I have an a Polk set up using a CS400i center & RT55i's for everything else. My problem is I cannot stand the Tri-Laminate tweets in these things at all. They are just simply too damn harsh sounding to me. I don't know if this is just the nature of these tweeters or something with the crossover design. I am used to speakers that use silk type tweeters so this could be cause for some of my problem. Anyway my question is would it be possible to change the tweeters out for something like a silk dome without changing the crossover or, maybe some kind of mod to the crossover to help tame it down a little or both? I have thought about getting a pair of silk domes from Scan-Speak or Morel & giving them a try & see what happens but I just wasn't sure if this would be a good idea. I'm not concerned with having to modify the bezel or killing my warranty or any of that so that is not of concern, I just wont something a little smoother sounding. By the way I should mention that I tried out a pair of the newer RTi70's in my home as a comparison to my RT55i's & they sounded much smoother & less harsh than my 55's in the high end. If I could even get the sound they had I would be happy. Thanks for any advice.
