Now that I've lived with this setup for a day, I didn't realize just how bothered I was by the clutter of the electronics. I have some frosted glass adhesive sheets I can use to laminate the tempered glass shelf to hide the nest of wiring behind the AVR.
From what I've gleaned from reviewers, even Samsung, Sonos, and Bose's flagship configurations are no match for the Sennheisser Ambeo Max with an external sub for music. You can't DSP your way out of needing larger drivers and cabinet volume. The Axiom Epic Mini should have more than a fighting chance of coming out on top.
