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.

Is there any way that anyone can share a recording of what this sounds like, somehow?

Clarification please.  Does this problem go away if a sub is included because the problematic frequencies are directed to the sub?

Yes there is no issue when paired with the sub

I do also notice the bass isn’t as tight and seems muddy, I was wondering why I wasn’t super impressed when I first listened to my ARC, given all the positive reviews. It is definitely is the bass that is holding it back. Hope they sort this out soon.

Can you guys post some more media files if possible? This will help @Ryan S some more to communicate with the engineers.

This is the trailer I played for my first test.  The first ‘boom’ when Paramount shows up (6-7 seconds) my Arc immediately gives that bottoming out sound.  Throughout the trailer it continues to do it as well.

(It used the ac3 audio and showed 5.1 Dolby Digital in the Sonos app.)

Other trailers I tested were found here:

I tested the DD+ Atmos ones as I don’t have eArc.
