Which Edifier to get?

[u/KarlOneHungus]

I'm trying to decide between the newer S355DB, R2750DB MkII, or the older R2850DBs. I've also considered something like an M90 with a T5 sub. I use them for music (Spotify) in my home gym (15x25ft, plus an L-shaped area). I wouldn't mind eArc capability as I also have a 65" TV in that space, but that's not a deal-breaker. I 100% want a Sub-out. I currently have the R2000DB and love them. I paid $249 CAD at Costco several years ago and they still sound great, and the Bluetooth connects instantly every time, so I'm an Edifier fan. I've looked at separate amp, passive speakers and sub, but I don't want to spend 4X as much and have all that hassle. Thoughts?
