Arc Ultra + Sub Gen 3 : Sub less powerful than before !?

Hi,

I just replaced my Beam (Gen 2) by a Sonos Arc Ultra, in my home theatre system.

But now, the Sub Gen 3 seems to be a lot less powerful.

Before, with the Beam, when I pushed the Sub level adjustment to +2 or +3, i was able to balst the entire room… Now, even if I choose +8 on the Sub level adjustment, I feel it but very light. I can’t have the same “bass blast effect”.

Obviously, I completely reinstalled the system in the App and reseted each element of my home theatre system when I installed the Arc Ultra (included x2 Era 100 at the back).

Does anyone knows why this is happening (maybe someone at Sonos)...?

Thanks a lot.

    Hi @Matclane et al

    Thanks for reporting this issue.

    We are aware of an issue whereby, after TruePlay Tuning, Arc Ultra will either sound low in bass, or sound not quite “pristine”.

    To remedy this while we investigate, please try retuning, either with the same method (Quick/Advanced) or with the other, if available to you.

    If this does not help, please try disabling TruePlay Tuning in the meantime, if that sounds better to you.

    We thank you for your patience while we investigate this matter.

    I hope this helps.

    Thank you for confirming the lack of base is a recognised problem. I have just received my Arc Ultra and connected to my existing Sub Gen 3 only to be massively disappointed with the level of base.

    Having just spent £1,000 on the Arc Ultra I hope Sonos address this issue quickly.

    DISAPPOINTED!!!

    Sold all my old gear ( Arc, Sub Gen 3 and pair of One SL’s) to a friend. For the Arc Ultra, Era300’s and sub gen 4. Thought this would be a small upgrade WAS I TERRIBLY WRONG!!

    DO NOT MAKE THIS MISTAKE!!

    I keep getting up to go over to the sub to see if it’s actually working. I’ve placed everything where the original gear was, TruePlay on or off and it SUCKS!

    Even my wife who could care less about this stuff was like, That sounds like $h!t.

    I’m now at the mercy of SONOS hoping there is a software upgrade and we all know that could be months if not years away.

    STRONGLY RECOMMEND YOU DON’T MAKE THIS SAME MISTAKE.

    Glad I found this form I thought it was just me.
