You should closely follow Emotiva s speaker placement recommendations with the addition of the following points e left and right front speakers should be positioned so that your TV is exactly centered between them This will help focus your attention towards the screen e For the best overall imaging the left speaker should be set exactly the same distance and angle away from your listening position as the right speaker It is recommended that you use a tape measure to set them up to be the same distance away within about half an inch tolerance If you have a smaller TV the speakers should be no more than two feet away from the sides of the TV If possible have the center left and right speakers at the same height within two feet This will help give a smooth transition when sound effects move from speaker to speaker Ideally the speakers should be no closer than two feet from the rear and side walls in order to reduce any reflections that might upset imaging If your speakers are closer than this you can experiment by adding sound deadening material such as drapes on the walls to reduce any unwanted reflections Continued next page 16 Center Speaker Most movie dialogue is a discrete multi channel format that will come from the center speaker so careful positioning is an important part of a good home theater system Your eyes and ears should focus your attention towards the center of the screen The center speaker
