Hey guys i am wanting to upgrade my front 3. I mainly use it for movies and sports. I currently have the hkts 15 setup. i live in an apartment so its not bad. But like always after awhile you have the urge to upgrade. My brother in law has polk monitor series. i think they are the 50's and cs1. i like the way they sound. What i was looking at was the rti series..maybe the rti6 and csi6..they would cost me around 550-650..any ideas anything better in that price range? its a 15X15. I would keep the hk surrounds for the time being than get the rti4's..i appreciate your help.
