Oooohhh. "Anything over 80db or so for extended periods will result in some level of hearing damage". Damn! I'll do an hour or so at a time at a nominal out of 95 db. That's within OSHA standards, I thought.Along the lines of "let your ears be the guide"... I don't have experience blowing tweeters, which seems to be what everybody in this thread is talking about. The only thing I've heard of there is that any DC offset problem not protected against will surely blow a tweeter.
-------------------------
What about woofer damage? I have seen an underpowered woofer (home-made sub) tear right off the magnet. It only had a 70 watt Amber amp driving it, but going to my Carver PM1.5 (450 wpc), I couldn't blow a darned $8 radio shack driver to save my life, unless turning it up to the point where it would hurt my ears to listen, perhaps. Now all this was some 15 or 20 years ago...Now getting closer and closer to the point. With the speakers I presently have, I have 8" woofers. If the amp is not powerful enough, esp. in the right places, then those woofers will start to go really nonlinear in their travel. Wiggling in an awful way. That has to be bad, right?
But with a more powerful amp, and I would say more power (and speed?) for stability in the lower frequencies, the woofer travel stays linear with the same source - same SPL. And I'm thinking that's a good thing for the life of the driver, yes?
