    Re: port area

    If you increase just area your tuning frequency will go up in Hz...quite quickly I might add. This will eventually kill the output of the lowest frequencies.... most would describe a sub with very high tuning as "boomy" or "muddy".

    Ask him to design you a box specifically for your application.

    Re: port area

    well then calculate the size of that box in ft3 and just take away from one length and add to another until you get around the same size.
