If the Amp is wired via ARC (HDMI), it will push the sound via the speaker posts. 

To my knowledge, Sonance doesn’t make ‘wireless’ speakers. All of their speakers require binding to speaker posts. None of them are self powered, either, but not being a self amplified speaker, they shouldn’t be. 

I’m not aware of any device that connects wirelessly to a asonos Amp, other than Sonos surround speakers. 

Ok. Thank you.  I agree but I find it odd the Sonos Amp can’t connect wirelessly to other devices that may serve as a source of audio since the Amp has a wireless function…..I suppose the Amp wireless capability is to only connect to the sonos system on my wifi network.  Only having an option to hardwire the Amp to the audio source outside the sonos system seems limiting.  Maybe it’s because you have to have the both video and audio feed thru HDMI from a TV for it to work properly…
