Comparison of Pro 80 and Pro 82 frequency responses:
Pro 80 FR
Pro 82 FR
It is crucial to understand that the red and blue lines in the Pro 82's FR must be ignored - they represent the "bass boost" feature.
The green line is the only one we care about.
Pro 80 - The mids are about 7dB (from 300Hz to 3.5kHz) recessed compared to the bass
Pro 82 - The mids are about 3dB (at 1KHz) to 5dB (at 300Hz) recessed compared to the bass
Conclusion - Pro 82's mids are less recessed than Pro 80's
Pro 80 - The treble has a sharp dropoff of 8dB from 3.5kHz till 4kHz, followed by a sharp rise of 15dB till 5.5kHz
Pro 82 - The treble has a much slower decline of 10dB from 1.2kHz till 3.5kHz, followed by a slow rise of 15dB till 8kHz.
Conclusion - Much slower changes in frequency response are the reason why Pro 82's treble doesn't get as hot as Pro 80,
and clarity is improved. Moving the peak from 5.5kHz to 8kHz must have contributed to removing sibilance.
