Hi, Bob I like Waymer's set up from the looks of it at the link you provided except that I would flip the placement so my speaks are in front of the short wall firing into the length of the room (a rectangle). Also, even tho the wall behind my seat is diffused with open back record cabinets up against the wall, I still prefer that the distance from the front of my speaks to the wall behind them not be the duplicate of the distance from my ears to the wall behind me. I think the centerfront of your speaks should be a minimum of 44" from your side walls or greater and think 60" more or less from the wall behind them is the ideal neighborhood for your speaks. Some modest toe-in to your ears in an equilateral triangle and all you then gotta do is get your bass even with fine adjustments. Now, I listen to a lot of classical music recorded on location and this works best for me for balance and a cohesive and expansive stage. For studio recordings I will from time to time scoot my seat back some for a bolder in room presence. But that's just me and I think MS placement is a distortion in itself. Unless I am mistaken, it was designed for show rooms where listeners are frequently not seated front and center- a general kind of sound in other words- and the near wall placement will amplify a speaker's low end. The room sound I want is the room sound in my recordings, those that have it. Cheers.
