BigWill, there are no RTi9s. There 8s, 10s, 12s. I have seen the 8s and 10s at Circuit City. I have RTi8s, CSi5 center, and FXi3 surrounds. I also own some Axiom M22s. Darth, you can't go wrong with either manufacturer. Both companies were founded and are run by people that really care about sound and the quality of products they produce. My M22s are very good $400 bookshelf speakers. My RTi8s are very good $800 floor speakers. I think the CSi5 is the best speaker I own. So, I would not advise you to replace it. If you are going to replace any part of your current system, replace your sub. I was unimpressed with Polk subs - even the 404 - so I got a Velodyne that does a great job. Most here would argue that SVS and Hsu are both better than Velodyne - so they likely are. If I were you, I would try to listen to some Axioms - and get some if you love them - or just order some to try them out. But I would also argue out of the other side of my mouth that the safe answer is to stick with the Polks to match your current speakers - you will definitely not be disappointed. I was recently at my boss's house and heard his Outlaw/Hale/MK system - and went straight home from there to listen to my system and tried to develop a case of upgradeitis because I liked his toys - but I couldn't say that I found my system deficient in any way - recognizing that his system is more appropriate for his larger room, but I didn't think that I could put his stuff into my room and get an improvement. But that's just me and my ear may be as sophisticated as many others here...
