The factory setting for all tone controls is “OFF”
to give a flat anechoic response. Always start ad-
justment by setting all switches to “OFF” position.
Measure or listen systematically through the dif-
ferent combinations of settings to find the best fre-
quency balance.
Mounting considerations
Align the loudspeakers correctly
Always place the loudspeakers so that their acous-
tic axes (see figure 1) are aimed towards the listen-
ing position. Vertical placement is preferred, as it
minimises acoustical cancellation problems around
the crossover frequency.
Maintain symmetry
Check that the loudspeakers are placed sym-
metrically and at an equal distance from the
listening position. If possible, place the sys-
tem so that the listening position is on the cen-
terline of the room and the loudspeakers are
placed at an equal distance from the centerline.
Minimise reflections
Acoustic reflections from objects close to the loud-
speakers like desks, cabinets, computer monitors
etc. can cause unwanted colouration of the sound
image. This can be minimised by placing the loud-
speaker clear of reflective surfaces. For instance,
putting the loudspeakers on stands behind and
above the mixing console and tilting them down to
point the acoustic axes to ear level at the listening
position usually gives a better result than placing
the loudspeakers on the meter bridge.
Minimum clearances
Sufficient clearance for cooling of the amplifier and
functioning of the reflex port must be ensured if
the loudspeaker is installed in a restricted space
such as a cabinet or integrated into a wall struc-
ture. The surroundings of the loudspeaker must
always be open to the listening room with a mini-
mum clearance of 3 centimeters (1
3
/
16
”) behind,
above and on both sides of the loudspeaker. The
space adjacent to the amplifier must either be ven-
tilated or sufficiently large to dissipate heat so that
the ambient temperature does not rise above 35
degrees Celsius (95°F.)
Mounting options
The Genelec 8020C offers several mounting op-
tions: The Iso-Pod™ (Isolation Positioner/De-
coupler™) vibration insulating table stand allows
tilting the loudspeaker for correct alignment of
