Re: Yet another Port Q
i say this sooo often. port calculators do not account for port displacement. if you made the box knowing the port displacement ahead of time and included it in your design, your fine. if not you will need to do the math twice. once to get the port length and find it's volume. and again using the box volume with the port volume subtracted from it. make your port to the second calculation's length.
