I like to just talk frequencies, and skip the textual categories, so there's less confusion.
Also like to think in terms of subs, and mains.
In this thread, the idea I was trying to present with the "get the kick drum out of my butt" post, was that a sub has a directional concussive force, and multiple subs often lose that auditory and physical sensation.
For me, a sub typically handles 100Hz down. I use a linear-phase 96 dB/oct xover between sub and main,.
I am 100% certain, the bulk of concussive force like from a kick drum, comes from my sub(s).
I know like most of us, that transients including bass transients, are full range phenomena. But i also know, concussive kick is dominated by 100Hz down.
And often gets smeared as multiple subs are added.
It is very easy for me to mute any driver section, solo any driver section, solo any LCR speaker playing stereo summed to mono, play stereo, or matrixed LCR.
Each LCR speaker which are the same, also has the same sub underneath it.
So it's easy to discern things like a sub's concussive force alone, or whether multiples add for more force, or whether a track has mono sub or stereo sub content....etc.
Highly recommend a setup like this for sheer playing around/learning/experimenting..., my2c .
