I can’t get my sub to hold the setting I set it to. Each time it defaults to zero for cross over. And regardless of what I set. It does not sound any better.
I have unplugged and powered my amp up. I have done the same to my sub.
I have run true play again.
All the equipment is up to date and has most recent updates

That’s odd that it isn’t keeping your settings.
I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here.
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

I submitted a diagnostics had a chat with a technical member of their team. And after all of a sudden and done, they asked me to just reset the app.
They told me that the amp or the arc ultra would look after controlling the crossover and the I guess if you wanna call the intensity of the sub.
I told them that’s not the case. I’ve had this now for four years and I could adjust the sub by the plus or minus and also the crossover and it would hold it and you could hear the difference in the output. And they are insistent that that is not the case. I love spending $10-$12,000 on subs architectural speakers all over the place arc ultra amps all over record players. Everything Sonos to be told essentially I mistaken.
So I’m left with it as it is and I’m convinced there’s something wrong like something to do with Your the app requiring a fix that they probably didn’t realize I don’t know. I always like to have it set for +3 And I like to have the crossover I would have it set for that. I believe it was a -85 and it worked well for my room, but according to the Sonos technical help, I don’t know anything disappointed.
Have you tried removing the Sub from the Amp in the app then adding it back?
Clearly, the information you were told was not accurate, so if this suggestion results in the same behaviour, contact support again and ask to escalate if necessary.
Same exact issue for me for both Sub Gen 3 and Sub mini. Tried pretty much everything at this point with customer support, and nothing has worked. Factory resets, wifi changes, latest updates to apps, ceremonial rain dance etc. Sonos support isn’t able to see the issue in the technical report. Likely, it’s the app that’s the issue.
Frustrating as my TV room setup is optimized for Sonos (Sonos Arc, Sonos Sub Gen 3, two sonos architectural speakers, sonos amp, and hardwired via ethernet..except the sub).
Same issue in my den for a sonos sub mini connected wireless to a sonos amp.
Both sub controls work fine, except for crossover frequency reverts to 0, effectively making the subs worthless. Strange considering when the app is working correctly, I believe “0” isn’t even an option for crossover frequency.
Anyone have the same issue, and figured out a fix?
Going back and getting escalated to a higher level at support is likely your best bet. Keep things simple, just discuss the Amp and associated Sub, don't let them wander off to other combinations where there is no Sub crossover setting, only level and phase.
Any support staff confusing Sub settings between an Amp and other Sonos speakers has been poorly trained.
Sometimes the forum moderators can look into things and assist with incorrect support staff provided information.
As I recall the sub crossover setting is only applicable when bonded to an amp with 3rd party speakers. Otherwise say when bonded to a soundbar or other Sonos speakers the crossover is set according to the lead Sonos product. When I get home I’ll research further.
AjTtrek1 is correct. When using a SONOS SUB with a SONOS speaker or soundbar SONOS has already established the best crossover frequency, however, you can adjust the SUB level. When using a 3rd party subwoofer with AMP, you can adjust the crossover frequency.
No, that hasn’t been my experience. Family Room setup is all sonos. Den setup is sonos Amp, sub mini, and B&W CCM664 in ceiling speakers. Same issue there—crossover frequency keeps resetting to zero.
Again, this is only since the last sonos update. Otherwise, the system was fine and stable since installed in 2023.
My neighbor has similar setup, but able to alter the crossover frequency for the sonos sub.
So, no, i don’t believe that my system is behaving as it should. Further, Sonos’ UI is such that if a setting isn’t available due to system parameters, it’s grayed out (for example “enable / disable wifi”), again hinting that this app behavior is a bug.
EDIT

For that setup you shouldn’t have the option to adjust the crossover for the sub as the Arc is the control speaker that sets the crossover point.
Same issue in my den for a sonos sub mini connected wireless to a sonos amp.
You need to explain more about this setup. What 3rd party speakers are being driven by the Amp. I assume there is no Sonos soundbar involved.
OK...thanks for the update on the Den setup…
You are correct that Crossover frequency is not expressed in terms of zero “0”. Crossover is expressed as Hertz (Hz).
Did you convey the above to Sonos Tech Support as they may not have understood if you mentioned reverting to Zero. Sonos Tech Support may have assumed (without confirming) that you were referring to the Phase Control which is either 0 degrees or 180 degrees.
No offense intended but hopefully you’re not confusing Crossover adjustment with Phase Control? 😊
Sonos tech support has been silent since Sunday, but perhaps my current thread with them is with their weekend personnel or something, but i think they understood my scenario, which I believe is similar to the original post on this thread.
My app screen looks just like the original post’s screenshot, with “0 hz” for crossover frequency.
OK…
I want to direct your attention to my screen shots below.
I’m using iOS and App build 80.00.41.
What I want you to notice is the Sub Identification (wording) to the left of the on/off button.
In the first screen shot using NO Sonos Amp the wording is “Sonos Sub”.
In the next two screen shots USING Sonos Amps the wording is Sonos and 3rd Party Subs (even though the subs used are Sonos). Go Figure…
My point here….is your App and system up-to-date as well as the OS on your device?
The apps on your device should look the same.
Sonos_Five Stereo Pair and Sub 3
Sonos_Amp & Turntable with Def Tech Bookshelf Speakers and Sub Mini
Sonos_Amp & Def Tech Floor Speakers and Sub 3
One more point…
In the App where an Amp is the main component (such as in your Den) make sure All Home Theater options are tuned off.
Sonos app and system update are all up to date to the one you listed, and have been since I discovered the issue.
Upon review, the Den seems to be working fine for crossover frequency. Either the glitch was fixed, or it was a mistake on my end (let’s assume the latter).
The crossover frequency issue still persists from my Family Room setup (Sonos sub gen 3, Arc, Sonos Amp, (2) sonos architectual speakers). The crossover frequency shows “0 hz”. I can adjust the slider, but when I return to that submenu, the crossover frequency returns to “0 hz”. Sub level and phase are unaffected by the issue.
It seems possible that Sonos is overriding the crossover frequency since, like in your case, the sonos system could be taking the wheel on the crossover freq. since the system is all Sonos, and so therefore the glitch is more of a UI thing, where in reality the app shouldn’t let me be able to adjust the slider. Hard to say at this point.
I’ve also played around with deleting my Trueplay, turnining it on / off, and trying it over again, but the crossover issue persists.
I would be curious if others with Arc + Sub Gen 3 have had similar issues as
OK…
Hmmm…if the screenshot in your last post is that of the room with the Arc you should not have the screen that is showing.
Are the speakers connected to the Amp acting as surrounds? I’ve never had a system wherein an Amp with wired speakers acting as surrounds was bonded to a Sonos soundbar. Therefore, I can’t provide a credible reponse.
Make sure Sonos tech support fully understands your setup.
FYI, I and others had the issue in the post below. It took me a while to get the point across to Sonos. The issue has been resolved but not without a lot of back n’ forth 😂
I think that is an app problem. The crossover shouldn’t be showing as available at all in that situation. The crossover for sonos subs is determined by the system and not settable. Usually 80hz. The crossover setting is supposed to be for third party powered subs attached to the amp sub output. At least, that’s my understanding. Someone correct me if I’m wrong.
Edit: And sonos subs on the amp, if the amp is not part of a home theater setup?
Sorry, I’m just coming back to this now.
I appreciate other people chiming in. I think what I want to express here is I shouldn’t have to make it look like it’s a third-party component. When everything is Sonos.
The other thing I wanna see this for three years I’ve had all of this equipment and it worked the way that I expressed, and only since changed, and if it was really a matter of the other component is controlling and looking after that crossover frequency hertz why would you even let me adjust it to attend and then when I go back, just keep it default it’s not even there my question
Sorry for the rant I’m stuck in traffic. This is all voice to text.
It’s an issue with the App on your device. I say your device because I can’t reproduce it on my device. Likely Sonos thus far can’t reproduce it either therefore you get the pushback.
As I provided the link to an issue I had it took quite awhile for Sonos to be able to reproduce it. That’s why diagnostics are so important and therefore factory resets are frowned upon as it erases useful data.
Sonos tech support had me to reconfigure my stytem too many times to count and run a diagnostic after each. Sometimes it takes that type of extensive hit and miss testing until the stars align correctly to reproduce the issue.
If the issue were wide spread Sonos could potentially arrive at an answer/solution quickly. As the issue seems to be isolated it will take longer. I’m sure Sonos will find a solution although it may cause you discomfort during the process.
So in the interim keep Sonos Tech involved and ask for escalation to the next level. Be sure to keep the screen shot you published. As a picture is sometimes worth 1000 words.
In your Family room, remove the Amp from Arc Ultra, then check whether the Crossover frequency is still visible in the room’s settings. It shouldn’t be as the Amp is no longer a consideration in the room’s settings configuration. Then, re-add the Amp for surround duty and check the Sub Audio menu to see if Crossover frequency has returned. If it has, then it suggests an app issue.
You could also fully remove the app from your device and install a fresh version to see if that makes any difference.
As it was working, do you have a device with an older version of the app loaded that you could try?
Even a different controller device on the same app version could prove interesting.
