The center track has from 0hz up.
It often has more bass in it than the LFE track, or any other track...
If the directors or movie-mixers didn't want it on that track, they wouldn't of PUT it there.
If you read the Dolby Atmos spec for large theaters, if I recall correctly, it mentions that in addition to the LFE subwoofers, they recommend having dedicated surround-subwoofers if they aren't large.
I believe they noted that center subwoofers can also be deployed to handle the bass in those tracks.

As I understood it, LFE bass should always flow out of the LFE pin, unless you have the subs set to "off", at which point they'd be added to the mains if large.
If you enable LFE+, that's up to the user.
In any case, there will ALWAYS be a hump in the bass, since the bass is supposed to be 10db hotter than the mains.
The only problem I have with bass management, is that it compresses the LFE track when you enable it!
Every pair of beds added robs it of 6db of dynamics; with 7 beds that's a 21db drop in dynamic range!!!
Not only that, but deep vocals come out of the subwoofer (or get muffled/chopped off), and other effects such as door-slams that should be anchored at the screen, now are coming from all the way AROUND you! That's not likely what the director intended.
Let's say for example, in the nun, you have a ghost stomping in a circle around you. The bass will pan from speaker to speaker. If they are small, it won't pan, it will sound weak and omni-directional (or likely worse... just coming from one front corner!)
Instead of Godzilla completing a circle around you, it will sound like a mouse, with 10db-hot dissociative omni-directional thumping.
Not that you would probably notice in an all-small system... but there are often parts in a movie when the LFE subs are totally silent
, and only the speakers
are producing bass, or vice-versa
. If you enable bass-management, then the subwoofers will always be playing bass, and never from the speakers, which is not at-all the intended effect!
Monotone droning subwoofers UGH!!!
Always use all-large whenever you possibly can and keep LFE+ disabled...
Then everything will play as it was meant
to be played.
What makes matters worse, is they then grow so accustomed to their subwoofers always making bloody noise all the time, that they then wonder why it sounds weak/broken. When the opposite is actually the correct
