The range “below 50Hz” is not ULF range. Below 50Hz is regular LF or regular bass region. The whole definition if ULF is that ULF is the LF message that is not registered and recognized as sound. Playing ULF you shall not be able to not only recognize music but to be able to say in most of the case the music even is placing. If you can say what is being played by ULF then it was not ULF but regular bass channel. In my estimation ULF stars around 25Hz with shaper then 2 order filter.
So, the most of what being discussed in thread there is not ULF but bass channel. There is absolutely nothing wrong with it and in some cases the bass channels might do low enough that ULF would not be necessary. Still, I feel that question tone in ULF range is like cooking a soup with poisoned mushrooms and to think about a proper amount of salt in it.
