    GRAS 43AG is the same coupler as what was used by Harman, except they used a stereo version (L and R ears in a single unit).

    Different dummy head ears geometry are different leading to small differences in low treble/treble between HATS/KEMAR/HEAD, but if a coupler is IEC compliant (ie. 318/711), the FR and impedance curves are specced within tight tolerances. Plus, they come with individual correction curves typically. So not sure what you're on about...

    Thanks for pointing out them. Just tried to overlap several sets of measurements between 43AG and 43CA, and confirmed they were quite consistent, regardless of slightly different pinnae settings. I might have been more careful.
