Time is being ignored. I think werewolf explained it best...time is a major factor and time is not ignored, just for this example it is undetermined as of yet...//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif...im sure someone can crunch numbers and figure out the time allocated with the peak of a clean signal vs. the time of a plateau of a clipped signal, but i dont want to and probably cant calculate that right now...(i failed calculus //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif)
""DC" most certainly is an "average over time" ... but the million dollar question is, how much time?
Strictly speaking, the answer is easy ... over all time. But that's rarely very helpful
At the other extreme, it's reasonable to believe we can't average over a millisecond, and call that "DC". So what's a reasonable time interval?
I'll float a trial balloon, and suggest the following :
To be considered DC, the averaging time interval must significantly exceed all interesting time constants of the system.
These time constants include electrical ... the familiar "RC" time constants of first order fitlers, for example ... as well as any thermal time constants. Only when the time interval exceeds any "knowledge of time" that the system contains, would we be justified in considering a signal to be "DC"." - http://www.audiogroupforum.com/csforum/showthread.php?t=4332&highlight=clipping&page=4
That should end this tangent argument. I hope it does.The main argument was why clipping destroys a speaker. You and several others seem to think there are two types of watts, clean watts and dirty watts. There are only watts. The amount of power under the wave in a clipping situation is greater than that of the non clipped wave. This results in more power, but the same amplitude. The notion that the squared wave form means the cone stops is incorrect. Its the extra power that the squared wave delivers that will destroy the speaker, not the acctual shape of the wave.
