For some reason, when I listened to the pro60's in person, the metal tweeters didn't sound tinny or harsh at all. I heard a couple of other metal tweeters before, and I absolutely hated them, so when I was going to listen to the bostons, I even had the mindset of "I'm not going to like these"
Turns out I liked them so much, I bought them on the spot. The really funny thing is that it sounds better than the silk tweeters I heard. and like I've said before, I dont like the high tinny sound.
I'm going to have to listen to my components for a while before making a definitive choice and if I'm not 100% happy with them, I may pick up a set of hsk165's or some id's. Listening to speakers in a room will be different than listening to them in my car.
