The relationship you mention is "Let the product of the LF and HF -3dB

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.

The low E string on string bass and bass guitar is, IIRC tuned to 41 Hz
(in standard tuning), and the famous bass drum on Fred Fennell's first
Telarc recording was just about 40 Hz, again IIRC.
