Meet Arc, Brilliant sound for your TV

Extraordinary sound meets elegant design

Eleven high-performance drivers, including custom elliptical woofers and precisely angled side tweeters, produce vivid detail and impressive bass for home cinema and music streaming. Arc's upward-firing drivers create a multi-dimensional soundstage that moves around you, rendering every whisper and explosion with dramatic clarity, detail, and depth.

With its elongated shape, soft profile, and seamless façade, Arc discreetly mounts to the wall or sits beneath the TV without pulling focus. When mounted, a magnetic sensor detects the orientation and smartly adjusts the EQ to temper bass resonance.

Arc’s sound was specially tuned with the help of Oscar-winning sound engineers to emphasize the human voice so you can always follow the story. The advanced processing creates five phased-array channels that masterfully deliver sound to your ears from all directions at the exact right moment. Use enhanced Trueplay tuning technology to optimize the sound for the unique acoustics of your room, even calibrating the height channels for precise localization.

I’d suggest there’s no advantage to having the Sonos Five as surrounds versus the Sonos Ones.

I agree. The Sonos 5 are more for bookshelf speakers when you want to listen to music. The Sonos 1 make perfect surrounds, Sonos 5 would be too overwhelming. You don’t want to emphasize the surrounds too much.

Ok, so I've read every comment on this topic and thought I had it straight in my head as to how my system would work if I ordered an arc, but a call to the Sonos sales team has left me confused again.

I've got a 2016 LG TV that has 1 HDMI Arc socket. I've looked in the sound settings on the tv and it shows Digital Plus compatibility which from reading some of the posts here I understand to mean that I'd be able to get compressed Dolby Atmos, however the Sonos sales guy said that this wasn't necessarily the case and that my TV would also need to be able to decode the Atmos signal (he mentioned codecs but didn't go in to detail).......is this right?

Dolby Digital Plus is the compressed codec that among other content can carry Dolby Atmos. Your TV needs to be able to pass Dolby Atmos through, and your sources need to be sending Dolby Atmos as well. Even if you don't have Atmos coming in, you’ll still probably get Dolby Digital Plus, which sounds great. As to if you'll get Atmos, that depends more on the TV and the sources. And not everything has Atmos either. For example, the HD Netflix service has some things in with Atmos, and lots without.

Regarding the eARC/projector/splitter discussion - forgive me for not having read past page 5…

HDFury vertex2 has the following in it’s description:

Vertex² now support ARC and eARC sound extraction from TV for up to Atmos high bit rate over TrueHD forwarded to any AVR input via Vertex² HDMI audio output

It does read more as though it’s about unpacking an eARC datastream into a different format, rather than packing an audio stream into eARC.
Catering for the case where an AVR doesn’t support eARC but a TV does. This honestly seems like a more useful choice given I assume most receivers would support direct audio streams _in addition to_ eARC.

eARC (for up to Atmos High Bit Rate over True HD) is possible when eARC TV is connected at Vertex² HDMI video output, extracted sounds from TV APPS will be output from Diva HDMI audio output that can feed any AVR input.

That does suggest that the device is actually doing an eARC discovery and protocol negotiation, or the TV wouldn’t be _sending_ any audio stream to capture. Unfortunately I couldn’t easily find whether eARC is a symmetric protocol, so no idea if it should be able to play as the other side of that connection when forwarding..

That said I’m hopeful, given how versatile their products are and the fact they use FPGAs rather than ASICs. I’ve asked their support whether it’s a viable use case and if not will enquire about potential firmware updates.

Can Sonos look into the same? I’m really hoping that it’s possible in firmware to determine that it’s not an eARC signal and try treating it directly as an Atmos stream. Or allow that configuration from the user via the S2 app.

I’ve got a vertex on the way because it honestly seemed like a cool piece of kit to have for those times when I just cannot get hdmi devices to talk to one another, so I’ll be able to provide an answer in a little over a month. If it doesn’t work, then I guess I have a very expensive asthetic upgrade to the playbar and will be listening to Dolby Digital for a while.

(I found this doc useful for a high level overview of eARC implementation details)

Update - found a response from HDfury in avsforum that notes it will not do what we need:

So there is not one product, AVR or other that can solve this for us?

This might not be the best place to ask, but i have only one shot at this and want to do it right.

Invested deep into Sonos products, i waited for a Playbar replacement for a long time. When Arc was released, i ordered it straight away, together with a wall mount. However… I am kind of stuggling here if i actually need a mount, or if it would actually be better without.

Let me explain my situation:

I recently replaced my LG 65E6 with a 65C9 OLED and i’m about to wall mount it. The ideal mount height for the middle part of the TV is at eye level, for me that would be around the 105cm (41 inch) mark. The cabinet that is going to be under the TV will be 42cm (16.5 inch) in height. That leaves me approximately with 21.5cm (8.5 inch) of space between the bottom of the TV and the top of the cabinet. Knowing that the height of the Arc is 8.7cm, i will only have about 13cm (5.1 inch) to play with.

Do i:

Wall mount the Arc, about 10cm underneat the bottom of the TV and let it ‘hover’ over the cabinet? I’m not sure its worth it, but at least the sound wont deflect of the top of the cabinet as much, as the bar hangs ‘free’ and all cables will be hidden behind the wall.
Put the Arc on the cabinet, all though i would not like it to be put right at the front edge because of cables being shown. But this would result in deflecting from the top of the cabinet? And isnt the Arc seating too low at 42 cm?
Mount the TV heigher to create more room for the bar to be mounted, all though this would mean that the TV isnt on the ideal height…

What would you guys do?

and @Ryan S what would technicaly (looking at the Arc) be the best thing to do?

I would keep the TV at the right level as IMO this is much more important than the height of the sound bar.

I would put the Arc on top of the cabinet. Move it around front to back on the cabinet to see if it makes any difference to the sound (please post back if you notice big differences), find the best spot and enjoy.

Thanks for your input.

I am kind of leaning towards this one also at this moment, does TruePlay factor in deflections and so on?

Airgetlam

I’m sure it will, otherwise there wouldn’t be much point of TruePlay. But then again, there can only be ’so much’ adjustment, not infinite, so I wouldn’t expect miracles. Basically as much change as it can currently do.

Although it’s not the Arc, I’ve actually both the setups with the Beam...hovering between TV and cabinet and placing on the cabinet near the back. I think both options look good and both sound good...but again Beam and Arc are not the same. Obviously, placing on the cabinet is the easiest option.

The one thing I’d say that most places, it’s technically not with local code to have power cables behind the wall that are made for that purpose. I opted to use a race way rather than building a 2nd outlet just for the Beam or having wires exposed.
