A speaker so loud it can kill you

I was in the JBL factory test room for woofers in Van Nuys,Ca. and the volume was so loud you had both ear plugs and over ear protection. You could only stay in the room for a limited time as it was not considered safe. The room was used to test multiple drivers for reliability not sound quality. I was told that samples from the production line were picked at random for this test. It was beyond description.

I was at a Rage Against the Machine concert at the Universal Ampitheater and the whole place was shaking from the music and the crowd in the most unsettling manner. On top of that, the bass was so loud that I swear my hearbeat started to change and keep pace with the music. Also unsettlling.

All the best,
