[QUOTE="wolfey, post: 255769, member: 544404"] Thanks for getting mr. polk to clear things up tough guy, however i think it would help if he explained just how much distortion, and then ask him what usually causes it.. The distortion that is brought about in amplifiers with an increase in output is caused by "CLIPPING" which i stated originally. Clipping causes a distorted wave form in which the top if the wave is clipped off resulting in a non sinusidal wav.. the abrupt change is not good for speakers, i agree.(and yes it is at the threshold of amplifier output)... A clipped wave is an example of harmonic distortion.. "the inability to maintain linearity, resulting in the addition of unwanted HARMONICs, called Harmonic Distortion (see PEAK CLIPPING), or other tones, called Intermodulation Distortion (see COMBINATION TONES)." from [URL="http://www.sfu.ca/sonic-studio/handbook/Distortion.html."]http://www.sfu.ca/sonic-studio/handbook/Distortion.html.[/URL] Clipping alone does not ruin speakers however, clipping at levels near the threshold of a speakers input power does. There are lots of people out there that will tell you underpowering speakers is worse than overpowering speakers and its a flat out lie.. If clipping caused speakers to die then people would be replacing speakers every time they turned the volume up a little too high on all of there stereos.. and that just isnt the case.. Talk crap all you want but your the one ruining your speakers not me.. I havent heard anyone else complaining about harmonic distortion in there head units when they arent even using the head units amplifier.. all your head unit is gunna give is a signal to noise ratio if your not using its internal amp..
