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.
