Sonos Arc - Metallic Sound

Hi All.

It’s a relief that Sonos has identified the bug that’s causing the bass distortion in Sonos Arc. Thank you @Ryan S for working with the Sonos Communty to identify the problem quickly.

Having said this, I believe that Sonos still needs more work to make the Arc sound as it was advertised. Currently, multiple people on Reddit including myself are reporting the highs being too high which sort of feels “harsh”. This improve the speech clarity and brings out details in the movies, but the warmth in speech is lost because the voices sound thin and metallic (for eg. actors I know having heavy voices don’t sound heavy). I was expecting the mid-range to be a lot better considering the Arc has 8 woofers. 

I have tried TruPlaying twice without success (Turning TruPlay off produces muffled sound). Adjusting the treble also did not help much. Loudness turned on and off does not make a big difference either. May be, this is how the Arc is tuned?!

 Anyone else feels that Arc is over-emphasizing the highs with compromised mids?

Hello everyone. I’m a product manager at Sonos. Thank you for sharing your experiences with Arc. The development team is monitoring this community and listening to your feedback. 

As we do with all Sonos products, we’ll continue to improve the experience for Arc through numerous software updates into the future. Last week we issued our first update (12.0.1) to fix a bug some customers were experiencing with low-frequency distortion at higher volumes.

I see that the forum is very stopped, many have already returned everything and I think that others who have not yet done so and continue to have after seeing the technical support that is in this forum have realized that it is useless to write your problems here . There are people who have real problems ... it is not a matter of taste. Whoever believes it, go to the muddy bass forum and see the video they have uploaded, comparing a song with their playbar and with arc sonos ... it's not a matter of taste. It bothers me to hear the bright highs and the ssss so emphasized. But hey, when we return it to those who are missing, the problem ends for everyone. Sorry I thought I had an automatic corrector.

I agree, become very quiet.  Maybe some sent back and bought other brands or maybe bought Arc again and were satisfied then.  I'm waiting for my Arc after being sent back.

There’s a new batch coming into my local shop on the 14th.l am going to check it out in the shop.

I honestly think it’s mostly a trueplay issue (and not a hardware issue). Something is wonky with trueplay. After what feels like 5000 trueplay attempts, I have done the magical one where the sound is pleasant. However, I am now afraid to move any speakers lest I need to run trueplay again. 
 

Additionally I find that the AGC (automatic gain control) on it may be a little aggressive at times. That is, some times a character would speak at a perceived lower volume. This is not a cut out, as the same occurs when playing back on a different device. However, with the Arc, the difference is very sharp.

What was your magical TruePlay attempt?

Without any Trueplay (like it has to be for all of the non iOS owners, how does it sound?

Trueplay should refine the sound and tune it to the surroundings - not be a requirement and sound as bad as it does out of the box.

This is not quite right. Any “high-end” soundbar or even home theater system has room correction features. This is borderline required for these soundbars because theres so much the room can affect the audio you hear. There is no way to tune a soundbar for every room space, echo etc. You also cannot adjust the soundbar speaker setup, you cant move your side channels or center channels like you would with a home theater setup. So “processing” is all they can do to make the sound work in your setup. Also trueplay is used to calibrate surround speakers and atmos height speaker performance (Arc).

 

If you ask without trueplay, then go for a cheaper soundbar without these “high end” features. The criticism here is that you need iOS to do it. I understand why it sucks for android users and why SONOS does it. But honestly if youre going to get a sonos surround setup ($2k or even sonos soundbar with surround speakers you need to do truplay for best performance. Don't settle for non-truplay you went and spent all the dough so try to borrow an iphone for a bit at least. You only need to do this once(maybe a couple of times) 

But buying sonos and not using truplay is plain silly, because thats one of their strenghts the processing and audio adjustment for the room. Thats what soundbars with surround setup need to be able to produce better than expected sound for the soundbar design. 

Literally the arc does audio processing to make sound bounce around your room walls (including ceiling)… if you dont truplay it just wont be optimal.

Sonos released new version of iOS app today. 12.0.4. Did somebody try the truplay dance with it? Solved it this sound problem?

Looks like it is an “App only” update, my speakers seem to still be on 12.0.3 after updating the App

I would expect that Trueplay changes/updates don’t necessarily require a speaker firmware update. Pretty sure the app does all the EQ calculations locally and just sends an updated profile to the speakers, so if the changes are just in how those calculations are made, it would only need the app to be updated.
