A:AnswerSonos Era 300 speakers can be bonded as surround speakers with the Sonos Beam (Gen 2) and Arc for a full, immersive home theater experience. They are not compatible with the Sonos Ray or the original Beam (Gen 1) for surround sound
A:AnswerYes, but you can not set them up as a stereo pair.
If you are just looking to play music, I would recommend going with a sonos five or 2 era 100s if 2 era 300s is out of your budget. Or get the 300 with the goal of getting a 2nd one down the road.
But yes, to answer your question in a bit more detail, you can have many many speakers playing together with sonos, but the move cannot be 'grouped' with a non-move. I have a move 1 and a move 2 (cannot set them as a stereo pair, either, btw. Has to be the same move model), one is in my dining room, the other is in my office, and they play flawlessly with all of my other sonos speakers. I have at least 1 sonos speaker in every room and every space big enough to justify having one in it and they all play together nicely.
A:AnswerYou can pair any 2 sonos speakers as a stereo pair if they are the same model. You can also integrate the 300s into a surround system with the arc or arc ultra, and you can add up to 2 subs.
Just buy it.
A:AnswerWorks with mine. One issue I initially had trying to use these as rears wiht my Sonos arc was consistent dropping of sound from the years. Turns out my arc was too close to my router, moved router a bit, and now all working well. I use eero 6e wifi
