I have the upgraded tweeters in my SongTowers (Jim was out of the standard tweeters, and I didn't want to wait another three weeks..) and while they sound fantastic I doubt that they're that much better, if any, than standard. I am thrilled with the speakers. They are every bit as good as the reviews. The fit and finish is far beyond what you expect to see at this price point; like the listing on A'gon says, pictures don't do them justice.
