My guess would be an attempt to try to cut down on high frequencies through the speakers, either noise or maybe an attempt to build a rudimentary crossover if the speakers are wired in series. Putting the two caps in series halves the capacitance, so it's effectively like putting a 75uF cap on there. But I'd be concerned about reverse biasing the caps unless there was something else connected to the side that's tied together.

No idea on the coil...

Quoted from thedefog:

you can just wire two normal ones like this to make a bipolar one

Ok, sure, that makes sense.
