subwoofer. Place the subwoofer into the right  
end of the recess with the driver side facing  
the room. This leaves sufficient 7,5 centime-

Servicing and adjustment must  
only be performed by  
qualified service personnel.  
Opening the amplifier unit is strictly  
prohibited except by qualified  
service personnel.

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.  
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.  
Always use a mains power  
connection with protective earth.  
Failing to do this may lead  
to personal injury.  
Warning!  
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.  
This equipment is capable of delivering sound  
pressure levels in excess of 85dB, which may  
cause permanent hearing damage.  
Maintenance  
No user serviceable parts are inside the  
amplifier unit. Any maintenance of the unit  
must only be performed by qualified service  
personnel.  
Safety considerations  
Genelec 7050A subwoofer has been designed  
in accordance with international safety stand-  
ards. However, to ensure safe operation and  
maintain the unit in safe operating condition,  
the following warnings and cautions must be  
observed:  
Flush mounting the subwoofer  
Guarantee  
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  
This product is supplied with a ONE year  
guarantee against manufacturing faults or  
defects that might alter the performance of  
the unit. Refer to supplier for full sales and  
guarantee terms.  
Do not expose the subwoofer to  
water or moisture. Do not place
