Scanspeak revilator tweeter removal ??

Hi- Can someone tell me how to remove my scanspeak tweeters from my Montana SPS Speakers without damaging the finish around the tweeters ? I have removed the screws from the tweeter and the woofer above. But I can't get either one to break loose without taking a chance on marking up or damaging the finish. I hoped I could get in through the woofer and then push out the tweeter. But I can't seem to get either one to break free. Please help if you have an idea.
Thanks so much
