WEEE Consumer Notice

Please be AWARE

When BK design a subwoofer it is built to withstand a certain amount of excessive use, to this end we 
design in circuits that will help protect the drive unit and amplifier from damage. That said these circuits do 
have a limit and therefore can be over-driven if the user insists on turning up either the drive level from the 
source, or the gain controls on the subwoofer. When the subwoofer is over-driven it will sound distorted 
and if pushed extremely hard may emit a cracking noise. If this happens then please turn the gain down   
from your source. Prolonged misuse in this fashion will damage the subwoofer, such damage is not 
covered by warranty

It   is worth remembering   that a subwoofer is there to augment your sound system and not to overwhelm   
it. If you feel that there is not enough bass then there may be room   issues that could easily be overcome 
by a different room   placement. It could also mean you simply have too small a sub for your room or taste.
