RE: Some test records comparisons

Thanks, interesting as well. What is the slope in dB from 1 to 10 kHz? The unusual load that was tested to get a target response of ca +/- 0.5 dB between 1-10 kHz, and the drawback is the sloping response above 13-14 kHz.
To use the pink noise, I export the values from a FFT and then convert to "linear" by adding 3 dB per octave. Formula from 1000 Hz: dBcorrected=dBmeasured+3*ln(fmeasured/1000)/ln2
