The frame of the grill is probably the most offensive to the energy flow from speaker into room. Have you noticed that the high end speakers are getting more and more into rounded off edges, narrower cabinets, while some even slope from front to back.
Notice the tweeters of say the B&W Nautilus 801. It mounts on top of the cabinet and is tear drop shaped. It ain't just for looks, folks.
It is a continuation of the mounting the speakers as flush with the surface of the cabinet as possible.
I believe the manufacturers have to supply grill cloths strictly for marketing pruposes.
Someone mentioned that Vandersteen recommends leaving them on. Have you ever seen a Vandersteen naked? They are really ugly. And for all their good qualities at a reasonable price, a faily major criticism is the frame around the speakers supporting the grill causing diffraction of the small speakers.
