I am researching the setup requirement for a good A/V space. A good reference site to start with is SoundStage. Let's start with audio (2 channels) speaker placement. Center of the woofer should be RW x .276 from side wall, RW x .447 from rear wall, to minimize reflection. RW = room width. This means a normal 10 ft wide room will push the speakers 4.5 ft into the living space. Difficult to accomplish I'd say. It's all about minimizing reflection. Glass (windows!) is bad. Padded walls? Unlikely either. This is not going to be easy.
