Leveling my new(to me) SVS' Subs with manual PEQ

[brad1138]

I downloaded a tone generator for my laptop, utilized my external DAC and UMC-200 Prepro analog inputs. Using my SPL meter, I plotted the response graph at sitting location, every 2 Hz from 20 to 100. Then learned how to use the UMC-200's PEQ. I learned to set "Q" values. I set the PEQ to +3 dB over about 1 octave at ~38 Hz and -6 over about 1/3 octave at ~ 50 Hz, and you can see the results in the graph below. Tamed it fairly well. I had no complaints before changing it, and haven't had time to listen, but flatter should be better. I decided not to worry about the below 30 Hz fall off. It isn't great to boost the really low frequencies (IMO) and it could be my SPL meter as much as an actual fall off, the SVS have GOBS of low bass.
