Soon as you can, insert a tapered prying tool, like a painter's 5-in-1 tool, between the frame and the baffle. Keep pressure on to stretch the silicone as you go around with a utility knife or NEW single-edge razor blades, maybe.
You want to cut the silicone itself, not the baffle, of course.
Your hardware store has a wire saw to use as Rob suggests above, as well, like a guitar string with "teeth," rings on the ends to pull it....
