I'll be needing some covers/grills for my speakers. I have a set of some supernice altec lansing 4.1 speakers. i'm not too worried about the sub, but i'll need something for the tweeters. not sure where to find some grills though. the tweeters themselves are 4 convex sides (not a straight square.) but i suppose that's irrelevant. the holes for the screws are located in the corners, and the diameter of the entire thing is 3". tried the local radio shack with no luck.
