Thank you for purchasing KEF Reference Series

loudspeakers. These have been designed to

faithfully reproduce high quality sound over many

years of use and should provide realistic

reproduction of music and speech. Please take a

little time to read these instructions prior to use.

Your KEF Reference Loudspeakers are tall,

slim and extremely heavy. Installed correctly on

a smooth, level surface, your loudspeakers

should be entirely safe to listen to and to

live with.

However, if you have small children, large pets,

the infirm, uneven flooring or unusually thick

carpeting in your home, then correct adjustment

of the foot assemblies is imperative, if safe,

stable operation is to be achieved.

Warning: The metal tweeter dome now has

protective mesh at the centre of the Uni-Q®

driver array; if however this is compromised and

the dome itself is dented, it will permanently

impair performance.

1. Avoid temperature extremes.

2. Avoid damp.

3. Avoid direct sunlight.

4. Clean with the KEF cloth provided.

5. Do not use spirit based cleaners.

If you are at all uncertain about setting up, operating or caring for your system

your dealer will be pleased to assist you.

1. Read this manual carefully, especially the

safety information, before attempting to

assemble and operate the system.

2. Follow the unpacking and assembly

instructions on the cartons. Please note that

lifting the heavier Model 207/2 and Model

204/2c requires two able-bodied persons.

3. Never connect the system directly to the

electricity supply.

4. Trailing cables are dangerous. Ensure all

cables are secure and tidy.

5. When stripping cables use only tools

designed specifically for the purpose ie:

correct wire cutters or cable strippers.

Do not attempt to strip cables with a knife as

this could result in serious injury.

Since its formation in 1961, KEF has pioneered

many innovations in loudspeaker technology and

design. Your new Reference Series loudspeakers

contain one of the latest of these advances -

the KEF ‘Project Austin’ Uni-Q driver array.

In this innovative KEF design, not only are the

mid and high-frequency drivers on the same axis

(co-axial), but their acoustic centres are also on

the same plane (co-planar). The profile of the

mid-frequency driver’s cone modifies the

directivity factor (or ‘Q’) of the high frequency

unit such that both drive units have the same

directivity in the critical crossover region,

where they are operating at similar frequencies.

This unification of the ‘Q’ of the drive units lies

behind the name “Uni-Q”.

Now incorporated in many KEF loudspeakers,

the Uni-Q driver array yields immediate and

readily audible sonic benefits. With no sharp

discontinuity in ‘Q’ at the crossover frequency,

correct tonal balance is not confined to a

single ‘sweet spot’ in the listening room and

is extended to cover a far broader area.

With sound arriving in phase, the sound source

is brought into the sharpest possible focus.

With properly recorded material and as part of

a good quality system, well set-up, loudspeakers

with KEF Uni-Q can reveal the location of each

musical voice in the stereo image with pin-point

accuracy and with a much smoother response

being maintained off-axis - where most people

listen - than before.

The latest Uni-Q array implemented in this

range is a sophisticated device offering a

combination of wider bandwidth and wider

dispersion than its predecessor.

Both the midrange and high frequency drivers

have been symbiotically designed to take us one

step closer to the ideal of a controlled directivity

point source acoustic radiating system.

The 165mm (6.5in.) midrange section has a

shallow ‘Uni-Form’ cone profile which gives

excellent midrange performance but also

provides the optimum waveguide for the

coincidentally mounted tweeter.

This new two piece 25mm (1in.) titanium dome

tweeter has been developed utilising Finite

Elements Analysis techniques to provide

‘pistonic’ motion to a much higher frequency,

eliminating the need for a separate

hyper-tweeter.

It also features a vented pole piece,

increasing the air space behind the dome

providing an extended but smooth high

frequency performance whilst retaining ultra

wide bandwidth source compatibility:

DVD-A/SACD.
