Please be explicit - device is rather ambiguous, state exactly which device.
The first quote implied to me that 'device' meant the phone/tablet running the wiim app.
But as the phone/tablet would likely be at the listening position then the second quote implies that it's not the home app device, and therefore that the subwoofer has a mic and that is used.

All WiiM devices have a build-in microphone. It's of course those that are used for now.

Would the Sub pro also have a built-in mic? As far as I can see the photo, I don't see any mic hole on the back panel

I Believe the mic is always the device that has the WiiM Home app (is the app that measures and calculates). None of the WiiM devices has a mic...

No. As stated all the WiiM devices have built in mics for synchronization and that mic is the one inexplicably used for speaker/sub alignment.

No. There is a microphone on the back of the WiiMs. The phone/tablet microphone is used for RoomFit, not for timing calculations.

What?! Never saw that. Really didn't knew that.

WiiM Ultra also?!

 

[pjorgenunes]

WiiM Ultra also?!

I checked it and it has one...

It's useful only to measure latency of audio chain... but between several devices I doubt it would be usefull... but who knows

 

[slartibartfast]

What?! Never saw that. Really didn't knew that.

WiiM Ultra also?!

Where have you been? When speaker/sub alignment was introduced everyone assumed it would use the same mic as the room correction but WiiM had other ideas. It was the subject of much ridicule at the time.

Hi Team,

The auto-calibration feature is designed to improve audio quality by aligning the timing between your main speaker and subwoofer. When a WiiM device, like the WiiM Amp or WiiM Ultra, connects to your speaker and subwoofer, it assumes both audio paths have the same delay. However, if your powered speaker, amplifier or subwoofer adds extra audio processing, it can introduce a slight delay.

This mismatch in timing can cause the high and low frequencies from your main speaker and subwoofer to sound out of sync, affecting the overall audio quality. Our auto-calibration feature uses...

• WiiM Support

Hence my question, and we've been caught out by non specific references to 'device' before.

 

[Wiimer]

Yeah

No mic hole can be seen in the rendered image, but what looks like a small hole can be seen next to the power terminal. If this is the mic hole, it's a strange position..

Thanks for the info

Thank you very much for your feedback! Currently, subwoofer and speaker synchronization is handled using the device’s built-in microphone, which provides basic time alignment in most usage scenarios. However, we recognize that for more demanding listening environments, using a microphone placed at the listening position could significantly improve synchronization accuracy and overall sound performance.
We take this suggestion seriously and are currently evaluating more advanced technical solutions, with the goal of further enhancing calibration accuracy and user experience in future updates.

Thank you for your detailed question — we’d like to take this opportunity to clarify:
The time alignment currently performed uses what we refer to as the "device's microphone", which specifically means the built-in hardware microphone on the playback device itself (such as the WiiM Amp), not the microphone on the phone or tablet running the WiiM Home App.
The term "microphone at the listening position" refers to, for example, a phone or tablet placed at the main listening spot, where its microphone would more accurately capture what a listener actually hears. This method could theoretically provide more precise calibration results.
We fully recognize the potential benefits of using a microphone at the listening position and are actively evaluating whether future updates can support this more flexible and accurate synchronization method.

Despite the Sub pro claiming to 'Works With Everything', it does not clearly explain how it works when connected to third-party amplifiers. Can I still use all the tuning features of the Sub pro when connecting to non-WiiM devices?

And is it possible to integrate both wireless and cable into the system?

E.g.
WiiM Ultra > (wireless) -> Sub Pro
WiiM Ultra > AVR > (cable) -> Sub Pro

Use the Sub pro wirelessly when listening to music on the Ultra, and use the Sub Pro cable-connected to the AVR when watching movies. Is this possible?

Thank you.

From the reply above it seems the sub does not have a microphone, implying (automated) time alignment can only be done when used with another wiim device.

Isn't time alignment in the WiiM environment pertinent only to multiroom synchronization? In which case the sub's synchronization would be associated with its linked main speaker(s) and streaming/amplification stage...so in other words, the microphone-equipped WiiM device driving those transducers.

There's different time alignment features in the WiiM. One is for inter-unit/multi-room sync (which should use internal WiiM device mics) and the other is for subwoofer to mains (which should use mics in/attached to the controlling smart phone/tablet).

I think that is why they use the device mic for speaker/sub alignment. They use the same algorithm as for multi-room sync. I can't believe the WiiM post above says that measuring at the listening position "could theoretically provide more precise calibration results". It definitely does which has been demonstrated by a member moving their Ultra to the listening position.
I also can't believe it's taken ten months to start actively evaluating using a microphone at the listening position.

I think you need to balance that against the absolutely huge amount of work WiiM have put in elsewhere. It's not like they've been sat doing nothing.
