805 maxtrix tweeter


 Trying to clean my B&W Matrix tweeters.  Cleaning out the ferrofluid has any one done this? Does anybody know how to take it apart? There are four screws that you remove but it's still mounted by the positive and negative post.
It should come apart after you pop it out and get the waveguide face plate off. 

For these reasons and more, ATC no longer use ferrofluid tweeter designs but almost all other manufacturers still do.
Removal of the pin terminal is were it makes me nervous. Do I just pull them out? After I take the four screws out it only lists up a 16th of an inch if not less because of the pin terminal.
