Well, just upgraded my tweets in my RE comp set to some 1" silk CDT's and now I'm looking to upgrade the x-overs. I need suggestions, I have been looking at the CDT 560's and I'm just wondering if there is anything else I should bee looking for. I'm really quite clueless when it comes to this, so I really don't want to go active. If I can get a nice passive set than that would be great. Anyone have suggestions?
