Painting tweeter faceplate

I have pair of these speakers (ATC SCM40):

Is painting the tweeter plate quite easy? The dome seems to be fixed to
the plate in some way, and I can't see how to get a neat finish (as in
this pair - the photo shows it well).

How is the bass unit fixed to the baffle? I'd guess 'from behind', but
if so, how does the baffle come off?
