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

63 replies
9245 views

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.

I have an ultra (before arc) and sub gen 3, bass seems fine but not gave it a good work out yet, though I haven't attempted Trueplay as this seems to be where people are noticing the issue once done.

Sonos really need to issue some update on here.

I want to trueplay my new ultra, but this potential issue is holding me back!

Why wait? If you don’t like the sound with Trueplay, simply disable it, or reconfigure the room and the previous Trueplay setting will be removed.

Yeah, but i’ve seen some posts that to get the bass back they have had to reset their speakers. Im happy to wait a while to see if Sonos release a fix.

Maybe Peter Pee will give us a before / after TruePlay frequency test. Then we can visually see what’s going on.

Maybe someone in this community could do the same.

Maybe Sonos could do the same.

Now it looks like Sonos only tested arc ultra with sub gen4. I have gen 3 sub and with arc ultra it sounds worse than beam. At this point i am going to return ultra and wait till all the major issues are fixed.

I have a feeling there is either a bug with the Ultra and subs….. I actually don’t know if TruePlay is really making that much of a difference, besides allowing the bug to be more noticeable after the Ultra has been tuned.

OR, the built in Sound Motion sub on the Ultra is just holding onto to much of the bass from the LFE channel, and the crossover is set incorrectly when paired with some or all subs… the Arc and Beam seem to pass all the bass to the sub woofer once once is paired, the Ultra doesn’t seem to be doing that, as you can hear the bass still coming out of the sound motion sub in the middle of the Ultra, even when it’s paired with all or specific solo sub, and dual sub combinations.

again, anyone from Sonos want to acknowledge a possible bug with the Ultra? And if so, how should we report it or provide you more data around the possible bug?

Yes! This! This is exactly what I was thinking. I can hear the ultra handling sounds that would have been handled by the subs with the arc and it just sounds flimsy! I figured it has something to do with the sound motion woofers. All I know is, I want my bass back!

I am having the same issue. I just upgraded to the arc ultra to replace my gen 2 beam. I have a gen 3 sub and 2 one SL surrounds. The bass from the sub is minimal now compared to what it was before, also what I have noticed is the white lights on sub and the 2 ones are no longer lit and they actually look like they aren’t switched on (ones are as I can hear them fine)

The white status light led is disabled by default. If you want it to show, then enable it in the app.

That's what I think too, I have the same feeling but I'm waiting for Sonos to confirm it (I hope they will have time to look into this issue soon).

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.

Hi @Corry P

Thank you for taking the time to answer and for the proper consideration of the problem ; but just to be absolutely clear : the problem is not the lack of bass of the Arc ultra itself, but the overall lack of bass WITH a Sub Gen 3 type (and especialy compared than before with a Beam Gen2 for exemple).

Hope you’ll find the source of this malfunction and provide an update when possible. Thanks again and please keep us informed here if possible.
