I have a pair of rt800's that sound great but never were just quite right. At high volumes they become very harsh and hard to listen to. But were very detailed at lower volume. As some of you might no I got a pair rt600's that were damaged during shipping. Well I hooked them up to see if they were ok musically and they were! They sounded better than my rt800's. Whitch didn't make any sense to me. I thought maybe because I was more in the 600's power range with my amp b&k 105x2. The 600's only handle 150wpc where the rt800's can handle 250wpc. Well out of curiosity I switched the tweeters from the 600's to the 800's and viola! The speakers I always wanted. Is there such thing as a tweeter being kinda blown up or just wore out?
