I know (or at least I think I do) that these look for 2 cubic feet each, so 4 total. And they should be tuned to 34hz. After that, I have no idea where to go as far as designing the box, dimensions, specifics, tweaks. I am visiting family right now where I have all the tools available so I am looking to build this in the next few days. Ive tried googling some box calculators but couldnt find anything like I want. A while back I remember there being a program that would do everything for you and tell you what to cut to what size. I'm basically looking for that.

Long story short, I don't know what I'm doing, and I want to make a nice custom enclosure for 2 12's, can anyone hook me up with some diagrams or a program that does all the dirty work for me?
