question about spinorama——the effect of the high frequency

[ambition]

When I used spinorama to evaluate the sound quality of the speaker, I found a problem, when the lower the high-frequency response of a device, the higher the LFX, and the higher the SM , which leads to some high-frequency obviously defective devices, using spinorama can evaluate higher scores.

How to explain this problem, and is there any other way to avoid it

Quoting Dr Toole ...

I just dipped into this thread and have a request: please, please stop putting any reliance on the calculated "scores". Learn to interpret the spinorama curves. That will have to do until we have an "educated" AI version of sound quality prediction. The ratings that were calculated by the Harman research group were done to prove a scientific point, and that done, they ceased to be used even by the people who created them. We rely on visual interpretations of the family of curves.
