Parallel of course.This the diagram ?
If you disregard any resistance/capacitance or inductivity of the wires (which I think we can do) then that is all 3 in parallel. Or isn’t it?
But it does not matter THAT much as zobel is quite forgiving as to the values and even if the resistor value is too high for 3 drivers in parallel (as opposed to 1 RAB) overshooting resistor value compared to the calculated one actually helps. Cap could be made x2 as the inductance decreases in parallel arrangement.
