Attenuating component tweeters

So, this is probably a little premature, but I've read that some of the Focal component tweeters run a little harsh. Is this issue best solved by just using EQ or by adding an attenuator at the tweeter? I like the idea of cutting down the highs a bit at the source and then EQing only when necessary.
