Or the microphone!

Even Neuman only quote a 20kHz upper limit on their M149 which, at three
grand (pounds) is probably the microphone equivalent of Festool.

Saw a chart in a book once which showed the frequency ranges of various
instruments, microphones, amplifiers, speakers etc. The limiting factor
was the microphone and if the microphone doesn't pick it up you aint gonna
hear it unless it's generated elsewhere.

Where you err your assunmption in the above is that the spec'ed
frequency range of a high quality mic is what is known as it's "flat"
frequency response, usually quoted as between two numbers, say 20 Hz to
to 20kHz.

... that does not mean that nothing outside that flat frequency
response is not picked up, it just means that it will not be picked up
at the same level as that sound within the flat response.

The "frequency response" of a mic, and its relative flatness at certain
frequencies, is the main characteristic a knowledgeable audio engineer
uses to determine mic choice for a particular sound, instrument or vocal.
