As a newbie to this site, I apologize if this topic has already been covered. With my RX-V440 (a 6.1 system), Yamaha suggests placing all 3 rear speakers on the rear wall, but on Dolby's website, it shows the surround speakers (rear right, rear left) on the side walls. I'm getting a new house built next month, and as I want to hide the speaker cables during construction, I want to get it right from the start!! All suggestions and criticisms will be appreciated :-)
