Mounting Considerations - Genelec M040 Quick Setup Manual

Setting the tone controls
The frequency response of the Genelec M030 and
M040 can be adjusted to match the acoustic environ-
ment by setting the tone control switches on the rear
panel. The controls are "Bass Level" and "EQ". Table 1
shows typical settings in various situations. Figures 4
and 5 show the effect of the controls on the response.
Bass Level
The Bass Level control is usually necessary when
the loudspeaker is placed near a wall. The attenua-
tion levels are -2 dB and -4 dB. The central position
of the toggle switch (Free space) suits a situation
when the loudspeaker is placed far away from walls.
EQ
The "EQ" switch has two functions (in its central posi-
tion there is no effect):
1. Tabletop EQ
This function is recommended when the loudspeak-
ers are placed on a table. Such a placement typically
causes coloration at low midrange, which the "Tab-
letop EQ" function is designed to compensate for.
2. Bass EQ
This function attenuates bass frequencies below
200 Hz when the loudspeaker is located near a cor-
ner. This can compensate for excessively heavy and
boomy bass reproduction.

Mounting considerations

Align the loudspeakers correctly
Always place the loudspeakers so that their acous-
tic axes (see figure 1) are aimed towards the listening
position. Proper vertical placement is preferred, as it
provides the best linear frequency response around
the crossover frequency.

the loudspeaker as shown.
Maintain symmetry
Check that the loudspeakers are placed symmetri-
cally and at an equal distance from the listening posi-
tion. If possible, place the system so that the listen-
ing position is on the centerline of the room and the
loudspeakers are placed at an equal distance from the
centerline.
Minimize reflections
Acoustic reflections from objects close to the loud-
speakers like desks, cabinets, computer monitors
etc. can cause unwanted colouration of sound. This
can be minimized by placing the loudspeaker away
from reflective surfaces. For instance, putting the
loudspeakers on stands behind and above the table
and tilting them down to point towards the listening
position usually gives a better result than placing the
loudspeakers directly on the table.
Minimum clearances
Sufficient clearance for cooling and functioning of the
reflex ports must be ensured. The minimum clear-
ance of 3 centimeters (13/16") behind, above and on
