I think if you build it as Wayne suggests you'll be satisfied with the treble based on your listening experience; I have been with 2002 in Stage 4's. I have planned on upgrading comp driver, but somehow haven't got around to it for a few years.... However, there is a mischevious part of the brain that wants to accept marketing or conventional wisdom, or whatever as "reality," and every once in a while that part wants to add some kind of supertweeter or whatever.... But when I listen to speakers that have them, I think it's too 'etched' or 'artificial' sounding and get over it. At any rate, it's fun too play with.
