Hello everyone, I have two quick questions. First, in a 6.1 setup, what is the rear center channel speaker used for. On a 6.1 dvd, is it for more dialogue or is just a third rear surround speaker. Should I purchase another center channel speaker for this position or should I get a third surround speaker? Second, I work at best buy and get a great discount on speakers. I have it narrowed down to either JBL or Klipsch. Right now, I'm leaning toward Klipsch. I know Best Buy is a horrible place to audition speakers, so I was wondering if anyone had any input on these. I will use them primarily for movies (80-90%). JBL seemed to be a little more boomy to me. Would this be better for movies? Any info would be greatly appreciated.
