    Re: tunning question

    6.34ft^3 gross
    -.96ft^3 for port
    -.4ft^3 for subs
    -----------------------
    ~5ft^3 tuned to ~39hz


    Might be a little different if there's bracing taking up some space...I'm also just guessing on the sub displacement, but it should be fairly close. Also, this is assuming the 19" port length is from the back of the port to the face of the double baffle, so only 17.5" of it is taking up space in the box.

    It'll raise the tuning a little. Taking away air space raises tuning given that the port stays the same.
