http://www.carstereo.com/help/Articles.cfm?id=29 Here it is. I think that the part of box building included in this site is overlooked too often and that ruins a lot of potentially good stereo systems.

That is a really nice program! Always use a good quality MDF and brace it well. Studio quality speakers always have hard, dense enclosures.

The box is sometimes more important than the driver itself. I've heard really small speakers do amazing things in Transmission Lines. Too bad the boxes tend to be massive.
More reading if anyone is interested.
