I bought this thinking it would be awesome, and it was. I had it in a sealed enclosure and it would kick super hard. It sounded amazing. However, just today, it broke just like my buddies type r-12 did. I was in the car listening to music and then the bass stopped. I checked my amp and the amp was fine, but upon inspecting the subwoofer, I found that the spider had broken off and could no longer move. I'm starting to notice this trend because I know some other people who's type r has broken on the spider as well.
