Acman, I'm interpreting that your last post just above was a clarification of the one just above it, rather than an indication of a second measurement at a different point. Is that correct?
If that is not the correct interpretation, you would be saying that you measured the same 13.1 ohms for the speaker itself and for the speaker plus the wires. That would not make sense, given the 8 ohm nominal impedance of the speaker, and also given the 3.8 ohms you measured for each of the conductors in the cable.
If my interpretation is correct, and the 13.1 ohms just applies to a measurement at the amp end of the cable with the cable connected to the speaker, everything seems consistent. The wires total 2 x 3.8 = 7.6 ohms, and the DC resistance of your nominally 8 ohm speaker itself would be 13.1 - 7.6 = 5.5 ohms, which seems reasonable.
Best regards,
