I have good luck with a .4 cu box

ALthough it is a little off topic, here is my input on small sealed speaker box designs.
I have had good luck with very small sealed enclosures for my 10" pair of sub woofers that I bought from madisound (http://www.madisound.com). I was very surprised to find that the design called for only 0.4 cu ft boxes for each speaker. According to the spec's, there is a powerful in car freq. response down to 15 Hz where the roll-off comes in. The speakers sound great. I don't have the wooly sound you hear coming from most cars, but rather a good tight toneful base. I have also noticed that the 9000CD makes an excellent speaker box itself with little or no harmonics ( I have had trouble with the plastic between the rear light rattling horribly).
It is very important that you use a good material for the boxes. Many so called audiophiles claim that MDF or other such composite materials work well for speaker boxes and are better than plywood. That might be true if you use 1/2 inch CDX, but in reality good quality plywood is your best choice.
I used a plywood called baltic birch for my boxes. It's 3/4" with about 6 plys. Incredibly resistant to harmonic distortion! I bought mine from a local woodworker (home depot doesn't have it).
