Since I got my 16-46+ about a month ago, I've been happy with it, but I was surprised how easily it bottomed out. Seems like whenever we got the joint jumping, it was running out of steam. Well, it turns out that the joint was jumping-literally! What I thought was a bottoming subwoofer turns out to be a subwoofer that was jumping straight up and down, and as it clattered against the floor, it sounded like it was bottoming out. I slipped a piece of carpet padding under it, and now it sounds beautiful! Louder, deeper and better. Of course, I'm not saying the carpet pad made the sub sound better, it just plays a lot louder before it sound stressed out. By the way, the movie Joy Ride has some wonderful low-end. It's a really well done sound design.
