Can grills be removed from Cambridge Soundworks?

I need to remove the metal grills from a set of Cambridge Soundworks New Ensemble's. I cannot figure out how to remove them without destroying the boxes and grills.
yes they can takes of all things the tip of a cork screw with a twist slightly into the grill at the lower edge and pull smoothly outward then continue all around the edges until pulled out...don't twist the cork screw all the way in just the tip.
Hey guys,

If you see this post (a year after-the-fact), I have an Ensemble question:

Is the only difference between the original Ensemble and the New Ensemble, that the New has switches on the rear of the satellites?
