Loooooong review (for my limited attention span, no, I'm not looking at my phone).
Lastly he says, "The problem, I suspect, is that in the crossover region, some combination of the dipole bass side-wall cancellation and the inherent beaming of a large driver at the top of its pass band shifts the off-axis tonal balance towards the wider-dispersion treble." Something is amiss (for him) and I will reiterate my use of DIY Shakti Hallowgraphs as a way of shifting the soundfield, depending on the recording, to allow more hall like openness or directness, depending on taste. Also, it could be that he needs to live with these for a while (as all speakers do) and adjust what he can when he can, including ancillary equipment.
Or, he could could be right, I'm just not hearing what he's describing (different rooms, for different folks).
