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.

Penetrator at 50% volume. True play on and bass at zero. Recorded from 1m away on an ipad pro. Songs without vocals help nail the issue because the sound can get lost in the vocals.

Damn, that sounds even worse than mine, or your phones mic is much better. I was like 10 centimeters away.

It’s harder to hear when mixed in with vocals, so I chose a song without them. recorded with an ipad pro

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

Although there may not be the same issue when paired with the sub, I am noticing that the sub does not hit anywhere close to where it was when paired with the Beam.  I do have TruePlay tuned, and it is soft when I turn this off as well.  

Interestingly enough, I just commented to my wife the other day how nice the bass sounded when we were listening to music.  Now that it is paired with the Arc, it is disappointing that it is not as strong.

I’ll just throw this out there for consideration.  If this problem does turn out to be hardware and not fixable via software, returning the Arc is certainly one option.  However, I might be willing to accept buying a Sub to address the issue as long as a very steep discount is provided.  I realize that this will not be acceptable to folks who don’t want a Sub for various reasons.
