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.
I am not pushing anything. I just gave some "empirical feedback" that
the lowest piano key is 27.5 hz and for example the lowest double bass
note 32.7 hz (C extension) or even lower. If you want to reproduce the
fundamentals and not just overtones, you probably need a subwoofer.
and i'd like to stress that subwoofer != lfe.
Did I pretend anything different?! There is obviously no LFE channel in
Ambisonics, but in the cited cinema formats you had. (10.2, 22.2)
And I was also referring to some former 5.1 discussion. (LFE needed for
music mixes, or not.)
In this sense, we have a mixed discussion. (You still could argue that
LFE is not needed in a 5.1 mix; in practice, there could be some issues
without LFE. Depends maybe on the intelligence of your equipment...)
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).
You will experience still your 10 listening octaves if you turn up your
hf amplification a LOT and fry your speakers... :-D
Best,
Stefan
