Just thought I would chime in that I just picked up a pair of Brian's pre-built sealed box subs using Danny's drivers. I've had one for about two weeks now, and had the other one starting to burn in over the weekend. Tight bass, very very fast, articulate in the upper end of the frequency range, and they really play down low (and musically at that - no single note low bass!). I'm not sure yet if I'm much of an OB kind of guy, but the one of these in a small-medium sized room is a great addition to my music, and adding the second started to give my movies that "effortless" feeling that I was introduced to by the MFW-15 from av123.
Thanks, Danny, for helping put together a very versatile sub that fit my space better than many of the recently popular 15" driver box designs.
