Speaker Positioning

...then there’s the room.

Speaker position without understanding the qualities of the room or even the equipment rack position is like dealing with 1/3 the problem.

I have moved across the country many times for work...rooms have their own power. Acoustic ceilings can be amazing. Such a
shame they when out of style.

I've always found the Odd Dimensions Placement, advocated by Richard Vandersteen, to work well in every application. In my current listening space, the speakers are located 1/3 of the room width from the side walls and 1/5 of the room length from the front of the speakers to the front wall. Toe-in axes intersect approximately 4-5 feet behind listening position. Acoustical panels on wall behind listening position was money well spent.

Read jim smith’s book on getting better sound. He describes when it’s appropriate to use certain setups even when setting up diagonally in a corner. Most formulas only involve where to place the speakers whereas jim has a formula for the listening chair(s) which is just as important as positioning the speakers. Your better speakers also have time alignment formulas.

When you go to a musical event, you may sit toward the front, back, sides......people may be shuffeling programs, coughing, moving about. I use the classic T , a Bosch laser, and a/v receiver room correction followed by some manual alteration. My ral thought though is dont obsess too much and enjoy the music.

millercarbon is right, but for kicks and giggles. I want to add:  Not all rooms are symmetric in design or furnishings.  A little compensation can be added, for example, for a big Sofa on one side of the room, a large mirror or door, etc.  Listen!
