I read a lot of people here talking about "underpowering" being bad for speakers. Is there really such a thing. Underpowering is really just like having the volume down on a more powerful amp. How is that going to damage speakers?I can understand when you have to run a small amp full out that the distortion might hurt the speakers, but if you don't overdrive a small amp, then is that going to hurt anything? Say if I run a 300 watt speaker with a 100 watt amp... If I only ever turn the amp halfway up and never overdrive it, will I damage the speaker? I am usually pretty good with this electronic stuff, but has anyone really hurt a speaker by underpowering?
