Thank you.
I have talked and worked with Edgar many times. How he manages to do all that he does is beyond me.
He is a human dynamo. Nobody I know talks as fast as he does!

I have the Bacch4Mac with the Babyface Pro + and room correction output through Roon.
Is there anything more to be dome to activate the room correction other than to run it with the microphones in your ear in the listening position?
If I understand you correctly, a point source box subwoofer is just fine to use with the Poporis so long as  the subwoofer and Popori's output frequencies don't overlap.

Yes, Edgar is quite something else.  You will need to be sure the settings in the ORC section are correct for what you want to do.  Very often the default setting are fine, but for the Popori by itself, set the low correction limit to 40Hz.  Also, allow 4-6 dB of boost.  When mating a sub have its gain set high.  ORC will trim it back.  Also have ORC set to the low limit instead of that 40Hz.

If you have the ability not to overlap by using two separate  crossover frequencies, I have found that to be best.

What I have found is when the main speaker radiates bass in a figure 8 pattern, like here, then you really really want to have the sub match that pattern.  Box subs stick out like a sore thumb because they radiate like a pulsing sphere.  Makes perfect integration almost impossible.

Has not been my experience and I cross over well above 100 hz, but I may not be as fussy as you with all of your show experience.  That's not a dig, but an honest assessment.
The sub used is probably more important than the pattern, and also the implementation would be critical.
