tweeter replacement, original glued in


I've an old pair of Michael Green monitors with a VIFA tweeter that a troglodyte burned.  I tried removing the tweeter by unscrewing the 4 and tapping out.  Seems now that the whole thing is glued in.  Any great ideas for tearing this out without destroying the cabinet face and mounting surface?  Thank you in advance.

I'll try it.  Just do not understand why it is glued.


Probably the builder was worried about maintaining an air-tight seal. A little overkill. :)

Thank you everyone for advice.  Ended up going Jeremy Clarkson on it, grabbing the center ring with tweeter core removed with plumber's wrench and yanking it!  Out it all came.  Yes, it was glued.  New tweeter soldered in and done.
