Re: Tech crew blowing speakers too frequently...
A quick search on google gave me the following info. A clipped sine wave (square wave) isn't DC as it doesn't have the properties of DC. Whatever that means.
The propeblem with clipping is that it make sthe speakers try to extend all the way to the front. Then after being there for a while jump all the way back. This causes stress to the speakers. It also heats the voice coils. When the speakers heats up, the impendace grows. This makes you push the fader even more thus heating the speaker more. This can also be caused by feeding signals (frequencies) above or below the speakers production range. Like 30hz to a mid speaker capable of 400hz-3khz. Amps should have DC protection. DC damages speakers as it has some properties of a clipped sine wave (square wave).
I can't believe i wrote all that ;)
