MAINTENANCE

Once  you  have  found  the  best  possible  placement  for 

Gradient  Helsinki  speakers,  there  is  little  need  to  move 
them anymore. If you have to carry speakers, use the upper 
part of the woofer hole in loudspeaker frame for lifting and 
carrying.

Oiled plywood surface will slightly change its color during 
the years. Direct sunlight makes this darkening faster. This 
aging is normal for real 

wood and will give your Gradient 

Helsinki a unique look and feel. It does not affect the louds-
peaker performance or the structure of the wooden frame.
However, it is advisable to apply small amount of furniture 
oil with cloth to wooden surface regulary once a year. This 
treatment  protects  loudspeakers  against  aging  and  the 
effect of sunlight.
