More specifically: maybe there's a difference between "good for 2-channel" and "good for 5+ channel". \n\nI recently setup some new speakers (KL-650-THX) in a home theater room I'm building out; and in test listening on movies and mutli-channel music (Elton John's DVD-A of Goodby Yellowbrick road, or Dire Strait's Brothers in Arms); I've really loved the sound. In particular: this is the first time I've really enjoyed a center channel [in a home setting] and found it improved clarity. \n\nBut when I listen in two channel; though the quality of the sound remains excellent, the ability to "fill the space" seems a bit lacking compared to the 2-channel setup before them (Philharmonic 2s). \n\nI'm thinking that the difference might be that the Klipsh's have a more focused dispersion... they localize a bit more easily as they interact with the room a bit less. I wonder if this trait (or something like it) is why I so love these in multi-channel (the speakers interact with each other less than "normal") and why I don't like them as much in two channel; and why my experiences with most of my two-channel setups are the opposite. \n\nThoughts? Is there a difference in ideal "room interaction" between 2-ch and 5-ch?
