2.9 Speaker
Cables
Poor quality cables can seriously affect the overall sound of your hi-fi system. KEF recommends that high quality speaker cable be used for
connecting your Reference Series loudspeakers. It is good practice to keep the cables as short as possible. The left and right channel speaker
cables should be the same length otherwise there may be a perceptible change in output level between the speakers.
2.10 Grilles
A purpose designed grille is factory fitted to each loudspeaker. 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 grilles may be removed during
use, but KEF recommends replacement following use. KEF Audio (UK) Ltd request removal of the grille for serious listening.
For cleaning purposes, the grilles should be removed from the cabinets and brushed lightly with a soft brush. Alternatively, use a variable
suction vacuum cleaner, with soft brush attachment.
2.11 Amplifier Requirements and Power Handling
In KEF literature and in the specification table within these instructions are listed a range of amplifier power outputs to match your Reference
Series loudspeakers. Conditions of use (room size, type of programme, preferred listening level) and the nature of the loudspeaker/amplifier
interface vary so widely that it is not possible to lay down hard and fast rules about amplifiers and the loudspeakers they drive.
KEF loudspeakers are built to rigorous standards of quality and consistency and the upper limits of the amplifier requirements shown are
those which the loudspeaker in question should handle without distress or damage when used under normal domestic conditions.
If higher than specified amplifier powers are used, great care should be taken to avoid abnormal conditions such as switch-on surges or gross
distortion, either of the amplifier or the speaker, resulting in power peaks greatly in excess of the ratings specified. Care should be taken as
the possibility still exists under certain conditions (such as excessive bass or treble boost caused by tone and/or loudness controls, graphic
equalisers, etc.) that the speakers can be overloaded and damaged. The lower limits of amplifier power are those necessary to give a
reasonable sound pressure level under domestic conditions.
Remember it is easier to damage the loudspeaker by using a small amplifier driven into distortion by too much volume possibly with bass
and treble boost, than by using a larger amplifier which has power in reserve. If in doubt, ask your dealer.
3.0 WARRANTY
Your KEF Reference Series loudspeakers are 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.
3.1 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.
Loudspeakers cannot generate hiss or hum. Spurious noises of this type generally originate in the electronic sections of the equipment or
even in the programme source itself. Faults in a loudspeaker will be audible on all programme sources. A fault which is evident only when
playing CD’s 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 speakers were originally purchased. Generally,
warranty claims are best handled by your dealer. However, in case of difficulty, please contact:
