Oops... I mixed up some info
The X3100 always set my fronts and center as large. Not 40 hz... Since, as you stated, would imply small with XO. I always had to manually set them as small and set my own crossover. So my bad for the wrong information.
But that is a problem that audyssey has been doing for years according to the forums.
A better implementation would be to always set the front speakers as small as long as there is a subwoofer in the system that goes lower than the fronts, for example.
That would satisfy 99.9% of all use cases
My Towers are rated down to 38 Hertz. And they are about 2 feet off the front wall. And my sub (SVS 12") goes down to 23 hz anechoic I believe, and I have it corner loaded.
The RZ920 AccuEq had my fronts and Center as small, with a 40 Hertz crossover. I raised the crossover after Onkyo got done with its calibration.
So between the two, the Denon keeping my fronts and center as large, versus the Onkyo using a crossover that was too low in my opinion, which one did the worst job?
