Tweeters are easy to blow. Just turn the volume up past 2 o'clock and see. If you turn the treble up AT ALL you are guaranteed to blow tweeters. I've always liked Infinity, and I sold them at retail over twenty years ago, but the Infinity Emit tweeter was absolutely the easiest tweeter to blow on the planet. If you listen like you have been, you'll continue to blow them. Sorry, I know it's a bummer.

I can tell people who are judgmental just by looking at them...
