I actually just threw one of my 12's back in the other day. I had pulled it as I was going to drop it into my sealed enclosure but it turned out the cutout wasn't large enough for the sub . So no sealed results for now but I plan to build another box for it or possibly the pair sealed. Still really enjoying the single 12 ported though. Gets plenty loud enough on its own for daily listening and sounds real good doing it. Its not all upper bass or super low bass like some subs. Does a good job with most frequencies in the sub bass spectrum. I would like to take a few good vids when I have some time. These things have some really good throw. May try one of the 15's out when they are released as well or maybe hold out for the threatcon 4
