Positioning the monitors
In order to get the best performance from your Dynaudio monitors, care must be taken when positioning them in
the listening environment. The room greatly affects the sound so the position and angle of the monitors relative to
the walls, ceiling and floor is critical in any listening environment.
Acoustic axis
The acoustic axis is an imaginary line passing through the centre point on the monitor. As shown in Figure 2 , use
this method for measuring the distance and angle to your listening position. The point is positioned half the
distance between the boundary of the tweeter and the boundary of the woofer or midrange driver.

The Core 7 is designed to be positioned vertically and pointed directly at the listener.
The Core 47 has two versions with the woofer on either side of the tweeter and midrange drivers for either
horizontal left or right side placement.
The Core 59 is designed to be used in either vertical or horizontal position by rotating the Orbit Baffle.
The Core Sub is a side-firing subwoofer where the front baffle has the logo and LED indicator.
Room boundaries
Each surface in the room constitutes a boundary for sound; floor, walls, and ceiling. Room boundaries will reflect
sound to one degree or another depending on the surface material; hardwood, drywall, carpet etc. If possible,
please avoid placing monitors very close to any boundaries. The closer a monitor is to a room boundary, the more
anomalies you may experience in the low-frequency response of the system. Placing a monitor close to more
than one boundary (e.g. in a corner) creates even worse problems in many cases.
Conversely, placing monitors exactly halfway between room boundaries may over-excite fundamental standing
waves in the room, making the bass response less reliable. This is also the case with regard to the listening
position. These room anomalies are always present, but proper placement of the monitors according to the
listening position will reduce their effect.
A good rule of thumb is to place monitors somewhere between one quarter and one third of the distance
between room boundaries as shown in Figure 3.
