First things first. This is not a rant. This is an expalation of a problem, which reduces the experience in 3D audio a lot. For background: I'm a sound engineer and music producer and I don't wanna sound arrogant, but I know what I'm talking about. (I'm a really nice and funny guy :D)

So lets get to the problem then :D

NO I'M NOT TALKING ABOUT THE FRONT FACING DRIVER

for better understanding watch this VIDEO

This bug appeared the moment I switched the Arc with the Arc Ultra. Before I made the switch I was on the 16.1 app and firmware. So I don't know if the Ultra causes the problem or the app/firmware. Before the switch everything was running as it should.

So, since there is not much of a topic around this, I'm curious if I am still one of a few who have this bug or one of a few who noticed it.

I made this post in Reddit, but not everyone is on Reddit and the more people know, the faster Sonos can work on it. Reddit discussion

I didn't saw any review which mentioned it.
As you can see in the video, the rear driver is completly silenent when the Era 300's are paired with the Arc Ultra. Also Truplay isn't "sweeping" the driver either. (Timestamp 0:44)
So the mesurement isn't right.
First I thought it could be a feature instead of a bug, but it doens't fit the Dolby Atmos recommendations like this. You won't get sound from "behind" your seating position.
And I remember Sonos self promoted it how it should work, where the rear driver is playing.
 

DOLBY ATMOS LAYOUT

Sound from side driver/channel should boucing off your side walls, rear driver/channel bouncing off the back wall of your seating position and height channel obviosly bouncing off your ceiling. Thats why you should position them facing forward. At the moment you don't get the immersion that sound is coming from behind you, since the driver is silent.

I tested every setting, played the Dolby Atmos testfile (MKV KTrueHD Atmos] and MP4 PEAC3 + joc Atmos]) from different sources (TV Plex app, Nvidia Shield, from a USB through TV) Same result everytime.

If someone could test this behavior and can confirm this, it would be very nice. Sonos can't fix something they don't know and if most people doens't recognize doens't mean something isn't wrong.

Currently I'm running app version 80.12.04 (Android) and 80.12.03 (iPhone) and firmware version 81.1-58210.
If you don't have this problem, what version are you running?

And last but not least: IF this ever getting fixed, the experience with Arc Ultra and Era 300 will be much better! I love my Sonos products soundwise and Arc Ultra is sounding really good, but it could be much better.

Have a nice day

Taking the video down or making it private shows clearly that we are right. Did someone downloaded the video before? 😂

What a s***show, sorry.

I guess we won't get an answer on that.

But to be clear, I don't think that Corry, Jamie and Keith are lying in that case, cause they just telling us what someone told them. Its coming straight from the level 3 audio team. Corry, Jamie, Keith and the german support guy are just "support" and they got informations from "above".

The thought of downloading the video came to my mind yesterday, but I thought Sonos wouldn’t do that because it will look even worse for them if they took it down. Well, they continue to surprise me!

Well, as “official” spokespersons for Sonos I guess they would at least have a clue of what’s really happening here. I realize it’s their job and they’ve probably been told to lie and that’s what they have to do, but this whole thing has become really shady, even for Sonos standards.

 

Can’t believe we’ve come to this, I regret giving € 2.500 of my hard earned money to such a despicable company


They took down the video?!

@tomwarren , I believe this just became newsworthy.

There is clearly a disconnect in Sonos between the Product Managers and the Product Marketers. I suspect the latter are working with the specifications of the final product as opposed to what will make the actual launch. This is a common problem with software based appliances which is why the golden rule is:

Never buy a product for a promised feature (you really want) that is not yet available.

It always pays to wait until the dust has settled so you can clearly see the product and not the promise.

Remember 2 things about early bird offers:

  1. They benefit the seller more than the buyer
  2. The discount is always matched, and some times exceeded, later in the sales cycle

Sorry Jamie, the last part (The Era 300 plays rear channel audio through its height array.) is such a BS reply.

Here’s a Sonos Era 300 Q&A YouTube video from last year: 

 

Pay attention to Product Manager Ryan Moore’s answer to the very first question. The rear channel audio is SUPPOSED to be playing from the other inward-firing side tweeter/woofer. What we have now is clearly a bug that’s being dismissed as a “feature”.

Thank you! And saying it wasn't like that (this is what the audio team said) is just a lie.

im at a standstill to return the system or not………...

Return it while you can… it's too late for me. I regret giving Sonos time to solve it, now it seems they are telling the issue is “as designed”.


I feel robbed now, if only the outside woofer and tweeter along with the upward firing tweeter are working in surround mode, how much different are these Era 300’s in surround mode than if I just faced my old One sl’s facing the wall, absolute farce...


I am not familiar with this environment - is there any online place where we could make more noise about it, so other the message reaches a wider audience?

Why would a new SONOS Arc Ultra owner want to add 300’s to a system as rears when woofers and tweeters are being shut off? Waste of space and money, give us a purpose build surround speaker not extra woofers and tweeters we will never use. I understood shutting off the front facing tweeter for  but this new behavior does not make any sense.


The sooner they come back to the office, the better

I don't know. Maybe some YouTube reviewer?

If Sonos just said: "Yes its a bug and we fix it" it would be not that bad as it now is. Telling it was always like that, trying to delete their old statements and stuff is so suspect. AND telling it would sound better like it is now is just not right for every room and doens't fit the Dolby Atmos specification either. I used my old system (Arc, Era 300 and dual sub) within a day when I made the switch to my new system (Arc Ultra, Era 300 and dual Sub) and I noticed it immediately in a bad way. Yes the Ultra sounds much better but the Era 300 sounds much worse.

Most people saying: "My system sounds good". Sure it does, but it could be much MUCH better and more precise and detailed.

Again: IT WAS LIKE THIS! Even if Sonos deny it. I am a sound engineer and know what I'm talking about!

Why Sonos holding performance back and giving weird lying statements? Come on.…

 


That would need to be an independent reviewer. Most of them are incentivized by the manufacturer. I think...

I wouldn't say that tbh.


Sooo…..something is quite clearly not working as it’s supposed to and maybe it’s too much of a headache to fix so…..let’s just say it’s meant to be like that and leave it as it is?


Going to be great when in the future the audio plays exclusively from the top driver only and Sonos tells us that it’s all by design and it’s the way things are meant to be on a £750 pair of speakers that have 4 directional drivers.

Peter Pee on YouTube might be a good reviewer to raise the issue with. He seems to call out SONOS when things don’t work properly. As a sound engineer and Arc ultra owner considering the 300’s I’m definitely interested in SONOS continued response to this issue and their Atmos / Surround implementation.

Yes true, he came into my mind first. I hoped he would talk about this in his last video.

I'll comment on his next video for sure as early as I can. Maybe some more from here do it and get his attention.

I tried in different videos, never answered


There is no audible output from inner woofers when Era 300 is bonded as rear surrounds.
This is by design. The rear speakers are designed to disperse sound throughout the room, rather than directing it to the listener exclusively. 

The Era 300 plays rear channel audio through its height array.
This, too, is by design. The Era 300’s DSP (Digital Signal Processing) leverages either the rear height tweeter OR the outward-facing tweeter/woofer to create the intended sound experience. Because of this, when you play the Dolby test track, you might notice that rear height channel as being active during rear-channel playback. This is expected.

 

Starting at 05:37 the video goes into detail over the inward facing drivers, so there has definitely been a change to the rear-channel output compared to what it is now.

 


I don't understand how they came to this conclusion. A couple of days ago a sonos employee posted on here saying that sonos were aware of the issue and investigating, if this was normal behavior then they're should be nothing to investigate


They probably realized they’re too damn incompetent to Fix the mess they made so they decided to play a joke on the customers that are paying for their salaries


When something isn’t working, users themselves are quick to notice it.

That’s what happened last year when the Era 300 launched. Users noticed that the front driver (and only the front driver) wasn’t firing when they are used as surrounds. Sonos then gave an explanation that made sense: the other three tweeters represent/reproduce distinct channels in a 7.x.4 setup (side surround, rear surround, height surround) while the center driver have nothing to represent/reproduce.

Fast forward to the Q3-Q4 2024. Users are noticing another tweeter of the Era 300 that used to work isn’t working. It’s obviously a bug, given the fact that it used to work as per Sonos’ own explanation from 2023. There’s definitely something fishy going on when all of the sudden, the bug is being explained away by statements that made zero sense, that contradicted their own statements and users’ experience from the year prior. Making the evidence (Sonos Era 300 launch Q&A YouTube video) private makes them even more suspicious.


I just hope they fix it.  They are probably trying to do some damage control and trying not to alarm the majority of people with the plan to fix it at some point.  That is my hope at least.

Spot on summary. I really hope they are fixing it someday. Probably selling it as a new feature then haha
