    **please doublecheck**

    The box EXTERIOR DIMENSIONS:

    H: 17
    W: 38
    D: 19

    Which gives you 5.7 cubes before displacement.

    For your port its going to be:

    15 inches high, 3 inches wide, 16 inches long which will tune your box to 32hz.



    what is everyones opinion on this box for 2 12" '05 type r's? tuned ok for a daily driver? only have one question though.....if the box extior height is 17" and the port is only 15" wont that leave a gap?

    Re: **please doublecheck**

    so i came up with......

    net volume: 3.5^ft3
    tuning frequency: 35Hz
    port width: 3.5"
    port area: 54.25" squared
    port length: 28"
    external dimensions: 38" w x 17" h x 19.75 d

    that look right?

    he also said that.
