Re: EQ sweepingThis is very true about harmonics. Feedback and room resonances often have a noticeable component at the 2nd harmonic (2x fundamental frequency) and sometimes a bit at the 3rd harmonic. I used to notice this a lot during the days of using a RTA. Sometimes it will be the harmonic that is actually taking off and resonating more. That is why the cut at 1/2 the frequency will often tame it up the line. The problem fundamental resonance is often actually lower and is exciting other things at the harmonics. I believe that is a correct explanation. I have not taken physics in years.
