    Help with my Sub box, Please.

    So i'm in the process of designing a box for my 3 Cerwin Vega Vmax 12"s. I have it down to the port now because all the sizes are the max that they can possibly be (33.5,27,15). I'm trying to tune my box currently to around 37hz and i have a port that is 4"x8" and it's 6.25in deep. Do i need the port to be larger? or is it alright at the size it is at now. This will be my first box. I'll try to post a picture.
    Well, it won't let me post pictures because i'm new.

    I get 35.66hz for a tuning freq, but I don't have sub or brace displacement figured in, which a little less volume would raise the tuning some.
