I agree 100% with bojack!
Some things in sound quality are not measured or hard to quantify. But that does not negate the value of things we can measure that affect the sound. I have not heard the X3 so the measurments are interesting to me since there has been more or less universal praise for them.
I am a bit taken back by 3 things about the measurements.
#1 the poor estimated in room frequency response (directivity issues coincide).
#2 the bass tuning…
#3 the lack of dynamic range. I have read people state they can play very loud but the data strongly suggests otherwise. This would explain why the X6 is made. I thought there might be something special with the tweeter but it shows heavy compression too.
Anyway that is my keyboard warrior take.
