Used as the lounge sound bar and can say it is one of the best home theatre systems I have ever owned. I bought a sub for it a year after the purchase and it took this system to another level. Easy to setup and use via the Sonos App. Multiple music steaming/radio stations available via the app. The playbar can be positioned on top of a tv cabinet or mounted to the wall via sonos wall bracket (sold separately) If you want 5.1 you can use either the play:1 speakers or the new one speakers which are easy to setup.
