Typically rewiring the spkr wouldn't require unsoldering the voice coil just replacement of the wires connected to the primary of the opt and field coil. If you need to remove the cone/vc then you would need to unsolder the voice coil. It's soldered to the secondary of the opt and has a little spring contraption that holds the wires in place. It pinches them so you can pry them out gently. Remove the screws along the perimeter of the cone and the one in the center and the cone can be removed.
