I’d take that M2 in any room in a nano second.
It’s hard to say how a room would sound based on a picture even it looks less than optimal. I recently moved to a new house and while I now have a dedicated room (which sounds great btw), I find myself spending majority of my time in the family room as it is adjacent to the dining room and kitchen in an open floorplan. So I started thinking to put an audio system there with JBL or Magico and an integrated, along with a few acoustic panels given that the room seemingly has a lot of reflective surfaces. But having a kid less than 2 years old who grabs everything in sight relentlessly, my wife has concerns and the project is put on hold. So, I bought a Sonos arc soundbar to just get by these couple of years. To my surprise, the soundbar in this supposedly reflective room doesn’t sound bad at all. It only has a TV, a soundbar and an AppleTV. I’ll figure things out more when the time comes to actually install a system there, but at this moment it really doesn’t bother me to turn on the tv and enjoy movies or kids YouTube videos. The added bonus is I can also play Tidal, Spotify via Sonos and do occasional “hey google” to have some fun with the kid.
