Where exactly are the ceiling speakers located in relation to where you are seated?

Hi GuitarSuperstar

Thanks for the reply!

So the TV and sofa are positioned  on the central axis of my living room. The two ceiling speakers are Left above my sofa, and other two are Right above my sofa. They are connected to the AMP properly. Left and Right channels are identical.

Here is how it looks like

This is what I would do:

Get an Arc or Beam and connect it to your TV via HDMI ARC. Get a second Amp and wire speakers 1 and 3 to it. Use the first Amp (speakers 2 and 4) as surround speakers with the Arc or Beam. The second Amp will not be used when playing TV audio, but can be used when streaming music.

If you want to save money, you can get a used Connect:Amp (Gen 2) to power speakers 1 and 3 instead of the Amp.

Wow thanks for the suggestion! 

Then will the Arc or Beam create authentic channels? Would this be an easy setup just natively using the Sonos App?  

Yes, both the Arc and the Beam create ‘authentic’ channels. 

Not sure how to answer your second question, it’s a fairly standard setup, very similar to any pother speaker, but requires you to connect it to your TV. 

An Arc or Beam with the Amp (speakers 2 and 4) as surrounds would give you a proper 5.0 home theater setup. And if you add a Sub or Sub Mini, it will complete the 5.1 setup. (NOTE: With the Arc, it’s technically a 5.1.2 setup because of the two height channels created by the Arc.)

Setting up the Arc or Beam and adding the Amp as surrounds is a very simple process in the Sonos app.

Question!

Is it possible to have a Sonos Arc with sub with 6 Sonos in ceiling speakers powered by a Sonos Amp playing the same audio in 1 room? Can't find any info on this online anywhere…also, if this is possible, can you change the effect of the ceiling speakers from, say surround to center? Thanks!!

Yes, kind of, if the 6 speakers are Sonance Architectural Speakers, otherwise you’d be maxed out at 4 or 2, depending on the Ohms they are. They’d need to be powered by a Sonos Amp, and set up as surround (stereo, not more channels) speakers. 

No, there is no way to change the center speaker from being in the Arc. The Arc will always be the left, center, and right, you can’t break those channels into separate speakers. 

If the ceiling speakers are all 8-Ohms, you could operate them from a single AMP, that is Bonded with ARC as a surround system, however, this would result in less than optimum surround sound for most listeners. As always, “best” sound is a personal opinion. Only one AMP can be added to ARC to drive the surround speakers. You could use a single AMP and a 3rd party switching/Volume control system to mute or adjust the Volume for speakers 1 & 3.

The sound stage for surround would be kind of weird in this set up though - from above instead of ear hight and from six speakers that are probably not all behind the listeners.

Since you question also seems to focus on the center channel, so probably speech, are you trying to achieve a solution for hearing troubles?
