After listening to Bruno Mars when i was your man with only my tweeters, I could here the left tweeter cracking in the beginning of the song with the piano. After putting these tweeters in PIONEER TS-T110, in place of the HT28 I can listen to music without harsh raspy sound before. There not as bright or as crisp, but they sound better that before. I'm still not 100% sure the hertz tweeters are blown tho...
