Can't really give you an answer on how loud that would be in dB's as ever room is different in size, speaker placement is different, receivers are different, listening habits are different. Also, some music has larger dynamic peaks that can jump 15-20dB's and put the receiver into clipping.
It really has more to do with the Yamaha circuitry and protection limiter. You will not hurt the Yammy or Axiom speakers. Just know that if it shuts down all the time it is either not compatible, or you have the speakers wire strands touching. Most likely you will be fine.
