So a serious question: For which reason (if any) would you need 28
speakers, which is a speaker count above 22.2? (could also be used to
reproduce TOA, and is an established format for film audio.... )
can't comment on the 28, but .4 is very very nice indeed.
i just built a third-order horizontal system for LAC 2015 with only
two subwoofers, and it took a lot of tweaking to hide all the wrong
localisation cues that two frontal subs bring. unfortunately, putting
them at 0 and 180° and doing a front/back decode was not feasible due
to the room layout and the fact that we also needed the subs for a
frontal LCR stereo system.. i digress. hooray for a real wxy sub decode.
Another question was/is if we need subwoofers for music reproduction at
all. (Most people on this list have denied the need for LFE/subs in
music reproduction before.)
From a musician's perspective, the answer seems to be a clear yes IF
you want to be able to feel very low frequencies.
(OR you use main loudspeakers which are able to reproduce low
frequencies between say 25Hz and 80Hz, if there are any...)

As we see, there is very obviously a significant "LFE range" in music.
You could hear musical low spectrum notes/content also via its
overtones, I guess. The difference seems to be that you could not <

case that we can < hear and feel > all frequencies below the well-known
flicker frequency of about 80Hz, down to the infrasound range?)
In the end, I believe that the use of subs in music reproduction makes
at least some sense.
Otherwise we don't need any sub, and Jörn and Marc could save some
money... :-)
Opinions?
