That's very doable using Wi-Fi and AC to power the speaker. How many have potlights where they want to locate the speakers?. How good can a speaker that small sound?
Incidentally, in the third Resident Evil movie, the zombirds were above our heads in an Atmos-kind of way with side QS10s located 11 feet away. This was not a small effect - it was very immersive. You could hear them rising up, flying around all over the entire ceiling and dipping down towards ground level. I could not get anything like that going with QS8s.
If I ever go Atmos, I'll be ceiling-mounting wired M5s.
