It's called SketchUp. Made by a company called @Last, until Google bought them out.

blackbonnie **** that looks good.....will it sound good that design, and if you increase the port are, will it dramatically change the tuning......

The port is ~20 inches to give you 33.5 Hz... also, you shouldn't need much more port area... just make sure to give the port @ least 6" clearance for major obstructions and you'll be ok.

as far as adding to the port area, it will defiantly change the tuning and net volume the subs see.

I personally use the pro edition cause I get it for ~2 bucks from IUPUI.
