Tone arm bounces

This very weird! When I play an album at a very high volume my tone arm starts to bounce. It will play albums start to finish at moderate levels with no problem at all. I have checked alignment and weight issues and they seem to be good. Clearaudio Avantgard table with Stradivari cart. The system is in a temporary room and may not be ideal. Could it be bass from my rear ported Watt Puppy 6's? Thoughts-----------

Sounds like acoustic feedback to me..Coming from the floors all the way back to your turntable amd arm...

This sounds like a problem related to the cartridge choice and arm compatability. I would check the effective mass of the arm as well as the cartridge then look up the calculator online that determines the resonant frequency. From what you are describing the resonant frequency is too high and not within acceptable inaudible frequencies below 15 Hz where the human ear can't recognize them. You interpret it as a bouncing arm but really the cartridge you chose isn't compatible with the arm on your turntable. Although I could be wrong.
