    Ported box -

    Recommended Volume (Cubic feet) - 1.0

    F3(Hz) - 35

    Number of Ports - 1

    Port diameter(Inches) - 3

    Re: ported box rockfordfosgate

    Basically the only thing you need to do is come up with the width and legth that will equal the area of the port.. for instance

    a 3 inch tube port has an area of

    3 x 3.14 = 9.42

    so the slot port could be

    1 inch by 9.42 inch

    the port length stays the same.
