Parallel connected voice coils increase efficiency 3dB and sensitivity 6dB over using a single voice coil.
Series connected voice coils increase efficiency 3dB and does not alter sensitivity over using a single voice coil.
Have a look at section 3.5 of the Shiva white paper:

It includes a table of how different configurations of voice coil and drivers add up.
Nice one,
David.
