Well, I forgot to look at your link. After doing so, I assume you're talking about using the TC9 10" 2565 driver? Where are you getting .35ft^3 from? In a .35ft^3 (9 liters) sealed enclosure this driver will have -3dB point of 75Hz. IMHO, this driver is useless for anything other than car audio applications unless you plan on using an LT circuit or some other form of EQ to extend the low end response. Even then, I would say you'd have to use multiple drivers, at least 2-4, to make it a worthwile endeavor.
I don't mean any disrespect, but I have to ask again, do you have any knowledge of subwoofer design?
