Wiring a SONOS surround sound system

Dear SONOS Enthusiasts,

I plan to purchase and install SONOS equipment to create a surround sound home theater in my living room, which measures 16x24 ft (please see the attached layout). Given the Samsung OneConnect HDMI ARC already wired to the SONOS Amplifier, I have two specific questions:

  1. Can I connect the SONOS Sound Bar to the TV via HDMI, as shown in the attached figure?
  2. Can the SONOS SUB connect to the amplifier wirelessly over Wi-Fi?

If the answers to both questions are yes, will I be able to create a surround sound system with both wired and wireless connections?

Thank you for your assistance!

Best,
CJ

The HDMI ARC from the TV must go to the soundbar. AMP will be added to the soundbar as the surround amplifier. There will be no audio connection to the surround AMP. Network connection to AMP is optional.

I’m suggesting wiring for an additional, future pair of speakers near the plane of ARC. Actually, two pairs would be even better. One pair as L/R on the TV wall and another in the ceiling near the front wall.

Your latest plan for the rear is OK. If your ceilings are high, consider a pair of wall mount speakers behind the couch.

I have an 1960s home with 7’5’ ceiling height so in-ceiling speakers are reasonable choice I think.

My final point would be that if you think you will want to listen to music through just the Sonos Amp and not have the Arc involved, this isn't easily possible. Without undoing and re-doing the setup of the Amp as surrounds, there is no way to use the Amp (and it’s extra inputs) independently of the Arc.

Hi @Ian_S — If I read it right, with this setup it is not possible to listen to music only (TV off) using the Amp. Correct ?

You can listen to music, but it will play through all the speakers (Arc and Amp), with the Amp speakers configured as Ambient (lesser volume) or Full (full volume).

Got it! Do you still have surround sound when TV is off in this case?

That depends if by TV off you mean Arc off as well. If you want to use the Amp on it’s own to listen to music, esp. through say the Amp’s line in, then that won’t be easily done. 

If as jgatie says, you’re happy to use the system with the Arc+Amp then streamed music will play across all speakers. However the Amp line in will be disabled. 

If you want surround music, which you may get through say a Blu-ray player attached to the TV, that would only work with the TV on…

@Ian_S 

After talking with some guys, we came up with the following idea to have surround sound musics without TV. I think you can play the music in iPhone/iTune and stream it to the ARC. 


What do you think?

AirPlay 2 to any Sonos device is stereo, and does not contain surround channels. In order to get surround into the Arc, it requires something coming in on the ARC channel (usually a TV set generating this) to the Arc, via HDMI.

Thanks @Airgetlam 

One more question, with regarding to the two in-ceiling speakers above, I am weighing in on Bowers & Wilkins - CI600 Series 6" In-Ceiling Speakers rather than Sonance - VX66R - Visual Experience Series 6" Medium Round 2-Way Speakers (Pair) - Paintable White. Would you agree?

 

For some more information: my living room area is 24ft by 12 ft, and ceiling high is 7.5ft. The setup is in the middle of the room with the couch facing the long wall where the TV is located right in the center closer to the ceiling. I think two surround speakers like above are sufficient and I don't need 4 (I think).

 

I am almost ready to purchase...
