It does seem odd, perhaps Michael will have some ideas. If I run tests over a loopback connection with artificially induced distortion the results are not affected by adding a HP on the stimulus. I wonder if room resonances are having an effect on the process and the HP is attenuating the lowest resonances? Could try higher HP frequencies and see if the results stabilise.I removed the sock, and added a LR2 high pass at 20Hz. The result of this FSAF measurement confuses me, as the total distortion is reduced through the entire spectrum of the speaker, right up to 20kHz, and significantly so as well. Is there a reasonable explanation for such a change in TD throughout with only a 20Hz high pass applied?
