The RTi8 sounds great. It is very detailed, crystal clear, in your face sound, and the sound stage is awesome. I upgraded from Athena F2s and these are definitely a lot better. I just unboxed my CSi5 and I calibrated my system. Now to watch a movie and see just how great this center speaker is. I have "The Bourne Identity" playing at the menu select screen and wow, there is a lot of bass coming from the center. No center that I have had or heard had that much bass coming from it before (Athena AS-C1, Polk CS2).
