Sonos ARC- still muddy Bass

Hi,

I just heard a very bass-heavy song and unfortunately I heard a problem, with very deep bass it sounds like the drivers are at their limit and it sounds like an unclean muddy vibration... No matter if with trueplay or without  , trueplay made it even worse ... With the subwoofer you don't notice this problem.

 With the stereo distribution, one does not always have the impression that something comes from the left or right and with Atmos from the top only minimally.

 The voices sound rather thin and artificial and the adaptation to a 5.1.2 system with the Sub and 2 Play 5 does not work properly either, because the speakers sound very different in tone and you think that it is a completely different system from a different manufacturer  is.

I have a sub, the Arc in front of the TV on the furniture and 2 Play 5 in the back ... Everything at 0 EQ and still the Play 5 sound much warmer and more powerful than the Arc.

 The bass reproduction is not the problem with the Sub, rather the coordination of the Arc with the Play 5.

 With the Arc alone, the bass distorts at a volume of 50% and the bass to 0.

 The best way to notice that distort on Spotify with the song hypnotized by Oliver Kolletzki as well as the bad tuning, also in Atmos films via Netflix where cars drive ... They sound much more real and pleasant on the Play 5 than on the Arc.

 Trueplay was measured with the iPad Air 2, but the bass problem also exists without, just a little less.

 I'm going to make a diagnosis after work tonight.

 I have the feeling that the soundbar is not yet fully developed and has come onto the market too early.

 Does anyone else have such problems?
