Hmmm. That's not what the published analog bass management matrix shows:

Notice that "Fronts SM" indicates that a "full range" signal should be sent when "bypass" is selected.

Perhaps there was some miscommunication. Every time I've spoked with Scott about this, he's said that they're working on it.

Furthermore, the high pass filter applied to the mains does not appear to be related to the crossover frequency applied in the OSD. It seems to be applied at about 100 Hz regardless of crossover setting. That, in and of itself, makes the whole discussion moot.

I think there must have been some miscommunication. Perhaps you guys were talking about digital inputs...
