Chops, I don't know his status on in-stock but Rythmik sells complete single driver sealed subs using Danny's parts if DIY isn't your thing at the moment.
Danny, as we are (sort of) on the subject of big OB drivers, did you ever get a chance to check out the BMS coaxials mentioned last time the subject came up? If so, any thoughts?
Also, for folks who have the x-statik, is there a significant break in period before they really open up to what they are capable of? I got a chance to hear them once a long while back and what I heard really doesn't track with what nearly everyone has to say about them. . . maybe it was the system/setup they were in, but I just get the feeling I didn't have the chance to give them a fair chance.
