Ayone know the wattage used at a Rock concert?

Ah yes, the A7. The band house I lived in back in ’71 had a pair of them (the bands PA, of course) in the living room as a hi-fi, powered by a Fender Showman head. Had to be careful with the volume control---the A7 was so efficient, the 65 watts of the Showman could drive them to insane SPL at the flick of a wrist. Those A7’s plus a particularly nasty Fender Twin Reverb (with a pair of JBL D120 drivers) really did some damage to my poor ears.

And Charlie isn't a "pounder". Now Keith Moon, he really hit those drumheads! The only other guy I saw/heard who played that hard was Buddy Miles---he was a very big and strong guy.

I saw The Who and AC/DC, but my loudest show was The Ramones in L.A. in the 90's. I can't remember the venue, but the room was all cement, the sound bouncing off the walls from every direction forever. I got SUCH a headache.
