I am getting ready to build a home theater room and I am modeling it using the "golden room ratio". Initially I will only have Dolby Digital 5.1 but will run enough wires to eventually upgrade to 7.1. After reading several articles about this golden rule ratios I cannot find anywhere where it discusses exact speaker placement for 7.1. Does it matter? I would think it would make a huge difference, especially for the surround speakers. Anyone know of some good articles that explain speaker placement in more detail?
