There is no comparison between the Alpine tweeters and the Kenwood eXcelon's. The Alpine's are night and day different. No sibilance where it was very noticeable with the eXcelon's. If I had to choose a discription... Bright and Tight. when I am able to put Barbara Ann back in the car we will see what these Alpine's can do. My Punch P3 sounds different with the signal running through the 3Sixty.3. It is the one speaker I did not adjust the EQ on. It sounds better though.
