Hi ​@GleannanIolair 

Thanks for your post!

Sorry to hear of this bass issue you are having with your Arc setup.

I was going to explain the issue with comparing bass on a speaker with Loudness enabled as compared to one with Loudness disabled, but as you changed this prior to submitting the diagnostic, and tried both settings, it’s clearly not that.

Looking at the diagnostics, I only see one potential issue that might explain things - there is higher-than-liked error rate on the Sub’s radio input. Please ensure that it is playing along with the Arc 100% of the time by placing an ear close to it while playing. The Sub is not reporting interruptions, however, so this does not seem to be the issue. I am also seeing a single report of an ethernet cable being removed - although it does not currently look like the Sub is wired to ethernet, please don’t do so in the future, as it will only make matters worse.

It is possible that the Sub is in slightly the wrong place - you can experiment by moving it an inch/a few centimetres at a time until you find a spot where the bass becomes more prominent.

Another thing worth trying would be to bond the Sub with another speaker - if you experience the same issue with the Sub when it’s bonded to a different speaker than the Arc, it may have an issue - I recommend you get in touch with our technical support team, if this turns out to be the case.

I hope this helps.

Hi Corry,

Thanks for the reply. I tried a few things that didn't make much of a difference. I managed to get access on someone else's iPhone to truplay tune the room and it's sounding much better. Oddly on Android I can't enable/disable the truplay tuning now. I could before...is this missing on the new app? Also it seems rooms I'm almost sure I had truplay tuned quite a while ago have lost their tuning. Not sure how that happened.

As it stands I think the hardware is fine but I'm very suspicious of the software. Previously I remember the pre-tuned system sounding much better in the same room. Tuning was a bonus at that time that just gave everything a lift. Now the same system in the same room is hard to listen to. I've been a sound engineer for live bands in the past; I dont claim to be an expert but I know what I'm listening for, even if it is subjective.

I was thinking about adding a second sub to this room but I just don't think it's worth it based on this recent experience.

Has there ever been any discussions about adding a multi-band equaliser? Truplay is great but it's changing the system to what Sonos think is best (subjective), and there are all sorts of limiting factors like the phone mic state (possibly abused and not performing like new). I don't want to turn this into the iOS vs Android conversation regarding truplay (think we've had enough of that) but please just sort out a usb-c mic for the multitudes asking.

A multi‐band equaliser would at least give customers more control to make your excellent hardware perform the way they want it to. It would be great if you could see what truplay had changed and then tweak the sliders to suit individual preferences. At the minute it's all a bit take it or leave it which is disappointing.

Anyway, excuse what may seem like a rant, it's not meant to. I've loved owning Sonos speakers for nearly 15 years, but I feel like they're not as impressive as they could be. Investing some more time on software to improve the sound control/quality rather than the app look/feel would probably resonate with your customer base a lot more.

Thanks,

Stephen

Hi ​@GleannanIolair 

I am glad to hear it sounds better after TruePlay Tuning!

Yes - we are aware of an issue whereby Advanced TruePlay Tuning, once performed, cannot be deactivated or reactivated via an Android controller and we are investigating. We have no estimate for when a fix might be put in place.

If you remove Sub/Surrounds from a Home Theatre Primary device, TruePlay Tuning will be lost as the profile of the room changes.

TruePlay Tuning is a parametric equaliser, among other things. An EQ with more controls has been requested multiple times, so I can only presume that there were discussions about it, though I was not a part of them and cannot say how they went. There are still only two tone controls available, however.

Thanks for the feedback!
