I got many different box designs for my subs (some have big ports, some have small ports, big box design, small box design etc... you get the point) and I really don't want to build one and find out it sucks, so I was thinking a lot of people build boxes. The begining thread said use the WINISD Pro program but I was wondering what programs do you guys use. Or at least what is the best program to mess around to see what will be the best box to build.
