That thin coil under the top plate is a humbucking coil, and it is placed in series with the voice coil. Most of these speakers were used in situations where the field coil functioned as part of the smoothing circuit for the amplifier's power supply, so they were fed some gnarly DC. You can either leave it alone of disconnect it; I remove them when taking the drivers apart.
No, those weren't my field coil converted 288s on ebay.
