Hi, i have recently bought a play 5 and love it. However i would love to get the stereo effecr. I was wondering if it is worth getting two play 1's to go with the play 5 all in my room. So the play 5 would be at the front, and then the two play 1's would be behind, making the stereo effect. Would this work? Im not sure how the grouping feature works in the sonos app.
