AJ.......Thank you. The way the living room is set up is about the only way I could make the sound system work. As unusual as it is I get an excellent sound stage and imaging at that sweet spot on the couch. I have acoustic panels and base traps in the room which help to produce good sound under less than optimal circumstances. Everyone who has heard this system has been amazed. Heck, I'm amazed. I am fortunate to also have my dedicated two channel room downstairs in the studio. There's plenty of good music in this house.
As for temperature, I keep the house at 79° day and night. Ceiling fans running on low keep the air moving just enough so I am comfortable at that temperature.
