    Quick Box designing question.

    When using Winisd, I first put in the volume that the sub will see.

    Then I find the port length at the desired frequency.

    The I add port and sub displacement to the first volume I entered, and build the box that size.

    Re: Quick Box designing question.

    yeah u get port length first. then u need to use 2 dimensions and add the displacements thus giving ur desired tuning and desired volume while getting the correct third dimension.
