Adjusting the Feet and/or Spikes

Subwoofer Positioning

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.

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.
