This is a list i have seen quite often as well:


Handy list of eq frequencies.

20 Hz and below - impossible to detect, remove as it only adds unnecessary energy to the total sound, thereby most probably holding down the overall volume of the track
60 Hz and below - sub bass (feel only)
80(-100) Hz - feel AND hear bass
100-120 Hz - the "club sound system punch" resides here
200 Hz and below - bottom
250 Hz - notch filter here can add thump to a kick drum
150-400 Hz - boxiness
200 Hz-1.5 KHz - punch, fatness, impact
800 Hz-4 KHz - edge, clarity, harshness, defines timbre
4500 Hz - exteremly tiring to the ears, add a slight notch here
5-7 KHz - de-essing is done here
4-9 KHz - brightness, presence, definition, sibilance, high frequency distortion
6-15 KHz - air and presence
9-15 KHz - adding will give sparkle, shimmer, bring out details - cutting will smooth out harshness and darken the mix


Here's some more info about Eq's. The "Q" control sets the width of the band of frequencies that will be boosted or reduced!



60Hz with a Q of 1.4 -- Add fullness to kicks.
100Hz with a Q of 1.0 -- Add fullness to snare
200Hz - 250Hz with a Q of 1.4 -- Adds wood to snares
3Khz with a Q of 1.4 -- Adds atack to snare.
5Khz with a Q of 2.8 -- Adds attack to Kicks
7Khz with a Q of 2.8 -- Adds Sharpness to snares and percussion
10Khz with a Q of 1.0 -- Adds brightness to hats and cymbals
