Is Clipping an amp always Audioable?

I should amend my answer: Clipping sounds like s**t if there's enough of it to hear. But, as Gs rightly points out, the occasional clipped peak isn't a problem at all. One study I know of found that clipping becomes audible if it occurs more than 1 percent of the time.

I'll stick to the second part of my answer, though: Clipping doesn't damage speakers; juice damages speakers.

It is true that too much power may damage a speaker but it is not likely if it is clean power. Distorted power or clipping is much more likely to damage a driver.

Thanks guys, I feel tons better. I have one more concern. This was done during the break-in period. Could I have caused damage in that regard? I have heard not to push a speaker too hard during break-in. Is there any truth to this at all? If so, what could happen, would the results be immediately apparent?

Thanks again guys

Too much power, clean or not, is *very* likely to damage a speaker. Distortion might mean extra energy pushed to the tweeters, but it's the energy, not the distortion, that does the damage.
