In order to get the best performance from your Dynaudio speakers,
care must be taken in positioning them in the listening environment.

Acoustic Axis
The acoustic axis is an imaginary line passing
through the center point on the speaker and is
used for positioning. This point, shown in Figure

and angle to the listener. The point is positioned

speakers are designed to be positioned vertically
and pointed directly at the listener.

at a greater distance, it is recommended that you
use a subwoofer to augment the low frequen-
cy response. This will help the speaker system
achieve a reasonable volume without overdriving
the speakers.
Listening Angle
To begin with, the speakers should be placed so
that the drivers are oriented vertically, with the
tweeter directly above the woofer. This orientation
ensures correct time alignment between the high
and low frequencies as they arrive at the listener.
Horizontal Angle
The speakers should be placed so that they
create a 60 degree angle between the speak-
ers, as shown in Figure 5. The easiest way to
accomplish this without measuring the angle,
is to create an equilateral triangle between the
speakers and the listener. In other words, the
distance between each speaker should equal the
distance from each speaker to the listener. Make
sure to take measurements from the acoustic
axis of the speaker.
