Because the human ear is far more sensitive to the mid range---as this is where the human voice is.

Typically, we boot the low end. Why? Because bass frequencies take a lot more power to move the same notes. Look at the size of a bass driver compared to a high frequency driver...

Finally, at low volumes we boost the highs. Why? Because, when combined with a mid cut and a low boost, a high boost will create the perception of loudness.

Now, the mid buzz can be reduced or eliminated with the EQ. First, flatten out all of the bands and lower one frequency band at a time until the buzz goes away. That's the resonant frequency.

If you need more room to cut, flatten out EQ and then move all faders up an equal amount, say +3. Then start cutting mids until buzz stops.

Next, there may be harmonics that cause a low frequency to generate a mid buzz.
I think a better solution would be to fix the panels correctly since he may not want to alter his listening experience?
