the point isn't to get at some difficult to obtain holy grail tone you can only get from low MV, the point of the thread is to connect what i thought to be variable power amp resonances from speaker impedance to MV level, specifically regarding the power amp output EQ curve, so you not only get the distortion characteristic changes at differing MV levels, but also the output EQ differential at differing MV levels.
When you lower the speaker LF resonance parameter as you lower the MV level, it responds feels sounds e x a c t l y like a dual rec, bass goes down to nil and the scoop flattens out, to where below a certain threshold of MV level, there is no more low end resonance being added by the power amp, if you were to turn PA modeling off at that point, there is no further drop off in low end. PA isn't adding any low end at that low of MV. If the only reason it sounds that way in real life is from fletcher munson, then it's just fletcher munson. But since my understanding was that the power amp resonantes more at the speaker impedance resonant frequencies, it would make sense to me that the resonances would increase at those peaks with higher MV, resonance becoming more pronounced with increasing MV, having the same effect on output EQ as turning up one of those Mark V EQ preset knobs with the fixed scoop shape, or increasing the Triaxis dynamic voice parameter, a dynamic scoop shape that increases with prominence along a gradient, applied to the output EQ. But apparently that's not the case. Apparently the power amp distorts more along those peaks with increasing prominence with higher MV settings, but somehow the output EQ is unaffected by the same speaker impedance curve peaks. Must be entirely fletcher munson, combined with the 0.000001 micron edges of a MV pot causing treble bleed in an amp, settings that obviously no one except bedroom superstar would gaf about. The whole point is there is an EQ gradient available, that right now is only manually adjustable with Speaker LF resonance, and coincidentally has the same curve as fletcher munson. Speaker impedance curve does not make PA resonate more with a differing output EQ with increased voltage (current) output, fletcher munson makes it sound like that in real world since you don't have an output level control to keep your face attached, makes sense.
If i could measure stuff I'd measure a sweep at low MV, then measure a sweep at higher MV. The definition of resonance to me is increased FREQUENCY amplitude, I don't see how in the world you would not have increased FREQUENCY output at those speaker impedance peaks with increasing r e s o n a n c e. But apparently the resonance amount doesn't increase with differing MV levels. Then why does the BASS distort first at that peak?? The resonant peak affects the PA distortion with increased MV level, but somehow, the RESONANT peak doesn't affect output EQ, in any capacity, at all, ever, with increased MV. That's where my brain keeps itching.
