In a 2 or 4 conductor cable, inductance is lowest when the conductors are very close to each other. Thin insulation and twisting will lower inductance. Braiding not quite as much. (the conductors are about parallel to each other, but the current is flowing in opposite directions, that's 180 degrees)
Cable inductance only matters for a few loudspeakers that have very low impedance at high frequencies. (think Apogee and some Martin Logan speakers)
But most other loudspeakers have rising high frequency impedance, so induction doesn't enter the picture with them.
