Well we'll need to find out from Anthem just how that works when ARC is in use. ARC might ignore that Bypass completely, or do something more complicated with it. I just don't know.
But I'd be concerned that you might be getting no benefit from ARC room correction of the higher LFE frequencies -- which is a pretty crucial part of the Room Correction puzzle.
Keep in mind that there's no reason why the crossovers need be the same for the front speakers and the subwoofer. ARC handles overlaps in those for you just fine. Bass energy coming in on the main channels will go to the main speakers down to the crossover. A higher sub crossover doesn't change that so there's no integration issue on that front.
But with a higher sub crossover, the LFE bass energy gets to the sub without attenuation -- and ARC applies Room Correction as well. What I fear is that a low sub crossover but with LFE Bypass turned on may be restricting your ARC correction on the subwoofer only to the lowest frequencies.
I take it you are leaving LFE Bypass on while doing the Measurements, correct? I don't know that we've had any reports yet from folks comparing Measurement with LFE Bypass ON and OFF. I'll be curious to find out how ARC handles that.
ETA: OK, I sent an email to Nick on this. I'm not sure when he's back from vacation. If it's going to be a while, Piero may handle it with the ARC engineers. I'll let you know what I hear back.
