Mark,
Yes, indeedy. He's a really interesting guy and his ears seem to still be in good shape. He told me he can be seen scurrying about the stage in a DVD reissue of an Isle of Wight concert, but I've forgotten which one. I'll find out.

Any chance this is Bob Heil? He did concert work for several notables including the Dead. He may still be doing that sort of thing, but I know him mainly from ham radio where he has an impressive line of microphones and other audio gear. Good guy!

Hi n8wrl,
No, he's not Bob Heil. But, interestingly, Steve is also a ham radio buff who has a system in his Mini Cooper. So far as I know, he does not do concert sound anymore. He develops custom "codes" for digital algorithms.

Hi,
Ian Colquhoun did some fixed-tone SPL measurements on the M80 in our anechoic chamber yesterday. He reports that by placing the mic between the tweeter and midrange drivers 10 inches away he achieved 120 dB SPL at 1 kHz at 15.15 volts input. The distortion was well under 1%.

Or, at least he would have been, if his ears hadn't fallen off his head moments before!

Thanks Jack!
But currently, the ratio of PMs I'm receiving are 6-to-1 in favor of me posting less!

Trevor, excellent information from Alan describing Ian's test, which again illustrates the quality of the M80s at a level approaching the threshold of pain. Also noteworthy is that the 15.15 volts input used equated(P=V[squared]/R)to only about 57 watts. The problem apparently is the size of speaker that you can fit in your testing chamber.
-----------------------------------
Enjoy the music, not the equipment.

WOW!!!! The M80s must be super rugged.
Not a chance that I would listen to mine at that level.
