-20dB is a multiplication by 10%. Not difficult to implement, but usually not available on manually controlled EQs unless you stack two bands. I haven't actually confirmed this with testing yet, but won't those resonances still increase decay time at those frequencies after equalization? I'd like to see post-EQ waterfall plots.
