5. When you begin to hear this artifact, place a piece of tape on the floor
and mark this location. This is the inner edge of the "Zone of Neutrality."
6. Repeat the procedure with the side walls, positioning yourself with the
zone you have established above. Continue to listen for the point in the
room where your voice loses the added bass energy from the wall behind
you, and continuing until there is an obvious interaction with the oppo-
site wall in front of you. Do each side or speaker location individually.
The Zone of Neutrality for any room runs like a path, parallel to the walls all
around the room. Adjacent to very large windows and open doors, the outer edge
of the Zone of Neutrality moves closer to the wall and becomes wider. If you
extend the inner and outer boundaries of the Zone for the side walls and the front
wall (behind the speakers), they will intersect. You will now have two rectangles on
the floor on either side of the room, which is your Zone of Neutrality for each
channel.

The location of your listening position is as important as the careful setup
placement of your speakers in your room. The listening position should ideally be
no more than 1.1 to 1.25 times the distance between the centers of left and right
channel tweeters on each speaker. Therefore, in a long rectangular room of 12' x
18', if the speaker tweeters are going to be 9' apart, you should be sitting 9'11'' to
11'3'' from the speaker. This would be about halfway down the long axis of the
room. Experiment carefully for best low frequency response.
