[QUOTE="coolest user, post: 3619448, member: 581593"] The box I have drawn up for the 3 12's with 1 port is... 5.25 cubic feet net internal volume with a port 3.25" x 20" x 34.5" long. subwoofertools says use a port 2.5" x 20" x 27" long.

If not, I'll try something different. I don't have a clue about the effects of changing port sizes... . [/QUOTE]
