1.4 Listener´s position
Eventually find out about the optimal listener’s position.
The distance between the listener’s postion and each speaker should be the same as the distance between the
two speakers (a), i.e. the listener sits at the top of an equilateral triangle.
The distance from the rear wall to the listener ‘s position (c) should be at least 0,8 meter (32’’).
1.5 Setup and fine-tuning
After you figured out the speaker´s position, install your hi-fi system and set up the speakers.
For a fine-tuning slightly move the speakers symmetrically around the initial position and/or play with the toe-in
angle.
If you have chosen the optimal configuration, you can screw the spikes in the speaker´s feet (depending on what
type of floor you have).
If you have normal carpeting or solid flooring, you won’t have to use the spikes (see 2.2 Spikes in Sound Optimiza-
tion).
Run the speakers for at least 100 hours and do another fine-tuning, if necessary.
