View Full Version : Aeroport ? for an Idmax 12 enclosure

02-21-2013, 05:10 PM
My enclosure will be 2.5 gross before sub and port displacement. I was going to use a 4" port but not sure how long to make it for a 28hz tune.Can someone help me with this please. I tried using psp calculator but I'm totally confused about subtracting the port displacement. Ido know the sub is .14

Just use a full length 4" diameter port.
