The relationship you mention is "Let the product of the LF and HF -3dB
frequencies equal 600,000". Familiar examples are 30-20,000Hz;

Oh, well, there goes 50 years of "20 to 20,000 cycles" shot to hell.


There's not much music below 30 Hz, only a few pipe organs.

That is not true. There are kick drums and electric bass
guitars, electronic synthesizers and all manner of stuff between say,
100 Hz and 30 Hz.

Your point being ... ? I said BELOW 30 Hz.


I meant *below* 30 Hz as well. I did not type that, but I should have.
All we need to know is that when somebody removes it on the
right program material thru the right playback, its absence is
apparent. Doesn't happen often.
