I'm still kinda hoping for a part two...
One thing about the "everything has a resonance" bit-- the beauty of broadband bass trapping in recording studios is that it really doesn't matter much what kind of space you're in, because the whole idea is that you're just sucking up *all* of the resonances that could potentially be problematic.
Trying to create a great acoustical space for concert performances, or a world-class live room is almost certainly outside the scope of DIY home studio advice. But getting rid of the honk mud, and phasey, nasal mush in most residential spaces is pretty easy, and can be really cheap.
In movie theaters, "the walls are soft and dark" in the words of Camper van Beethoven, and they are made that way with very heavy curtains and absorption whose purpose is to make sure that the only sound the audience is hearing is sound from the speakers, not from reflections or surface resonance. Building a movie theater is not cheap, but it is much, much simpler than building a stone cathedral or orchestral concert hall.
