Additional Notes on Speaker Placement
the same distance from the main listening area as the Left and Right speakers.

■Placing the LCRs below the screen is generally preferable to place- ment above.
■The subwoofers do not have to be extremely close to the LCRs— anywhere in the room is all right, but placement will affect the consistency of the low bass. Experimentation is in order.
■Dipolar surrounds should be located high and to the sides of the listeners instead of behind them, in order to place the audience in the surround speakers’ null. If the viewing area is more than one row deep, place the surrounds halfway back within the seating area.
■If architectural constraints prevent ideal placement of dipolar sur- rounds directly to the sides of the listening area, it is generally best to err on the side of being a bit further to the rear of the room.
■When using traditional speakers for the surround channels, the speakers should be located high and somewhat behind the listen- ers, with the speakers’ output directed toward the rear wall rather than at the listeners.
■The surrounds should be relatively high, often near the ceiling for the best results. And they should be located equally distant from their adjacent walls/ceilings, or else one will have more
•Some allowance must be made for those installations involving relatively small screens, such as 35"
•With regard to subwoofer placement, it is important to leave your- self some leeway during final installation for minor movements to minimize room modes. Corner placement will yield the most deep bass, but it will usually be lumpy and irregular, as this placement excites the maximum number of standing waves.
•Use multiple subwoofers if more bass output is needed. This also has the advantage of allowing one subwoofer to fill the other’s “holes” created by room modes, while reducing distortion by giving each subwoofer an easier task.
