Is the Home theater extension, 2 One’s and a mini sub, worth getting as an addition to my current Sub, Arc, and 2 Ones?

You can't add the extension to an already completed home theater.  The only thing you can add is another Sub Gen 3.


SONOS ARC can only work with a single pair of ONE’s used as surrounds. You could use a second pair of ONE’s as another Room. I don’t recommend attempting to incorporate this new Room as part of your TV watching.
