I finally have my HT room where I am happy with it. Check out my system showcase pics....ls7z06. I think I have everything calibrated to where I am very, very pleased. The Polk RTiA7's, CSiA6, and FXiA6's with the DSW Pro 500 all powered with the Onkyo 806 have all turned out great. I am however plotting to add those 2 rear surround channels at some future point. I have extra sets of RTiA1 bookshelfs, OWM3's, and Monitor 50's to choose from for use as rear surrounds. I just dread the wiring. Given my set up, which of these 3 speaker sets would be best for Rsurrounds?
