If you're correcting anything above the frequency range affected by room interaction (approximately double your room's Schroeder frequency) you're, excuse the parlance, royally fucking your speaker voicing, so expect that correcting anything more than double your room's Schroeder frequency is more likely than not to be, as you pointed out, catastrophic.I previously had a Lyndorf which comes with a calibrated microphone to run their RoomPerfect. I have tried this in my old home and my current house. The results were catastrophic in both cases and basically the same as those rendered by my current Ultra.
If full-range correction ruins your sound, try again limited correction to no higher than about 350Hz.
