SA 12 box

[bokeson]

I want to build a box for my SA 12 using an aeroport but I don't know a whole lot about them. If someone could help me out with building a box for my 12 that would be appreciated

just type in what size box you want, size of ports, how many, desired frequency, and it will tell you how long to make the ports.
