I always considered the central point or the heart of upper-mids being 3k. When we discuss iems, lots of people consider that peak on the target curves, upper-mids and that's probably why I think this way. it doesn't make sense to me for treble to start at 2k.That may be why I wasn't quite on the same page with you re the K371's upper midrange. I just go by what's on the graphs, which probably isn't correct. So...
Bass: 20 - 200 Hz
MIds: 200 Hz - 2 kHz
Treble: 2 kHz - 20 kHz
If you consider mids as going up to 5 kHz, then I can see why you might be bothered by the peak in that range on the K371 at 3 kHz. Makes more sense to me now.
Some divide the frequency spectrum into...
Sub-bass: 16 or 20 - 60 Hz
Bass: 60 - 250 Hz
Low Midrange: 250 - 500 Hz
Midrange: 500 Hz - 2 kHz
High Midrange: 2 - 4 kHz
Presence: 4 - 6 kHz
Brilliance: 6 - 20 kHz
Presence & Brilliance together = treble or high notes.
Wikipedia defines bass as C0 (16 Hz) to C4 (256 Hz) And sub-bass as below C2 (60Hz). The lowest note people can hear in ideal circumstances is G-1 (12 Hz). Treble according to their definition is C7 (2 kHz) to C10 (16 kHz). Which leaves C4 (256 Hz) to C7 (2 kHz) as the mid-range.
Ultrasound = above human hearing, usually defined as higher than 20 kHz. Though some humans with good ears can hear as high as 28 kHz. Infrasound = below human hearing, usually defined as lower than 20 Hz.
People do refer to upper-mids being too forward, and they are usually meaning around 3k or so. And my sense of the positions is based on statistics of what I've inferred from the way most people referred to the regions.
