Daniel, does your bass sound too bloated if you cross over above 40 or 50?
Yes. Whether it's an issue with the sub or with the room nodes at those frequencies, I can't get a satisfactory blend with smaller speakers. The Onkyo AccuEQ software has the M5HP crossed over at 40 Hz and Angstrom Modular Six Center at 50 Hz, and it sounds right. My Kanto Yumi and Angstrom Omega II 200's cross over at 80 Hz and 110 Hz, and it's too easy to localize the sub. That's probably why I'm dismissive of the THX recommendations of 80 Hz for all loudspeakers.
I'm fortunate that I've been able to find a configuration that's dialed in for all 4 of my seating positions with minimal hot spotting. But it took a year of tweaking before I nailed it.
And my sub is reminding me to feed it contact cleaner to make it to its 28th birthday.
