Conclusions
ATC is another "PRO" company producing hi-fi speaker. My impression of any such company is that they would produce speakers that would have a neutral and balanced frequency response and hence tonality. I can't fathom how they would produce something like the SCM19. The results are so poor that I am suspecting my measurements must be wrong. But then the listening tests confirmed the same.
I read that the new version uses in-house tweeter. That seems like the wrong problem to try to solve. They should fix the woofer first.
Needless to say, I can not recommend the ATC SCM19
