the main benefit of higher or high impedance coils is
- that you can use a thin but longer or in general a longer wire
- and so the coil can be designed not very flat but with greater height or more wraps
- so the magnetic field of the coil produced by the flow of current has a better linearity (in the area of the magnet pole)
- result can be a better linearity of the movement of the driver
- a greater max. moving width of the driver (in german language called 'Hub', the maximum length or distance the driver diaphragm can move from the zero positon without being in the nonlinear area of the magnetic field
- better linearity for high levels
you don't get something for nothing... higher impedance means more wire, more wraps... which means more magnetic flux... which means more dynamic response given the same mass of movement... means better tighter sound with more headroom.
think about it this way, why do sports cars have more powerful engines? it is all about no compromise performance
