Greetings from Mèrida Mèxico, I`ve got in my SYSTEM 2 Sonos One (SL and 2nd generation), Mini Subuffer and a Ray sound bar. I looking forward to get a 300 era, I know that it`s not compatible with the minisubbuffer. As an option if I get it, I think that the only one is to create a new system for the 300 era and play them at the same time, Can somebody give me another advise?
