So basically for those wanting to resolve the sub-bass rolloff, someone from headphoneadvice and headphones subs gave me some EQ settings to play with and I'd thought I'd share my thoughts:



These are my settings on Equalizer APO:

Preamp: -9.3 dB

Filter: ON PK Fc 20 Hz Gain 4 dB Q 1.1

Filter: ON PK Fc 97 Hz Gain -2.5 dB Q 0.7

Filter: ON LS Fc 105 Hz Gain 5.5 dB Q 0.71

Filter: ON PK Fc 200 Hz Gain 0.01 dB Q 1

Filter: ON PK Fc 250 Hz Gain 0.3 dB Q 2

Filter: ON PK Fc 400 Hz Gain 0.15 dB Q 1



The first three frequencies changes and the pre-amp are from u/Farpun, thank you for the help! They are basically the same frequencies you would find on oratory1990's harman target adjustments. The next three are of my own, as I want to keep the resulting frequencies to -9.3 gain to match the pre-amp, so I would keep my crystal clear and intimate mids. I do miss the high's, but I'd rather sacrifice that than my bass which is more important for modern hip hop tracks I listen to.

Let me know your thoughts and if it would solve the sub-bass rolloff.

You might find more responses and thoughts over in the dedicated HD 600 thread. And you'll definitely find no shortage of other people's PEQ suggestions and profiles.
