When using winisd pro to model an image dynamics IDQ 12 D2v3, box size just under 2 cubic feet, 4"x3" rectangular port (inside dimensions) it seemed like the port length of 20" was a little long. So I looked at image dynamics website, downloaded the specs, and then modeled it in a 1.5 cubic feet box with a 3" round port tuned to 30 hz. The port length was much longer with winisd than it was in image dynamics spec. Which one would you go by?
