    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.

    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.
