Sonos Arc Muddy/Bottoming out Bass

Beyond thrilled to receive the new Sonos Arc. True played my room and I have loudness on as well connected to LG B8 using Tidal and Spotify. Most of the sound range is phenomenal, aside from the bass. At even half volume the woofers are extremely muddy and sound terrible. Not sure if this is because I have under two hours of use but I wasn’t expecting to have to break-in the speaker. I own set of speakers next to it in the same room (KEF LS50W) and the difference is night and day. There have also been posts on Reddit regarding this issue. It is interesting given no reviewers have mentioned this issue but more than a few recipients have. Has anyone else experienced similar issues? Turning loudness off helps but it is disappointing for such a highly anticipated product.

Just curious how do you tell the build date? I’m sure it’s in this thread somewhere but at 45 pages....

It’s the four digits either at the beginning of the serial no or end depending on the device

I would be skeptical of ones before June 10th otherwise you assume that they noticed a problem prior and still sent it out. Also, to the person who mentions Peter pee video above he also says in the next video released that to be in the sweet spot to experience atmos with 9’ ceilings that you should be 3-3.5’ away so if you need to put against the wall then you need to use wall mount with no way to angle the arc. Based on his review if you don’t mount it to the wall and put it on a shelf of some sort then you should place it toward the forward edge of the listening position. But all this is based on a guess of what angle the speakers are actually mounted at. Cluster f...

I just received my 2nd Arc. First one was purchased through Bestbuy. I was having the same problems everyone was having in this thread. Decided to return it and re-purchase it through Sonos. Waited a month and finally received it today. All the problems i was having previously is gone, the new one sounds good, i purposely set the bass to 10 to test it out and it doesn’t bottom out anymore. So it’s definitely the arc itself and not software. For everyone that’s having problems with theirs, just return it and re-purchase it again.

Build version on your new? Happy for a answer

Hey guys, also check to make sure your night mode is not automatically turned on. Somehow on my unit, it was automatically turned on and it also affected my music playback. I though it sounded like crap unit yesterday I went in the app and found out night mode was On… when I turned it off, everything sounded much fuller on tv and on music playback.

 

It’s most definitely a bug since when activating night mode in tv, and the listening to music, it shouldn’t carry over, but it was “stuck” in night mode on all sources.

 

could this be the metallic sounding arc people were reporting?
