I see the rolloff is consistent, so it has to be something common to all measurements. The thing is, a 10dB drop above 10kHz is pretty noticeable, and sounds like a 1970s tape deck that's totally missing the top octave. So if the rolloff is real, the sound you'll hear is pretty dull. If you were around in the 1970s, think under-dash 8-track tape player.
