[...] a room that is much larger than the speakers themselves.
I sure hope so!
That being said, if you were talking about the Virtual MR1, I just tried at 1Khz, 0db: (note: they knob has not markings, so the position is not entirely accurate)
Does that give you a better idea? For music, 11:00 is alright, 12:00 is good and 13:00 is excellent in terms of clarity and presence. I did not try it at 14:00 and more for the test signals as the neighboors might still be sleeping.
