Excellent
Now in an attempt to check the behavior of the elephant in the room, I used Bill’s link YouTube
Then using Audacity I applied 12dB/oct HP filter at 20,40,60,80,100Hz as a crude way of emulating the low cut-off effect of progressively smaller sealed loudspeakers (listen through headphones at first).

With the 70Hz high Q smallish sealed loudspeakers I don’t lose anything compared to the OB+W sub, only sense of space.
The missing fundamental effect is very strong with organ notes (proper harmonic structure).
It seems to be a well build-up resonance in the Hall (maybe a mechanical resonace of the organ). I checked another Tonhalle Zurich organ recording and it is there. Same shape at 4.7Hz.>Edit also the one at 15Hz.

Maybe, but when the signal is flat to 1Hz I do wonder about the analysis. I've had some results with audacity I just didn't believe in the infrasonic region. In that case the analysis was slightly out but there was still some strange non-music down there.
Edit: Missed your post George. Interesting. Will google around to see if I can find out more.
Second Edit: Tonhalle got a new organ in 2017. less than 30 years for an organ is almost unheard of!

There's always the mostly folklore articles about 10Hz resonances.
Ahh just thought about it again. Maybe a HVAC fan blade causing air turbulence - that would be circa 250 RPM?
For those interested in organs Organ details - Kuhn Organ Builders Ltd some info on the new Tonhalle organ. Best comment in that is
I assume that means it was great for solo stuff but no so good for orchestral accompaniment.

Q: How do you get two lead guitarists to play in perfect unison?
A: Shoot one.
If you want bass there's always sunn0))) all dropped A bass guitars. YouTube
I prefer it to Bach even though they also like to perform in churches.

It’s not easy to get away from J.S.Bach. (e.g. 60ies-70ies British rock was full of him)
I see big tubes in there.
