I have 2 one SL one in Living room and 1 in bedroom , I just setup both in stereo pair mode in bedroom and I'm impressed with sound clarity and room filling sound after tuneay. I will recommend one SL for multi rooms or stereo pair mode.
Pros: Different Music, Different Rooms, Easy to Set Up, Expandable, Free Control Options, Streams All My Music, and More, Superior Sound, Wireless
If you are not technically oriented, very difficult to program without a tech person and while he was helpful , he only got me thru the basic set up. Primary reason I bought it was to connect to my Alexa and have them both play at the same time which I understand I can't do. Oh well, I will need to find a teenager
I bought the pair to add to my Beam in my study/workout room to make a surround sound system for the TV in there. They were very easy to set up and work flawlessly, adding richness and spaciousness to the sound in this small room. It's also true for the sound when I use them for playing music there. When we remodel our kitchen I may move them in there to pair with a SONOS 5, but they work so well in my study that I probably won't want to give them up!
Pros: Easy to Set Up, Expandable, Superior Sound, Wireless
I got this for surround sound purposes. They sound great at times. They crackle a lot while listening to music or while watching movies. Next thing I'm going to try is hard wire them. But I don't think that's going to help though.
