4. Speaker setup
4.1 Checking up your listening room
A simple ”clapping test” will give you important information on the acoustic conditions in your room. Walk up and
down in the area where you want to set up the speakers and clap your hands loudly. Pay attention to the echoes
refl ected. If they are either extremely loud or extremely long (fl utter eff ect), the room´s reverberation is high and
it is recommended to work with dampers.
To damp the room use sound absorbing elements like carpets and curtains. Diff usors like plants or bookshelves
between the corner of the room and the speakers help to improve the acoustic pattern.
4.2 General setup tips
For best performance the speakers should be set up in front of a hard part of the room (e.g. a solid wall or in front
of no vibrating windows).
If possible, set up the speakers on the longer wall.
Shelves or hi-fi racks located between the speakers (also at the wall) should not be higher than the midrange
driver of the speaker, approx. 1 meter (40 “).
4.3 Speaker positioning
Transfer your room dimensions (longer and shorter side of the room) on a handmade drawing (note the example
given on page 9).
Set the speakers on the drawing.
To fi nd out the optimal position proceed as follows:
Stereo base (a)
At fi rst defi ne the stereo base, that is the distance between the speakers (a). The stereo base should be at least 2
meter (80“) up to 3.5 meter (140“).
Back wall distance (b)
The distance between the back wall and the speakers (b) should be at least 0,8 meter (32”).
Side wall distance (d)
Now evaluate the distance between each speaker and the respective side wall (d).
If you set up the speakers on the longer side of the room (recommended), use the following formula:
d
= Side wall distance
b
= Back wall distance
