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.

@Ryan S  Thoughts? I haven’t ordered the sub, would be disappointed if this happens to the bass

Same issue here. Have a sub so didn’t notice yesterday. Disconnected the sub today to test the arc solo and bass is bad. Especially with music. So sad.

I agree I am disappointed with the arc as a music speaker.  The play 5 2nd gen that was standing in the same place as the arc is now is a much better music speaker.  

The bass without the sub is terrible at anything but low sound levels

I was hoping to not have to rely on a sub for bass given I’m in an apartment and do not want to not annoy the neighbors.

If this happens to me, it’s gonna be back in the box real quick. $799 after all.

@ftm, how would the Arc be as a music speaker if this problem with the Arc’s bass wasn’t there? Did you try it at lower volumes with music? Thanks!

At low volume it sounds no better than the beam it replaced. Just a wider sound stage.

Why none of the reviews mentioned this? It’s like they were paid to say good things. Mine arrives on 12th. Let’s see how it goes.

Hi everyone, we’d love to look into this more, but we’ll need some more details to look into it better. Have you noticed this sort of sound from all sources of audio or just music? If it’s just music, does that mean all music services you’ve tried, or certain ones?

Does it sound better with Trueplay turned off?

How is the Arc set up currently? Do you have it open on a table, wall mounted, is there a surface above it? The more details, the better.

Thanks! We’ll try and get to the bottom of this together.
