No, unfortunately not. The Arc can not be used as a center channel, it is always is right, center and left.

You could conceivably go with two Sonos Amps, bonded together, and you would get an interpolated center channel, but the you wouldn’t have the Arc. 

Having the TV sound come from above is not a good idea, it should appear to originate from the screen. It is also not necessary to use in-ceilings for FL and FR, since the Arc already provides those.

Hi, 

I’m setting up a 5.1 home theatre using Sonos Sonance speakers. It seems they are only sold in pairs. Any suggestions on how to buy one front centre speaker?

Thanks.

Do you mean a Sonos soundbar as that’s the only devices that have/operate a HT front centre speaker. The options available are:

• Sonos Ray
• Sonos Beam
• Sonos Arc

Note: A ‘pair’ of Speakers can be bonded to the above for use as rear HT surrounds, often alongside a Sub, or Sub-Mini.

 I’m thinking of an in wall speaker under a 70 inch TV as everything is built in.

Sonos do not make a front centre-only HT speaker - they do make soundbars with all three front channels built into those.. only thing you can add to a soundbar is two rear channel surround speakers and Sub(s).

If you want in-wall speakers, then you can use two Sonos Amps, one for the front L/R channels which uses two speakers only. (The front center channel is a phantom centre channel) and the second Amp links wirelessly to the first for the two rear channels. Upto two large Sonos Subs can be added to the setup, but one must be a Sub (gen3), or you can add just one Sub-Mini instead.

Thanks Ken. Very helpful.
