Hello all,
My name is Christian, I am from the US, attending school in Italy. Currently working on installing a digital organ in the chapel of my school...I have been learning about the intricacies of audio systems for a couple years now, and I am mainly interested in audio systems for digital organs, especially with regards to bass (most organs can go down to 32hz, some 16, and very few 8), which is difficult with organs because they have to be able to sustain those frequencies at ~100db pretty much indefinitely.
Read plenty of threads, hoping to learn a lot more from this community!

Welcome!
What sort of digital organs are you working with? Years ago I heard a very good digital organ which I think was a Johannus. It used nearly a dozen separate speakers for its output, instead of combining all the sounds into just one or two speakers.

Buongiorno and welcome! Grew up in Italy (Rimini)
Wow, 16hz, 8hz? Can anyone hear down there? Maybe an Elephant or Ferret?

Hello AMDguy, nice interests!
john65b you will fell it, no need to hear it at all. The church I go for concerts/mass has two sets of 32' pipes , 16hz full power.

In the past I have worked with Allen organs, but now most of my work is with VPO's. I really like Grandorgue because, well, it's free 🙂, but my current project is with Hauptwerk.
As for the extreme low frequencies: Yes, organs can get that low. There are only 2 organs in the world with full length 64' pipes (8hz), and both of them are reeds, which are much more harmonics than fundamental tone. 32' on the other hand, is much, much more common, and a fair number of organs have them. The reeds are fun and cool, but like with the 64's they are mostly harmonics. The flues on the other hand, are truly incredible...for example, a 32' contra bourdon is almost pure fundamental tone. If it's a powerfully voiced rank, then you don't really hear much of anything in the bottom octave, but I have seen/heard a few that will literally make the entire church thunder and shake. There is absolutely zero substitute to hearing a proper organ in person.

It has that at this church:
Contra Bombarde
Flute Resultante
The first is like thunder, the second just shakes the building with pure pressure. Very nice !

Yes the bombarde is a reed (some are very deep and dark, others are just noise to the point of being annoying/useless...all depends on the voicing).
The 2nd is (going from the name) a resultant stop, which are pretty cool. Pulling that knob and playing a note actually plays 2 pipes/ranks; a 16' and a 10 2/3' rank, which together to "create" a 32' using harmonics. It's a very cool concept that can work shockingly well if executed properly. This is also used with 32' + 21 1/3' to create a 64' resultant.
