the typical concert grand piano, for instance, does about a 27 Hz fundamental, as I recall (and certain pianos go rather lower), and some other instruments are not far behind.
all of the acoustical energy generated at that 27 hz comes from a single finger of the pianist.  the best athletes can generate a peak power of 1 kilowatt with their legs so you can estimate the power of 1 finger.  also you have to consider that the radiating area of a string is only a few square inches, virtually all of the output is cancelled with the out of phase back wave and the frame to which the strings are mounted is orders of magnitude heavier than a speaker cone.  in other words there is simply no issue reproducing that 27 Hz note.
