33Hz RULEI found that 33Hz is the practically sufficient low end.
Characteric frequency of a bass drum is 33Hz or higer.
You may not hear sound below 33Hz if with orchestra.
Try listening Saint=Saens's 3rd Symphony in an orchestra hall.
It has super low frequency to 16Hz, but you cannot hear it, though your skin may detect it.
What you can hear is 33Hz and higher if with orchestra.
33Hz is easy for MCAP-CR applications with 5" driver.
Below 33Hz is much more difficult with an audio system.
Try 5" an application at reasonable cost.
