Bass integration will always have room dependency no matter the speaker, and some setups aren't easily solved. In one scenario it will be set and forget with others being laborious.
The AMT to mid integration which had been an issue on earlier some GE designs has been mostly resolved in the Triton One and + series. Looking at figures from the Reference One. At most there is a small vertical response dip at the extremities, so maybe sitting rather low might have an impact. The upper treble is just a tad bit elevated when listening directly pointed at you, but that is the designed intent and mainly done to compensate for in room response when setting a wider toe in. In room, it can measure well and the dispersion below the upper treble is decently linear and even through wide range. It shouldn't be that hard to dial in the treble. If you like your treble shelved a bit down, it may sound a bit brash with a recordings that are bit hot themselves. I also wouldn't pair this speaker with amps with a forward or lean sounding. Prior models did have some of the same design for the tweeter response (a bit more from what I can read), but the added suck out they had in the mid-treble hand off made getting setup right a tougher job. Not so much with latest stuff. I find the worst offenders are those that have a mid treble flair since our hearing is more sensitive to it than the upper treble.
From a measured perspective, only have gripes with some low level mid range distortion and some AMT linearity at high volume. Still, these are some very good figures.
