    12w7 Box dimensions

    Building a new box today for my 12w7. Sealed wasn't enough so I'm gonna go ported this time. Can anyone give me dimensions on a box Similar to the one recommended on JL's site except with a few more cubes?? Looking to get around 3 cubes with a slotted port. Dont know how to calculate slot ports.. Anyone give me some dimensions??

    Legth x Width x Height / 1728 = cu ft

    i would do it for you, but this will give you flexability to work with the dimensions you have.... i can help ya further if ya need it though...

    Well, the main problem I have is the slot port. The calculator I used only had calculations for round ports. If I go with like 4 cubes, how long does the port need to be?

    What do you want to tune it to?

    Well, JL recommends tuning at 32hz but i'd like a bit more BOOOOM so maybe like 26hz? Should peak around 32 correct? How big a box could I go before SQ starts to go down? I'd like between 3-4 cubes, but I'm not sure how big and how long of a port...
