was a pcv pipe or somthing
so what you saying is with the amount of space i have if i add 4 more inches to depth to the box and run 2 4 inch flared aero ports instead of a vented box i could run 2 10's then ?both are classifed as ported. You have slot port and aeroports.
Flared aeroports take up less space and is more efficient than an slot port. Add more depth and do two 4 inch flared aeros.
its easier to a proper sq inch port area per cubic feet ratio if its a side port.
