I know with my headphones (Hybrid canalphones, actually) I can detect
down to around 10hz, anything lower is inaudible. I designed my
headphone amp with a ~15hz corner frequency high pass in it's input
stage (AC coupling, to get rid of any DC bias before feeding the signal
to the op-amp)
It sounds beautiful, very rich tones.
There is something about a big pipe organ with extremely low registers.
Occasionally at church they'll pull what I think is the 16' stop, and it
sounds incredible, there's something about that deep rumble the big
pipes put out...
