Yeah I’m afraid I don’t have that much sway, ​@Gavalar

Hi ​@Gavalar 

I’m an Arc Ultra owner myself, and have been hoping for the same too!

Made me giggle! I am surprised you have not been pushing it harder your side!

 

Can this be escalated as it really is killing sales, especially as the company is still on relatively thin ice and I was hoping Sonos would listen to customers more now? (Not you personally, but the company in general). 

 

Many thanks 

Exactly the reason I have not “upgraded” to the Arc Ultra, and won’t, until they provide the ability to adjust the center-channel, discretely. I guess Sonos just hates money?!

I think this is the problem. Sonos management doesn’t appear to want to listen to its customers, or its staff :-(

They listen but it seems the number of complaints, ones called into support, less so forum posts, drives the fix priority list.

Hey ​@Stanley_4, appreciate the message. I and several others contacted Sonos directly, raised complaints. I even emailed the old CEO.

Nothing ever done about it. If I’m honest. I’m waiting for something decent to come on the market that is a rival. A shame as this would be close to what I need with adjustable front left and right.

 

Hopefully the ProTune will sort.

Hi ​@Gavalar 

At this point, the audio team has moved onto other products, so I would not expect this to be addressed - at least on the Arc Ultra product level.

However, as we have recently introduced ProTune with Amp Multi, it is distinctly possible that solutions will come in time that will allow individual users to control things at a level sufficient to address this criticism.

Please also be aware that the perceived boost given to the centre channel on Arc Ultra only exists at lower volume levels - above volume 60%, it does not exist.

I hope this helps.

It is not a “perceived” boost. It is objectively measurable that the left/right are half the volume of the centre  

And putting the volume to more than 60% does not change anything … the centre is still 6 db higher.

I meant “perceived” as in it can be perceived, not as in it only exists in your perception.

And putting the volume to more than 60% does not change anything … the centre is still 6 db higher. 

I am only going by what I have been told by the people that designed the product - I have not tested it myself.

It appears the centre is boosted slightly a lower volumes.

I agree the left and right channels are significantly quieter regardless. It’s not good Sonos has let this slide for 18 months.

 

Hopefully someone that has suitable authority at Sonos, to promote change within the company, will read this and have the issue looked into and rectified.

Unless its reflected in their sales or stock price, its not important enough for them. “Professional” reviewers have by and large ignored the problem (or their methodology so lax they didn’t catch it) so it doesn’t get any attention. I challenged ratings.com to look into it and they regurgitated what Sonos had said about it (the magic of Sonos mixing all the sounds doesn’t map to traditional L/R blah blah blah).

I missed my return window and couldn't get the resale value I needed, so I kept my system. Very depressing. I ended up adding Front L/R with sequencer and just try to ignore the channel imbalances (L/R now too loud in some situations).

I am holding out hope they’ll enhance user configurable settings to allow us to adjust ourselves as well as allow feature to properly add and mix in dedicated L/R speakers with TruePlay.

On the other hand, its possible this is a hardware design issue and they just can’t fix it.

Regardless, I’m not a Sonos fan, this has left a sour taste and I tell all my friends. When I’m ready for an upgrade in a few years, I will shop accordingly. In the meanwhile, I’ll keep coming back here to post for passersby how disappointed I am with my $5,000 full boat Sonos system. I feel I got a defective product, the company investigated and basically says “too bad”, so I would not recommend.

Shop other brands.
