URL: Tom Nousaine quote on clipping |
|
From a Tom Nousaine post at the link below (not that easy to follow the very long UseNet discussion on the danger of clipping -- I read the entire thread and
I can't say there is agreement ...
but Tom does test speakers for a living,
so I'll assume his opinion is an expert opinion:
"The speaker never comes to a stop.
This idea is a fundamental misunderstanding that comes from that "DC" argument.
I think it stems from the misunderstanding that the analog picture of a sine wave or square wave as it appears on the face of an oscilliscope is actually the 'signal' and the flat top is some kind of DC component.
That picture is just an analog idea or representation of the sound or signal.
As Mark began by saying (in his paper) there is no DC component ... he's right .... and therefore the cone never stops.
Another part of the analysis that tends to get forgotten is that the tweeter's impedance will be rising as well and the only important harmonics will occur around the resonance area of the speaker.
All this is not a criticsm of the work (paper).
The idea is well taken and right on the money.
You won't protect your speakers by using a larger amplifier.
It will just burn them out as fast by supplying
more power no matter what the condition
of the signal."
