Hi hawk,

Those coil-looking things are inductors.
Have you tried a simple test like using an AA battery, and connecting the leads to the input posts on each driver? If the driver is working, the cone will make a "click" and move either inwards or outwards, depending on the polarity you used to connect them.

This will not damage the drivers. If there is no movement of the cone, then the drivers are gone or fused.

Last time I checked, the drivers are from $48 to $52, including shipping.
