Adjusting the Feet and/or Spikes
Under normal circumstances your subwoofer will be
commissioned by your retailer or consultant, who
will have been trained in their installation by KEF.
KEF strongly recommend that you do
not attempt to level your loudspeakers
single-handed. Recruit the assistance of another
adult - or consult an authorised KEF Reference
outlet for assistance which may be chargeable if the
purchase was not made through them originally.
The spike/locking nut combination supplied is
designed to provide small adjustments, not to
compensate for seriously irregular floors.
Best results will be obtained if the subwoofer is
level and stable. Check the general stability of the
subwoofer by gently rocking it from side to side,
front-to-back and diagonally. Adjust the height of
each foot to ensure that the subwoofer does not
rock at all.
Subwoofer Positioning
The listening room is one of the most variable
elements in the hi-fi chain and its effect cannot be
emphasised too strongly, nor can its effects be
reliably predicted. This is where the room
correction feature on the Reference Series 209
subwoofer becomes such an important feature.
As the sub-bass (low frequency) sound produced
by the subwoofer is close to omni-directional
positioning of the subwoofer is less critical than
with full range conventional speakers.
However, it is advised that the subwoofer is not
positioned too close to the listener.
It is often recommend that subwoofers are not
placed in the corners of the room, near soft
furnishings (which will deaden the sound) or near
reflective surfaces (which may brighten up the
sound). The room correction feature of the
Reference Series 209 subwoofer will help
compensate for all these effects.
KEF recommend you to place the Reference
Series 209 subwoofer in a central position in the
room and execute the room correction setup.
This is an initial compensation for your unique
room. Then move the subwoofer into a few
acceptable positions and compare the sound.
Pick the location which gives the most satisfying
sound available from the room.
When the subwoofer is in its final chosen
position, then repeat the room correction setup
and select the preset equalisation setting to
optimise the sound further.
