Ok right now I'm running as seen in my page below a Yamaha RX-V730 and Energy Take 5+1's, now I'm trying to figure out what the best way to setup my rears would be right now they're horrible placed one sits about 4 feet off the ground on top of my corner computer desk and the other about 2 feet off the ground on a bookshelf. I Plan on mounting them on the walls but have this question should I place them on my back wall or try to set them up on my side walls? I've read both ways, also to take into consideration is that I've got a 6.1 setup (be it matrix do to my F*** up) and plan on eventually adding another take center channel in the rear will this also affect how I should place my rear speakers. I've been doing alot of research on this and most of the stuff I've found is at Dolby's website. My other thing is most my software is DTS since I prefer that format so is there different standards for how you should place for DTS vs DD? any help would be appreciated on this.
