Sonos Arc wall mount: How to fit outlet and low-voltage behind the mount?

I don’t have an answer for you, but I’m eager to see responses from others. I’ll be doing a similar install next month.

I called Sonos Support, but they didn't even understand the question, they were clueless.

This is turning out to be a huge, code compliant, problem. 
An Arc investment, especially with the extra outlay for the wall mount, and the slick photography of wall mounted Arcs, is not compatible with an electrical outlet behind the mount, especially with little space and a six foot power cord.

Really frustrating. Running the cord behind the wall for three or four inches, a spur, then using the outlet behind the TV would make things a breeze. Code, however :(
 

I’m hoping that folks have a solution for this new product. So easy with the Playbar—just place directly under the TV. No can do with the Arc and it’s two upward-firing Atmos drivers.

Awaiting any suggestions eagerly. Thx 

I am sure I can engineer a solution to make this code-compliant in NYC/Chicago but it would require extensive drywall work to build a soffit, which in turn requires more wall depth not always available. And it would limit the application to new construction and full remodels only.

I spoke to many industry peers and they are amazed how the ARC wall mount design excluded NYC/Chicago (two large markets) from compliance. Leniency is becoming the norm in the US.

But what amazes me the most is that Sonos is not even responding to my inquiries much less to this thread. 

@btoursonos, wouldn’t a Hubbell “JLOAD” RJ600 do the trick?  That’s if I understand your problem to be mounting (hiding) a single duplex outlet sideways with a split high/low voltage divider & metallic connectors:

(By the way (not that you asked!-), depending on the depth of your TV mount, you might want to offset the Sonos Arc from the wall or else move it vertically farther away from the TV.  Even with the forward angle of the upward-firing drivers, at only 2” away it must reflect off the TV before it gets to the ceiling.  Of course at only 6” below, the reflections from the main front-firing speakers off the dresser are a problem too!  To me, Arc is not a good Master Bedroom solution with typical close-quarters.  If this isn’t an MBR, then consider allowing more “breathing room” in your TV living area, so the sound doesn’t get “muddy” by accident.)

@tracker Thank you for the recommendations on the clearance, I hear you, but the Interior Designer is forcing me to a 2" clearance (but at the end of the day I will extend it to 4" ;-)

The Hubbell solution you sent is not compliant with NYC/Chicago code, we need to split line and low voltage in two separate wallboxes - or - we need a 2-gang wallbox with metal separators. Welcome to NY!

I would love to see Sonos comment on this important topic...

Wait, AHJ **prescribes** a 2-gang wallbox?  Usually code language is more general than that...  So “merely” a metal separator, including 100% enclosure of the wiring (due to the integrated plug design) isn’t enough?  [Edit: The Hubbell sheet *says* divider included with the plug, which would mean it isn’t permanently welded-in, but photo #1 on their website *shows* the box with a metal divider, not the plugs with plastic inserts.  But photo #2 shows a *different* box construction, a sliding insert, thicker i.e. plastic!  So I’d at least buy one, to see if the divider was pre-built-in, unless you already know it has specifically been rejected.]  Inspector-says vs. actual language, love to see the quote…  If a 2-gang wallbox is required then you’re hosed no matter what, because you can’t hide it.  Just screw the TV bracket vertical adjusters down after mounting, as close as possible to the soundbar and the AC cord on the surface of the wall should be invisible up to the TV box.

Designer?  Give up on the sound -- it’s as close to the TV for that integrated look as possible.  Even a B&O “Stage” -- very designer-friendly! -- although it’s thicker so it avoids the TV offset, plus angled speakers are in the field so it does not have drivers on the upper edge, nevertheless recommends a greater distance between it and the TV.  Their solution to reflecting off the horizontal surface below is to just sit it on top of the dresser (with 90-degree re-purposed and eq-ed drivers).  Enh.

Yes, @Sonos still needs to address the issue, at the very least to provide a 3” AC cable in the box with that bracket!

My installer came today. Did a great job. Almost done.

First, the speaker must be at least 3” below the TV if wall mounted. Mine’s 3.5 and the difference with another 1.5 inches is pretty incredible. If you can manage 4 to 6, even better.

Coming Thursday to put the electrical box behind. He thinks he can organize the extra wire from the long cable to make it invisible, but if I can get a short one, even better.

Anybody know the correct model of connector needed? 
 

Here’s the Arc power cable. 
 

3.5” made all the difference, FYI.
