Hello - I have a pair of RT 16 that I bought new around 1996. They have seem relatively little use in the time I have owned them and have spent most of their time is storage. When not in use they we used very infrequently. I have resurrected them recently and have been very glad that I did. They really rock. I took the grills off yesterday and noticed that one of my tweeters has started to change colors compared to the other one. The color is getting closer to bronze or gold as opposed to the original silver color. As far as I can tell, the sound is not impaired. Just curious if this is a know issue and whether I should consider replacing the tweeter.
Thanks in advance!
