This is measured at 70 dB at the listening position, no eq.
I'm not convinced the spl meter used is very accurate above 10khz because boosting frequencies above 10khz does nothing to the measured curve. I did try eqing it using the manual eq on my receiver but there isn't enough bands in the correct frequencies to completely solve the problem areas.
This is the result after eq.
Unfortunately the equalizer jumps from 63hz to 100hz, so I can't correct the dip between 70hz-80hz, and it jumps from 400hz to 1khz, and from 6.3khz to 16khz, leaving me with uncorrectable areas. I'm also not a fan of the way it sounds after eq because it seems like the areas I tried fixing required too much boost or cut in order to solve issues around the center frequencies. Either way, pre eq the response is accurate +/- 7dB. I can definitely hear that dip in the midrange though.
