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

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 3, should be used for measuring the
distance and angle to the listener. The point is
positioned half the distance between the
boundary of the tweeter and the boundary of
the woofer or midrange driver. LYD 5, 7 & 8 are

at a greater distance, it is recommended that you
use a subwoofer to augment the low frequency
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 speakers,
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.
The LYD 48 can be positioned with the woofers
inside (recommended) or outside, depending
on how the equilateral triangle can be achieved
best. Make sure to take measurements from the
acoustic axis of the speaker.
