Thank you for your answer Christoph, and for your amazing gear.
Yes, I read the part of the manual (IRTFM )about the Kone before posting and tried both. It seems you are right, the DXR12 is brighter and that is what I am used to.
As you mentioned, the phone recording is not really "judicable"...
A quick question though, what is the thickness of the Kabinet please ? Mine is 18mm thick.
The Kabinet has different thickness of 10 to 20 mm.
But the thickness does not have an influence on the highend frequencies.
Have you tried the Monitor Equalizer?
