PLACING LOUDSPEAKERS IN THE MONITORING ROOM
Here is a quick introduction to monitoring loudspeaker placement.
•
Place the loudspeakers in their expected positions before cabling anything.
•
For most applications, the two-way 8130A loudspeakers should be located within 1.7-2.5 meters
(5-8 ft.) of the primary listening position.
•
Attempt to place all loudspeakers at ear height for the person in the primary listening position.
If a loudspeaker is higher than ear height, tilt and turn the loudspeaker toward the listening
position. Genelec two-way loudspeakers feature a vibration-isolating monitor stand, the IsoPod™,
which enables the positioning of the loudspeaker towards to the primary listening position.
•
Aim the acoustic axis of all loudspeakers towards the main listening position both horizontally
(turn towards the listening position) and vertically (tilt towards the listening position).
•
Position subwoofer close to the wall(s).
•
Remember that all audio cables must go to the subwoofer first and then to the loudspeakers.
Make sure that enough cable length is available to move the subwoofer around the room to find
a location of optimal performance.
The following sections provide more detailed information about placing loudspeakers in a monitoring
environment.
Full-Bandwidth Loudspeaker Placement
Minimum Distance From a Wall Behind a Loudspeaker
Genelec two-way 8130A loudspeakers should be placed so that a minimum distance of 5 cm (2") is left
behind the loudspeaker for amplifier cooling and rear opening reflex port sound radiation.
Low Frequency Cancellations
In general, when a loudspeaker's front baffle is more than 0,3 meters (1 foot) away from the wall behind the
loudspeaker, a reflection from this wall can cause a cancellation of low frequencies and hence reduction
of bass output. For two-way loudspeakers, low frequency cancellations in the 40 – 80 Hz frequency range
should be avoided. Cancellations in the 80 - 200 Hz range should also be avoided if possible.
Recommended Distances
Translating this into distance recommendations shows that loudspeakers can be placed close to a wall at
a distance less than 1 meter (3 ft.). Distances between 1 and 2.2 meters (3-7 ft.) should be avoided.
Loudspeakers placed more than 2.2 meters (7 ft.) away from walls may suffer from cancellations around
the low frequency cut-off of the loudspeaker limiting low frequency bandwidth. As a rule of thumb, the
