Because it's a waste of time to the guy who sales speakers and me, i find kind of worthless the '' store listening test ''. I when i started in the HiFi world i liked to test thing and waste my time, even with things like different combinations of dac/pre/powers, now i find it very boring, such things as distortion i find super annoyng, that why i dodge high distortion mid ranges. Because in my experience, even with EQ i can't make them sound to my taste.
Btw, Im not assuming, things that 1.5% 3rd harmonic is a bad thing, is not because myself writing things, things like that are know problems. As i said, the 2nd harmonic is not a problem.
Is not because '' I assuming the 2nd harmonic less a problematic '', it is what it is.
That's why the HiFi-Voice reviewer who measure the distortion point the problem, is not because i told him to wrote that thing.
In fact, lately another review who focus his measurement in the '' resonances '' find also in the exact same region, a ressonance:
Cabinet modes are well controlled but mild, high-Q resonances in the cones are visible at 3-6kHz
Lab Report Measured on the Reference 7K's midrange axis – its most likely listening position – the loudspeaker's forward response [Graph 1] indicates both a boost to bass (below 500Hz) and treble (above 8kHz). It's also worth noting that the –1.5dB dip just prior to the 3kHz crossover increases...

Both things,
the resonance and the thd, is what make me dodge that mid range from the old K series.
But for example the JBL 4367 only has high 2nd distortion/low 3rd distortion with no resonance.
Pd: In my case i got a 12dB boost at 88hz in the right channel
