Apple Soundtrack Pro 3 - Manual (Page 340)

• With the center speaker directly in front, the Left and Right speakers should be
positioned 30 degrees away from center at about a 60-degree angle aiming for a spot
3 to 6 inches behind the mixer’s (or listener’s) head.
Note: This angle can be reduced to 45 degrees or extended out to 60 or even 90 degrees
and still provide satisfactory results.
• Place the surround (rear) speakers at about 110 degrees off center (to the sides and
somewhat behind the listener). To ensure one cohesive soundfield, do not position
these speakers too far to the rear.

Note: It isn’t always possible to place the speakers where they’re supposed to go due to
obstacles in the room (doors, furniture, and so on). You can overcome some bad speaker
placement by calibrating your system with a sound pressure meter and a calibration DVD.
This way, you can make sure each speaker is providing the appropriate volume.
