ljgerens,
The tweeter needs to be gently pushed out forward from the mid range speaker once you pull the screw and rubber washer out. Use a 1/4 drive extension about 6" long. You will need to un-solder the small, thin wires first or the tweeter will not come out far enough to work on it. Purchase a small electronic soldering iron for this purpose. Use a pair of small electronic needle nose pliers to help get the wires out once you melt the solder.
Carefully remove the tweeter dust cover using a 'eye glass' flat bladed screw driver. There are 2 small gaps for this purpose. The voice coil is right under this 'cap'. The voice coil is actually immersed into the Ferrofluid. It sits into the groove annulus of the tweeter. So, I can now understand how this system works. The Ferrofluid is used as a lubricant and coolant for the operation of the voice coil. I'm not 100% certain, but I believe the voice coil dithers up and down some how in this groove to create the high frequency.
Use great caution. Everything is very fragile! Good luck! Let me know how you make out.
