I came across a set of Polk RT16's a few months back but was unable to use them because of a damaged woofer. So in the closet they sat. Until now. I found a replacement woofer on Ebay and now have them in my system and all I have to say is wow! I can't believe how much cleaner sounding they are over my RT800i's. The 800's tend to have a somewhat cluttered presentation. They can get pretty dynamic but they aren't the cleanest sounding speaker. And I hate the rolled off highs. A lot of people like a warmer speaker but I know there's detail missing in the top end because I've heard it on other speakers.
The RT16's on the other hand are amazing. They are more forward but I'm hearing things that the 800's just can't get across. The sound stage seems to be very wide and deep, a trait also missing on the 800's. Now the 800's aren't bad speakers. Again, they are warmer sounding. They're good for movies. They just seem to be outclassed by the 16's. Does anyone know why Polk messed around with crossover in the RTxxxi series? They had a good thing going with their first generation RT speakers, I think. Now their most recent RTiA speakers are another story. I can't wait to get my hands on them.
