Hi everyone, newbie here with a ?, I want to port my  JL10 w3d4 , on the specification sheet it says to make it 3" x 11.3" , but I only have a 2.5". Im broke right now so I cant go get the 3". My ? is if I use the 2.5" how long would I have to cut it to get the same freq. that the 3" will give me?:errr: I built the box to what was recommended for the ported enclosure. Any help would be great. thanx   SuperBeast
