I had the same problem. I downloaded a free software called WinISD pro. All you have to do is fill in all the parameters about your sub and u set the box volume and tuning frequency and it gives u the port size. If u have any questions PM me and ill be glad to answer any.

hmmm if i take the total area of the port opening for a slot and figure out the diameter as if my slot was a circle using the formula for circle area will that work?
