Table 1 shows some typical settings in various
situations. Figures 3 and 5 show the effect of
the controls on the frequency response.
Tabletop
This switch is recommended to be switched to
“1”, when the loudspeakers are placed on a table
or similar surface so that there is a reflective sur-
face between the loudspeaker and the listener.
Such a placement typically causes a boost at
certain bass frequencies, which the “Tabletop”
function is designed to compensate for.
Treble
The “Treble” adjustment allows modifying the
high frequency response of the loudspeaker.
The G Three has one setting, -2 dB for smooth-
ening down an excessively bright sounding
system, the G Four provides two attenuation
levels, -2 dB and -4 dB and one boost setting,
+2 dB.
Bass
The “Bass” control offers three attenuation
levels for the bass response in frequencies
below 1 kHz, usually necessary when the loud-
speakers are placed near room boundaries
or other situations when the bass sounds too
dominant. The attenuation levels are -2 dB, -4
dB and -6 dB. On the G Three, the -6 dB attenu-
ation is selected by setting both “Bass” switches
to “1”.
Low Bass
The Low Bass control provides bass attenua-
tion at the lowest frequencies of the loudspeak-
er’s bass reproduction. This may be necessary
if these deep bass frequencies sound dispro-
portionally strong. The G Three has one setting,
-4 dB and the G Four provides three attenuation
levels: -2 dB, -4 dB and -6 dB.
The factory setting for all tone controls is “0”
to give a flat anechoic frequency response.
Always start adjustment by setting all switches
to “0” position. Measure or listen systematically
through the different combinations of settings to
find the best tonal balance.
Mounting considerations
Align the loudspeakers correctly
Always place the loudspeakers so that they are
aimed towards the listening position. Vertical
placement is preferable, as it minimizes acous-
tical cancellation problems around the crosso-
ver frequency.
Maintain symmetry
Check that the loudspeakers are placed sym-
metrically and at an equal distance from the
listening position. If possible, place the system
so that the listening position is on the centerline
of the room, but not exactly at the center of the
room and the loudspeakers are placed at an
equal distance from the centerline.
Minimize reflections
Acoustic reflections from objects close to the
loudspeakers like desks, cabinets, computer
monitors etc. can cause unwanted blurring of the
sound image. These can be minimized by plac-
ing the loudspeaker clear of reflective surfaces.
Minimum clearances
Sufficient cooling for the amplifier and function-
ing 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
structure. The surroundings of the loudspeaker
must always be open to the listening room with
a minimum clearance of 5 centimeters (2”)
behind, above and on both sides of the loud-
