You cannot add any more speakers to the front channels with the Sonos Arc.
This is what you can do with your setup:
- Sonos Arc
- Sonos Sub
- Two Sonance in-ceiling speakers powered by a Sonos Amp
This setup would give you a 5.1.2 system. The only other speaker you could add is another Sub, but make sure one of the Subs is a Gen 3. Two subs would give you a 5.2.2 setup.
Ok cool
only need one sonos amp for this setup right
separately one pair per additional sonos amp for music in other rooms right ? ( one amp for 3 sets but al have same music same volume )
Oh with this setup mentioned by i can listen to my music on my phone through apple play
Yes, you only need one Sonos Amp to power the two rear surround in-ceiling speakers.
If you want to add more in-ceiling speakers in another room, you would need to add another Amp.
NOTE: The Sonos Amp has been designed to power up to three pairs of Sonos Architectural speakers on a single Sonos Amp.
The Arc and Amp are both compatible with Airplay.
