Is this 62.5 volume relative to a 0-100 scale?
Deff check to see if its the sub or just something around it rattling. I am trying to think of anything in that movie that really provided any crazy bass. Its been awhile since I seen it. Does it do it at other parts? Reason I ask is because my SVS made some pretty nasty noises in Enders game on the launch scenes and just likely over excurded the sub. I never heard it on any other movie and turned down the gains after that happened.
Also maybe pop the sub out of the box and see if anything came off inside.
