    First off, very nice choice on the Cerwins. I also have 2 of them, although they are the Vega 10's. Going from sealed to ported is going to sound awesome. However, I need to know the size of the subs before I can help you.

    Which version ? Start with a new project, select your sub and the type of box you're thinking of using. The vega 124s are in there... think the others are as well.
    Then you'll want to input volumes, have it figure port length. It's not particularly useful except for helping to show the flat response curve you're looking for with varying conditions (I dare say it might be most useful at telling you how far messed up little errors will be... and putting your mind at rest). I'm not a very power user of the program, but it helps hone in on what size box and port you want to use. BTW, the dimensions it gives for boxes aren't very good... while they may end up with the right volume, they just seem out of whack as far as proportions.
