First is what you dont like about their sound?You dont have to change anything and the bass driver is a low distortion unit just compare it with any other speaker measured here.Making decisions just from a measurement and that was another model not measured in room is not correct imo.These are...
And also the FR is the easiest to deal with nowdays.Also a flat FR in low volume would make the speaker bass and treble heavy in high volume so too much fuss for nothing since you would always need eq.A cheap resonating cabinet or high distortion driver are bigger problems imo.
What speakers are you using?
The v1 was a better value and the measurements are fine even by todays standards.The new tweeter does not make much of a difference and the cabins are now outsourced.Their price can not be justified by any means.
So you would buy any speaker with flat fr is that right?
I did not write the part about amplifiers.What i find wrong is to judge the Brand from this model does this make them a better company: https://www.hifinews.com/content/atc-scm100se-loudspeaker-lab-report
I do not question the measurements but a speaker is more than fr measurements.Do all speakers with the same fr sound the same? Psychoacoustics and the room are a major factor too. As you say this is one speaker measured we need to see more of their speakers measured to have an idea of what is...
