    will someone tell me how big to make my ports?

    internal box volume

    2.314 cubic feet

    this is including sub and bracing displacment, it is NOT including port displacment

    I want to end up with 32 hertz

    and I am going to probably need to run 2 ports because of the way the box is designed.


    FI recommends 12-16 inches of vent per cubic foot of volume.

    I was thinking 2 ports with 4.5 X 6.5 OD, how long would they each need to be to get to 32 hertz?

    It is going to have to be fabricated in a square L7 style. I don't have a MDF wall to make a side from.


    Thank you in advance for any help.

    box is 6x30 inches on top where the port or ports will go, and 21" H outside measurments.

    bottom is 11 X 30

    There is NEVER a stupid question but there ARE always dumb answers.........usually given by a matching individual.

    whats the difference between a slot port and a square port because the difference in length is 5 inches
