    How do I find the port length and diameter using pvc?

    Trying to find out if I should use 2 aero ports of 3" in diameter or 1 port of 4". They both would be around the same length for 32htz. Is there going to be a difference? Thanks

    Too many variables here.

    What sub?
    T/S parameters?
    Net volume of box?
    Tuning frequency?

    I have a hard time believing they"ll be "around the same length" and still have the same tuning frequency.
