Not sure of your measuring points-the round thing is a matching transformer for impedance matching.As you can see it's a PM speaker,I call it a "pin drive",can't remember the proper term but ron has an article in the tech section about them.
The grill cloth is indeed held on by the ring-I've never been able to get the ring off without damaging it,it is pressed on pretty tight.
