I have had my new Klipsch HT set up over a month now and I am overall very happy with the set. I have RF-3IIs for the front, a RC-35 center and some RB-25s for surrounds. But yesterday I decided to really try and see just how close the RC-35 sounds in comparison to the RF-3IIs as far as dialogue goes by toggling the center on and off I could switch the dialogue from the mains to the center. I also did this by switching between stereo and Dolby Digital. I was pretty surprised just how different they sound. The upper frequencies are similar and there is a certain characteristic that they both share but still these speakers do not sound at all the same for dialogue. I tried some material from actors and actresses that I am pretty familar with as far as how they sound. The center that is susposed to go with the RF-3IIs is the RC-3II which based on its specs I bet it would sound even less like my RF-3IIs although I have never heard one. I guess I am not surprised because how could Klipsch possibly make a speaker the size of an RC-35 or RC-3II sound anything like the huge RF-3IIs? It makes perfect sence to me now that I have thought about it but it would be nice to have the front 3 speakers the exact same however the only way this could happen is if I went with smaller mains which is something I am not willing to do. It does seem that they do sound a tad more the same when the speakers are set to small. My Yamaha receiver has a center channel EQ so I can try and tweak it some to help it sound more like the RF-3IIs ,also moving it and the mains will help as well but in the end I already know they will never sound the same. I guess I dont really know what the term "voice matching" means...if it refers to dialogue then my speakers are not voiced matched. The system as a whole works well together and since the mains dont do much dialogue then I should never be able to hear any of the differences I heard when comparing the speakers directly. But now I sort of prefer the dialogue sound coming from the mains rather then the center, although I cannot say the center is better or worse, just different.
