Speaker wattage question

Harmonic distortion is present in all equipment to a (hopefully) small extent but in most clipped amplifiers this distortion increases dramatically. Your speaker’s crossover dutifully routes any of these signals higher in frequency than the crossover point to the tweeter, increasing the likelihood of damage.

well explained djohnson54. One point that djohnson54 made that i’d like to elaborate on - when the amp goes into clipping, the output music signal looks like it has lopped off tops & bottoms. The lopped off top comes from the fact that the output voltage maxed out to the B+ power rail. Anytime you have a music signal with sudden changes in amplitude it is like having a high frequency content in that signal. Sudden changes in amplitude = amplitude changes happening fast = high frequency content. So, it is this high frequency content that is dutifully passed onto your speaker’s tweeters (x-over is simply just doing its job). And, like djohnson54 wrote, the tweeter is not designed to handle high(er) power as there is not much hi freq energy but the clipped signal from the power amp does have high(er) power. And when this hi freq distortion power exceeds the tweeter’s power handling capacity, you fry your tweeter.....

Per the "danger of clipping" comments already seen here, the off-take is that you're more likely to damage a tweeter with an underpowered amp driven too hard than you are with an amp that has "too much power".

Why do speaker manufacturers put it in the specs when you can possibly drive anything with 1000wt of clean power?

If the speakers are rated to be able to handle 200 watt/ch continuously and I am using 1000 watt/ch amp, how do I know where those 200 watts are, speaking of volume?
