"The purpose of the voice coil wire is to produce a magnetic field."...

..."The wire going from the amp to the loudspeaker terminals serves a different purpose, so there's no basis for comparing their performance."
Actually, there is basis for performance comparisonss The purpose of the "wires" in both examples you cite is to conduct an electrical current. Physical configurations of conductors may be arranged to take advantage of the consequences of a "flowing" electrical current. In the case of a voice coil, low loss and low mass are also usually considered important. In the case of audiophile grade speaker cables, visual impressiveness is typically as important as electrical properties if not more so. ;-)
