There is an important reason to maintain full Ambisonic capability to below
20Hz.
It is a MUSICAL one.
Go to a service at a large cathedral with good organ. At the end of the
service, the organist will play something to show off while everyone is
leaving. You can walk around and listen at va

OK Dave - I was mostly referencing to "high quality Subs" in home/small to
medium sized listening spaces..
I do not really have experience in large scal

Hmmm...I have to say that I am simply not convinced (and haven't been for
many years) that the figure 80 Hz is appropriate except in domestic sized
rooms where the wavefronts are too befuddled by the early arrival of
reflections, usually well within a wavelength. I have been able to localise

Why not follow the well known and also psychoacoustic based corner frequency
of 80 Hz with 24/18db octave filters.
If the subwoofers are of good quality and do not produce distortion products
that are in higher frequency ranges,
clean sounds below 80Hz are not possible to localize without h
