Will boosting my atmos speakers crossover cause problems?

[No_hair_left]

Just got some new atmos speakers however the crossover especially on the rears is very high at 150hz (aperion audio a5), my tiny sat speakers (monitor audio mass gen 2 sat) were getting the same crossover so pretty disappointed. Would lowering the crossover cause problems if I never listen at reference? I normally listen at -35 and the atmos speaker were calibrated at -4.0 after auddyessy.
First photo (red) is the front with subs with a 120hz crossover.

The orange and blue are the rears, no subs, psychoacoustic and then again with a 1/12 smoothing.

Seems there are -10 dips in there with 1/24 smoothing.

Given how little the atmos speakers are used in content could it be done?

I think the big question is why would you want to lower the crossovers? If the higher crossovers lead to you localizing the sub(s), then it might be worth lowering them. Otherwise you might get better experience with having them a bit higher.

One thing to consider is if you are using the "all speakers playing" function for music listening, then depending on the implementation it might be best to have lower xo's. In my experience it feels like most AVRs behave in a way that they send whatever is below the xo in each channel to the sub, which means that if you have 2 main speakers with 60hz crossover and 7 other channels with 120hz, then when all channels are playing it is almost like you would have system wide 120hz crossover, and you can easily end up localizing the subs. But this is only problematic when playing "9ch stereo","all speakers" or "party mode" functions, as in normal multichannel content there is usually very little content in the surround channels that could lead you to localize the subs.

That's the exact reason I want to lower them, 150hz is too high so the subs can be localised even in atmos content. Its odd because when I measure at least at 62db it looks like my top front atmos can probably go to 100hz and the rears to 120hz so not sure what is stopping auddyessy from selecting them. I just don't what it to boost them to the point where something gets damaged. I also think I read however is the xt32 sets them at say 150hz then setting it lower wont actually change anything as there is no filters below what it calibrates at, that's why its alright to higher it but not lower it.

I think it is totally safe to lower them to 80hz. You should hear if they start to distort. And for that you probably would need very loud levels.

No idea how auto-calibrations choose the cross-over points. Fronts they sometimes seem to get right, but I feel like surrounds never gets to set below 80hz, no matter the speakers capability.
