Bought this to complete my setup! Previously had the Beam and two One's and thought that was amazing. After reading some reviews it was clear the sub eventually had to be bought. Made the choice sooner rather than later and couldn't be more happier I did! First movie I watched was Ready Player One and it felt like a new movie I was watching since I had seen this so many times! The bass just kicks in when needed. It takes the pressure away from the beam and One's with bass. Volume has more depth and feels alot more balanced. Setup was extremely easy and a matter of opening your Sonos app and having the bass recognise through your current wifi. Would recommend this to anyone that appreciates good quality sound.
