    Re: Anything wrong with this box

    I get just with the basic numbers more like 20 Hz tuning based on a 3" port.

    What did the designer tell you about the box?

    hmm... the ports don't fit? The numbers are right, just doesn't look like the tuning it even close. What specifically are you looking to do?

    THat design equal ~

    Net Volume: 3.15 cu/ft
    Tuning Freq: 25.94 Hz

    That's closer, but I would go with a little more port area.
