"...the long wall is rarely the best wall for speaker placement..."
Let's just say this has not been my experience with the dozens of locations and systems I have owned. And there is no need to try to discount the opinions of others. The suggested set-up does not work with all loudspeakers and is not seen in any true hi-fi system installation that I know about. Perhaps it's geared for working systems (that have different requirements) rather than home systems, I don't know. The best nearfield system I put together had the loudspeakers 5 feet out into the room and the seat 6 feet from that in a tiny room. The soundstage was awesomely wide and deep, way beyond the room boundaries. Perhaps my best system to date. That didn't happen by luck.
I wish I could push my speakers against the wall and get good sound but that hasn't been possible with the loudspeakers I owned in the last 45 years. YMMV.
