Microphone specifications tend to be about as loose as a cow with amoebic dysentery. Even some big names and high cost mics leave of frequency limits and such data.

You're very correct on this. This is the published "20-20000" frequency response for a very popular microphone. Its down 10dB at both 20 and 20,000Hz. It's +3dB at 8-10K. If this was an amp or interface they would be thrown out as junk! They are typically +/- 0.5dB or better across that range.
Oh yeah, it's the reponse curve of a Neumann U87.
