The greatest thing about surfing the net is finding all the neat programs you can download. I have found approximately a dozen and speaker design CAD programs which are of great use to the amateur speaker builder. Unfortunately, some 'free' and shareware I have found are, which makes them nearly useless. Others are rather complicated, and require that you know a bit about enclosure design and provide very detailed information about the sub, much of which is not included with your average purchase.
So I looked through my CAD software and came up with the programs I use most, and which I believe nearly anyone can understand. For some in-depth analysis about enclosures and design, go check out the website and their excellent. If you know of any great free CAD programs I have not listed, please contact me!

Blaubox is designed so that it will figure an 'computer - generated optimum' enclosure smaller than an actual 'optimum' enclosure - this to save room for the auto environment. There is no selectable Qtc for sealed speakers (default seems to be Qtc = 1.0), and ported enclosures are often figured at half the volume of their actual 'optimum' size. Bandpass enclosures are also figured rather small, which means your bandpass design might sound boomy. If you know the actual optimum size (flattest response down to cutoff), you can input this into Blaubox.
That said, you can choose between sealed, ported, single reflex bandpass, and dual reflex bandpass, or isobaric variations of these designs. A speaker database allows you to store info on all your drivers, available for instant review. It also plots the low frequency driver response, and you can display two separate enclosure/sub designs at once so you can see how different designs compare with each other (VERY useful). Although programmed with automotive applications in mind, this program works well for building home speakers too, as long as you remember the above warnings!
