Does everything have to be all in one, or are you open to exploring passive speakers and a receiver?
Since this is in Homelab, I’m assuming you have access to a 19” rack. You could rack mount any amplifier (I like crown amps personally) and then feed either a Bluetooth or Raspberry Pi using a line/headphone amp. That also gives you the ability to continuing adding amps to feed more speakers around the house. That’s my homelab answer.
Home theater answer would be to look at a home theater receiver.
At the same, does “painting our selfs into a corner” loose having true ending to stories?
Constraints and limitations drive creativity, but you have accept a final product at some point and move to another universe/story.
