    shorten the second piece of the port from 14.5" to 4.5" and you get 2.3 cu ft @ 39.3 Hz.

    hope that helps!

    tuning will vary a bit between programs anyways, but if you NEED it tuned a little higher (I don't know why you'd want to tune that high to begin with), you can just take an inch or so off the port length.
