I Just did a similar test with right and left....I just don't think these LCR speakers sound as good as my RF-3....am I crazy? They don't sound "Full"...I tried with and without the LF1-EX sub...it just seems that the LCR are missing something. Maybe it's cuz I'm used to Klipsch horns and the larger fuller sounding cabinet? I have all the speakers setup just about the same. even the 39" above the floor (tweater to floor). I'm fixing to return all the speakers unless someone can tell me a tip, trick. I Have almost an equalateral triangle with the proper toe-in as well. Speakers are around 30 degrees from viewing position. I think all is optimal. My wife says the same, she notices little to no difference, if anything she thinks the klipsch bring the movie more to life. Ugh, i was really hoping these would be all they were cracked up to be. Now I have to spring around 100 bucks to ship them back....
