i am not an expert on tweeters but the RSD's tweeters seem very good. they can get loud but also have a crisp, very clear sound to them. way better than the harsh kappa perfects i had back in the day.What exactly do you mean by the tweeters being "a diamond in the rough"? I don't quite understand that.
I think I'm going to look into the RSd's a lot closer now. Since I'll be saving money getting these instead of the X's, I'll use that to get some more deadening and do more of my car. Thanks a lot.
