Thanks for taking the time to post this. It looks like you used the published value of Re rather than measuring it. I realize that you measured resonance values and all the other things that it takes to do T/S calculations, but did you also measure DC resistance of the voice coil at any time? The AC impedance value would be close at some frequencies other than resonance, an octave above or below for example.
