What is a SonosBar?

In order to run the ceiling speakers as surround speakers, they’d need to be driven with a Sonos Amp. The Sonos Amp would wirelessly connect to your “SonosBar” using a 5Ghz signal. There’s no need for a physical connection between the “SonsoBar” and the Sonos Amp. 

Hi all.

im new here and have an extension being built. While the ceilings are down I have been considering a Sonos set up for this space. 
 

I am hoping to achieve a tv surround sound set up tied in with the option to listen and stream music using all speakers.
 

I think I have narrowed this down to the following Sonos set up but I’m not sure if this would actually work in reality… An Arc, Sonos sub, x1 Sonos Amp and x2 rear Sonos in-ceiling speakers.

Is this possible? If yes, what do I need to do or get in addition to make it work?

Im looking for a simple answer as I’m a bit simple🤪.

Thanks guys!
