The BEQ conversation increasingly seems like a tomato/tomahto discussion to me, since people are using the term "more ULF" in different ways. Perhaps it helps a bit to frame the discussion in the following way. It is very hard to hear frequencies below about 20Hz, in conjunction with other bass sounds, until the volume of the ULF sounds approaches about 100Hz. That number probably varies depending on the noise floor of the room, the overall volume level, the specific hearing of the individual, etc. But, 100db is a pretty good number to use for discussion purposes.
So, if there is ULF content in a movie that is significantly lower than 100Hz, when the volume of the rest of the bass track is played at about 100Hz or higher, then for all practical purposes, the <20Hz content simply isn't there. Perhaps it adds a little almost imperceptible bass weight to the audible bass content, and perhaps it adds a little low-bass TR (which may take less SPL to be perceptible) but if the volume of the ULF content is very low, then the ULF is pretty much not there at all.
If, on the other hand, we raise the volume level of the ULF content, which is rolled-off either deliberately or otherwise, while keeping the other bass levels about the same, something interesting happens. At about 30Hz and below, approximately a 5db increase in volume is perceived as a doubling in loudness, so an increase in very low-bass SPL immediately makes it more noticeable than it was. Our attention is drawn to it more, compared to when it was virtually (or completely) imperceptible.
That may be a good thing or a bad thing, depending on the individual, but it is definitely a thing. As a somewhat neutral observer to the discussion, I think that everyone is right. How's that for a cop-out?
BEQ doesn't create ULF that never existed in a soundtrack to start with, but it also doesn't simply increase the loudness of that ULF content. In many cases, it may change the ULF from non-existent, by reason of inaudibility, to perceptible, thereby enhancing the overall special effects. So, it doesn't add to the overall percentage of ULF in a movie, but it may absolutely add to the overall audibility of ULF in a movie.
Just thought I would throw that distinction out there, for what it's worth.
Edit: There is something else that I think may be worth noting. People who are already implementing a significant low-bass house curve may be doing the equivalent of Bass EQ for all of their movies. If they are lifting their <30Hz or <20Hz frequencies, relative to the other frequencies, then they are probably accomplishing the same thing that BEQ does, but on a broad-stroke basis.
BEQ is more movie-specific, but the net effect effect may be very similar with either BEQ or a global low-bass house curve. In fact, the person with the global low-bass house curve may end-up with more ULF, in general, because he is lifting the low-frequencies even in movies that are not
rolling-off the ULF.
