the bass level at lower frequencies and may
cause asymmetrical spatial imaging.
Although the 7050A is magnetically
shielded, it may cause colour distortion if
placed near to very sensitive video monitors
or computer displays. Move the subwoofer
further away or try turning the driver side of
the subwoofer away from the screen.
Minimum clearances to walls
or other objects
Do not cover the driver side of the subwoofer
or place the subwoofer so that there is less
than 10 centimeters (4") of free space in front
of the grille.
Make sure that the space underneath the
subwoofer is clear from obstructions. Thick
carpets may block the ventilation clearance
needed for cooling the amplifier unit.
The reflex port side (opposite of the con-
nector panel side) should always have a
clearance of at least 7,5 centimeters (3") to
any objects to ensure proper functioning of
the reflex port.
Flush mounting the subwoofer
If the subwoofer is flush mounted into a wall
or a cabinet, it is important to ensure ampli-
fier cooling and unrestricted airflow from the
reflex port. This can be done by making the
recess 7,5 centimeters (3") wider than the
subwoofer. Place the subwoofer into the right
end of the recess with the driver side facing
the room. This leaves sufficient 7,5 centime-
ters (3") of free space on the reflex port side.
The height and depth of the recess should
not be any bigger than what is needed to fit
the subwoofer flush with the wall surface.
Setting the input sensitivity
The 7050A is set to the same sensitivity
as the 1029A/2029A/2029B monitors in free
field conditions. However, when placed near
reflecting surfaces the sensitivity typically
needs to be attenuated due to increased
room loading. A typical starting point would
be -4 dB. This is achieved by adjusting the
rotary level control on the amplifier plate. The
use of proper measuring equipment together
with careful listening is highly recommended.
The maximum attenuation is -18 dB.
