Grille

A dedicated grille assembly is supplied with your
subwoofer. However, if you wish you may
remove the grille by gently pulling it forward
toward you. The grille is held on via ‘pegs’ that
locate into the front baffle grille-peg sockets.

If required, the grille may be removed during use.
KEF suggest the removal of the grille for serious
listening, however we strongly recommend
replacing the grill after use. 

For cleaning purposes, the grille should 
be removed from the cabinets and brushed
lightly with a soft brush. Alternatively, use 
a variable suction vacuum cleaner, with soft
brush attachment.

Your Reference Series Model 209 subwoofer is
guaranteed against manufacturing defects in both
materials and workmanship. For further details of
how this guarantee affects you, please read the
enclosed Warranty leaflet. 

It should be noted, however, that failure of the
loudspeaker due to abuse, improper or
inappropriate use and/or operation or damage
caused by other faults in your system are NOT
covered within the terms of the guarantee.

Service Information.

Loudspeakers are inherently reliable and rarely
give trouble. It is important to remember that
faults arising in any part of the reproducing
system will be heard via the loudspeakers and
therefore when faults occur, careful and analytical
diagnosis will be required to locate the actual
source of trouble.

Faults in a loudspeaker will be audible on all
programme sources. A fault which is evident only
when playing CDs but not, for example, when
using a radio tuner is unlikely to originate with
the loudspeakers.

Service problems should be discussed in the first
instance with the dealer from whom the
loudspeakers were originally purchased.
Generally, warranty claims are best handled by
your dealer. 

However, in case of difficulty, please contact:
