Bottoming out is when the voice coil hits the rear plate, and if it hits the rear plate enough, it can hammer it out of shape, and then your driver is ruined. By the way, don't run the sine wave test tones at loud levels for prolonged periods of time, sine waves are hard on drivers, it will heat up your sub in a hurry.

I had at it at -9dB master, not sure about my sub level though.. I'll check when I get home. I've watched other bassy movies (e.g., Cloverfield, Live Free Or Die Hard, Tron: Legacy, Star Wars II: AOTC, etc.) at the same level or higher, but maybe The Hunger Games had more low bass than others? I backed it down to -13dB master for the rest of the film after the bottoming out, and the sub performed very well

Yeah, I'm surprised when I hear some people say that The Hunger Games doesn't have much bass.. The aircraft scenes and the forest fire scene might be up there in my top 3 (if not number 1) bassy scenes I've watched..
