Well, here is my solution. These are replicas of the old Altec Valencia grills, often seen on the Heathkit versions. They were created by Stephen Merryweather. He has some in stock if anybody else likes this sort of vintage look. I don't know whether they affect the sound, but upon first few listenings, I can't hear any differences. That may change as I get used to these speakers and more picky. If that happens, then I still have the rat color problem.
