I'm thinking of expanding my Sonos collection with one or two Sonos One SL, but I'm not fully sure what the capabilities/interoperabilities of these devices are.
In my living room, I have two Play:1's as a stereo pair. That is the extent of my Sonos products.
1.) Can I add a Sonos One SL to this group to get fuller music in the living room? Will the music optimization take all three speakers into account to make the music as good as it can be? Would it be better if I had 4 total (e.g. two L and two R)?
1b) If I can't add it to the group _per se_ can I create a new group "livingroom2" and play synchronized music to both zones at once?
2.) Is the above the same as adding it to a stereo pair? If it is not, is it possible to make a stereo pair with Play:1 and a Sonos One SL? (I believe it wasn't possible with Play:1 and Sonos One.)
3.) If I buy a Sonos One SL, that has Airplay support, and it is in a group with the two Play:1's, can I airplay to all three?
3b) If I buy a Sonos One SL, that has Airplay support, and it is in a *different* group than the two Play:1's, can I airplay to just the Play:1's?
Thanks for your help,
