You are correct on all counts. The only acoustic instrument capable of
creating these sorts of levels at sub-audible frequencies is the pipe
organ.

Oranges are not the only fruit.

The orchestral 60" bass-drum (Turkish or Italian Gran cassa)
and contrabass sarusaphone are also close contenders (not as
oranges, but as producers of sounds that are "less like notes and
more like sensations":-)

The Bosendorfer Grand Imperial concert piano is also pretty
impressive in its ability to make the earth (and even the orange) move
with C(0) at 16.45 Hz.

I cannot think of an organ in the UK ( most of which have the 30-note
standard pedalboard to accomodate cantus firmus) with a pedalboard
that goes below this.
