So I don't know if this guy knew what he was talking about or if he was just blowin smoke but I was told again recently that playing chords stresses out the speakers because of the conflicting frequencies you send through them simultaneously. Any truth in this? I searched & couldn't find anything for nor against this statement. I don't play chords often but I do some powerchords on occasion. I also play some other dissonant chords on softer intros to songs, usually no more than 3 notes at a time, mostly in the higher register. Just want to prepare myself for future repair/replacement of my speakers if this is the case. Thanks in advance.
