Those side surrounds are what I have been battling. From that right side surround speaker to seating position is one biggggg bay window. SO I have been having a bear of a time for surround speaker placement. So in your opinion 12.5 ft from the viewers is not to far away?? So if I stuck with this setup and switched to direct firing speakers in the rear and then QS8's for the sides would this help to make up for the placement issues that I am having to deal with??

Thanks for the response I do greatly appreciate the help
