I think a single crossover point is largely better anyway.
The sub has to integrate with multiple speakers - the difference between say 70hz and 90hz is huge when it comes to a crossover blend between sub and speaker - so dont let that put you off.
By this I mean if you have different speakers at different crossover its impossible to get a perfect blend with all of them
I always try to recommend the same crossover point for all speakers, and also usually recommend they be set to small as well (even large speakers) at least for normal 5.1/7.1 systems anyway. For Atmos type systems, I think it would be fine to set the height speakers to a different crossover, as they're most likely not going to be exactly the same as the front speakers.?
So you can have a higher crossover for the fronts something like 80 - 100hz which gives a real punchy sound but run a lower crossover for the rears of say 60hz so the rear channels have a bit more weight / fullness to them then they would at the higher crossover.
This is just a theory as I cannot do this in my setup either - whats the thoughts on this idea ???
The problem I see with that is that you're making the assumption that the rear speakers are going to firstly, be capable at 60Hz, and secondly, be big enough to be that capable, which most rear speakers won't be, as they tend to be smaller than the front speakers.
