There is more to live music than the frequency of any given note especially when it comes to percussion. But, since you insist, the lowest note on a pipe organ is 8.17 Hz. The lowest note on a tuba is 16.35 Hz as is the lowest note on the Bosendorfer Imperial grand piano.
You obviously have not heard a proper system. In the minds of little people if you have not experienced it, it does not exist.
