[QUOTE="joetama, post: 1765199, member: 564641"] I disagree, most amps will not let you clip them bad enough to get true DC, however clipping does cause DC. I have seen a PA loudspeaker catch fire and a cone leave the basket tearing the surround and the spider because of true DC, it may only be for a few milliseconds but it’s still DC. The reason the guy in the other forum could turn the 'clipped' signal into a sin wave is because of the shelving effect in a cross-over, think about it. You’re not going to agree with me I know but, who really cares anyway. Everyone has his/her own opinion of things. Have a look at this article. Also, read the forum link with it, it's what this discusion could turn into!!! [URL="http://sound.westhost.com/clipping.htm"]http://sound.westhost.com/clipping.htm[/URL] Just a side note, it's generally just not a good idea to clip anything. If you need it louder buy more speakers, if your amp wont power them get one that will. Head room is something that I always learned to be very important. Here also is a little tid-bit from QSC's history. "...Over the next five years, reliability became synonymous with the QSC name thanks to several technological advances developed by Pat.
