A:AnswerYes, if you add it as an additional room. I have one next to my couch and one in my kitchen. Just add the rooms in when you want them activated and then cut it off when you don’t want them playing. But, the main volume control for your sound bar will not control the speakers volume. To control the volume use the app or then buttons on top of the speaker. Hope this answers your question.
A:AnswerYes, I bought the Sonos Beam (Gen 2) first and then purchased two of the Sonos One Gen2 and they are in sync wireless. Was easy to set up using the Sonos app. Movies, tv, streaming, it all works perfectly.
To recap, the Sonos ones do need to be powered through a cord. But do not need to be connected via a wire to work with the Beam. They connect wirelessly together.
A:AnswerAlexa is built you just need to down load the app to a smart device and connect the Sonos speakers. Yes you can stream YouTube or Pandora. I do not think there is a place to insert a memory stick.
A:AnswerI have the Sonos Arc, two Ones, and two Subs for my main tv and full Atmos surround. I have two Fives next to my record player in the living room, a portable Move in the Kitchen, and Beam in my Bedroom mounted to my TV. It’s beyond ideal.
