I have 2 Skar vvx-12's on there way and I just bought a sheet of 3/4 mdf so now I need some help with box design. There website suggest 1.75 cuft per sub after displacement tuned to 36hz, 36hz seems a little high to me... I want a good combo of spl and sq. I will be using 4" aero for this project, I have 2 aero ports but im not sure I should use both or just 1.. I can go 48" wide max and 17" tall max and however deep I need to go. Any help would be much appreciated.
