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.....
Speaker wattage question
I'm new here, so I hope I'm posting this in the appropriate forum.
I am running KEF LS50's with a Parasound Integrated amp. The amp is rated at 165 WPC @ 8 ohms. The speakers are rated for 25-100 watts (and are possibly lower than 8 ohms according to some sources).
If pushed, do I risk damaging a driver, or will I simply get clipping?
Any help appreciated and please pardon my ignorance on something I'm sure is common knowledge.

inna2,182 posts08-11-2016 5:49pmWhy do speaker manufacturers put it in the specs when you can possibly drive anything with 1000wt of clean power? Inna, i think that you misunderstood. You can drive any speaker with 1000W/ch but it does not mean that you can crank up the volume indefinitely. If you do, you will fry the tweeter & eventually the woofer. So, you can use a 1000W/ch amp, just be careful of where the volume knob is & do not exceed the manuf's speaker wattage upper limit. it's not so much about "clean" power i.e. just because it's clean it wont damage the speaker. No, not true. |
