Wiring a SONOS surround sound system

@buzz how to “Add” Sonos Amplifier to sound bar? Wirelessly ?

Thanks.

Yes, both the rear amplifier for the surrounds, as well as the subwoofer in your drawing will connect to the Arc in the front via a 5Ghz (hidden) WiFi connection. As @buzz suggests, there should be a reason to connect the rear (surround) Amp with either an HDMI or Ethernet cable. 

Thanks, @Airgetlam  ! Would the following work?

We're currently remodeling the house, so I want to be 101% sure :) if any wires/cables need to be run, this is the perfect opportunity. I appreciate your feedback!

I’d think so, although I’d be semi concerned about two pairs of surround speakers. Not only is there the possibility that the Amp won’t be able to drive them both, but it will, from a surround standpoint, potentially muddy the soundstage for surround data. 

But I’m fairly particular, I suspect there are others who would suggest it’s fine. 
 

And on the flip side, there have been, although not recently in my memory, a lot of complaints about the ARC implementation on the Samsung Frame. I don’t know if that has been resolved by firmware updates from Samsung or not. It’s possible, given that I’ve not seen anything recently, but it’s also possible that it hasn’t. I don’t know, for sure. 

If you have the opportunity to wire, and you want rear and wide surrounds that actually do something different then Sonos is not your answer. You would be better driving the system from a more conventional AV amplifier with proper Atmos support with in wall speakers at the front too. 

Your diagram indicates that the electronics will be distributed at various locations. For best long term flexibility, I recommend installing enough wires that could allow all of the electronics to be housed at one location.

Placing SUB next to the couch is not optimal. It should be closer to the plane of the front speakers

I appreciate all feedbacks, I modified my system based on your feedbacks:

-- Yes I have freedom to choose any brand, and run any cable at this point. And in deed I will run spare cables just in case in the future I need to change out the brand. For now, I will stick with all SONOS products.

-- Move the two in-ceiling speakers in same plane with the Sub.

-- I will continue to purchase the Samsung Frame TV 75 in. I’ve found some feedback in other Sonos community thread but it looks like HDMI ARC works well with the Frame after some research.

Please let me know if you see any more issue, much appreciate your feedback!

Wire for left and right speakers in the front. There’s no need to pull them out now. They’ll be used at some point in the future.

I still don’t like the subwoofer location. Fortunately, it’s wireless and easy to move in the future if you agree.

@buzz all 4 in-wall speakers are wired to the Sonos Amp already. Agreed that the Sub is movable. Did I still miss anything?
