"You also have to take into account "port noise" from the air pumping in and out. Speakers with more volume displacement (Cone area x Xmax) require wider ports... and the wider the port the LONGER it must be. So you want the minimium port diamter so decrease the port length."

So if the Xmax is a larger number i need to make the ports wider? Cant i jus use 2" ports the whole time or i have to make it larger
