    Icon32 ported box help ASAP

    ok, here's the deal, i am making a ported box, it is going to be a big rectangular port. when i do the math for the volume of the box, do i subtract the volume of the port from the total volume of the box so i tune it properly? understand? thanks.

    Yes.
    Measure the external lenght, width, and height of the port. You'll have to go back and forth since the box volume will change the length of the port and the length of the port will change the box's volume.
    ....don't forget sub displacement too.

    **R = sq.rt. A / Pi (for square/slot port)
