the saving money part happens when you stop pushing every single
loudspeaker down to 20 hz (because extended lf capability equals size
and weight and money, and as we all know, there are many many
loudspeakers in higher-order ambisonics).
it's just not very economical.
frankly, i'm waiting for some well-funded ambisonics wizarding school to
go one step further and start building a mixed-order three-way system
with a few subs, a few more midrange enclosures and many, many small hf
units...
and i'd like to stress that subwoofer != lfe.
i don't need an lfe for music, even less so with all the +/- 10dB
guesswork :-D
but i do like my 10 octaves (or the 9.5 which i can still hear).
i want small speakers with an excellent price/performance ratio that are
easy on the rigging. so all the low frequency gets offloaded to a few
subs. in the example i gave, we used kling & freitag ca106, which were
excellent for the job.
as an aside, i believe that a hypercardioid decode can produce quite
astonishing lf localisation even in a small room, so using for subs is
by no means a waste of resources.
