Sorry to repost this again guys but it won't let me edit the original post anymore with the new link.
This is an EXCEL based box calculator which will automatically figure your inside AND outside box dimensions for a given enclosure size, port configuration, and subwoofer displacement. Doing all this at one time eleminates the need to constantly refigure your box every time you change something such as port size, tuning frequency, etc. And when you change something it refigures it on the fly. So far everyone who's tried it seems to like it. I'm putting it out here for the real world tests. If you don't have excel download OpenOffice it has an excel compatible spreadsheet program and it's FREE. Let me know what you guys think of this little tool. Enclosure drawings for your designs are soon to come with cutout dimensions and the works!
