[QUOTE="bball09124, post: 4786242, member: 573352"] Finished a new box this morning, I was doing a practice run on the way up to Florida State Finals, holding a 143-144 on my meter (140-141 on the TL) sealed up. 20 seconds into my bassboxing run (60 second avg) volume drops, I turn it down. Wait til I get to the show, pop the trunk, one subwoofer is stuck at its peak excursion. I didnt snap a pic before I pulled it out, but it looked as if you hooked the coils up to a bank of 9V batteries. I pushed as hard as I could on the sub to get it back down and it did not budge. No one on my team or who saw the sub as we were tearing it down had ever seen anything like it. We take a razor to the cone and spider, this is what we find.

The pole has not always been shifted, it played fine previously and there was absolutely no rubbing or scratching. I did not hit a pothole, or anything, to knock the pole that off center. The other 10" SX sitting in the box with it was just fine. [/QUOTE]
