I watched/helped a tech remove my 801N woofers. The driver is held in by the perimeter screws, and there is a paper gasket around the edge. IIRC the connectors are not hard-wired. Removal is much easier with the speaker laying on it's back. The screws are removed and a bent or curved pick (or maybe a screwdriver) can be inserted into a screw hole to pry the driver up enough to grasp with your fingers. I recommend having a helper especially if removal is tried with the speaker standing up.
Not difficult but take your time and be careful...
