Your speakers are heavy. Take care when
removing them from their packaging.

Looking after your loudspeakers

Always take care when lifting heavy objects.
Lift the speakers out by their sides.

Carefully remove each loudspeaker from its packing
carton. Do NOT lift speakers via the polythene bag.
Be especially careful when removing large floorstanding speakers.
The carton top says, “Open other end”. So you,
– Open the bottom
– Remove polystyrene
– Open bag containing speaker
– Tape the carton flaps back
– Turn over carton with loudspeaker still inside
– Lift carton off, leaving loudspeaker standing on the
floor. You may now remove the polythene bag.

CHECK YOU HAVE:

Floor standing Evolution² speakers are supplied with a set of floor spikes. Invert the
loudspeaker and place the top on a soft
surface. Screw the spikes into the bushes
fitted in the base of the cabinet. Carefully
return the loudspeaker to its normal position. Adjust the height by screwing in or
out one or more of the spikes until the
loudspeaker is stable. For wood or soft
floors spike seats and self-adhesive pads
are provided.
WARNING: Floor standing speakers are
heavy - the spikes can penetrate softer
floors materials and damage wood and
stone floors over extended periods.

Specialist audio cable usually offers better performance than
general purpose ‘bell’ or ‘zip’ wire.
Choose a cable of suitable diameter – cable that is too thin
will limit the dynamics of the sound and may impair the bass
response. Audio cable is polarised, with two cores of different
colours, or often a raised rib of coloured tracer in the case of
twin cable.
Split the twin cores to a depth of about 40mm. Carefully strip
the insulation from each end, leaving about 10mm of bare
wire. If the cable is stranded, lightly twist to gather any loose
strands.

Crossover Networks

Evo loudspeakers use a specially designed bi-wireable crossover panel with four terminal binding posts. Please follow the
drawing carefully to see the correct orientation of the loudspeaker terminals. The upper terminals connect to the treble
unit and the lower pair to the bass units. As supplied, the treble terminal pair is connected to the bass terminal pair via
removable metal straps. These should be left in place for
standard single cable installations.

FITTING SPIKES (Evo-30,40,50)

Connecting Loudspeaker Terminals

Unscrew the terminal. Thread the bared end of each cable
through the hole in the bottom of the terminal post. Ensure
that there are no loose strands which may touch adjacent terminals. Retighten the terminal securely.
NOTE: When connecting loudspeakers, the cables to left and
right channels should be of equal length, regardless of the distance of the speakers from the amplifier.

For best results the speakers should be at
least 10 inches (20cm) in front of a wall
and at least 30 inches (70cm) from any
corner.

Angle speakers inward by 5º to 30º
for a clearer, more tuneful mid range.

Using separate cables for
treble and bass units in a
Bi-wiring configuration
reduces intermodulation
effects and improves
headroom and clarity. To
Bi-wire, you will need to
install two lengths of twin
core cable between the
amplifier and each loudspeaker.
Unscrew each terminal a
few turns and remove the
metal straps.
Connect the cables between
the amplifier and the loudspeakers as indicated and
re-tighten all the terminals
securely.
Note: Some amplifiers have
two pairs of output terminals to facilitate bi-wiring
but this is not essential.
The advantages of bi-wiring
are fully retained if your
amplifier has only one pair
of output terminals per
channel (as in the illustration).

Note that the wiring link bars are removed.
If the loudspeakers are placed too close to the walls the bass will increase but may
be boomy and indistinct. If the loudspeakers are placed further away from the
walls, the inward angle may be increased by upto 40%, although this may restrict
the width of the optimum listening position. As personal taste plays a large role,
experiment with different configurations and play a wide range of programme before
finalising the position of your speakers.

The Evolution signature SERIES
The Evolution Signature series is a range of versatile loudspeakers designed for
superlative reproduction in Stereo applications and as the Front loudspeakers in
no-compromise Home Cinema applications where they offer a performance
unsurpassed in their class.
These loudspeakers exhibit exceptional performance characteristics based upon
the following concepts.

Do not open the speakers; there are no
user serviceable parts inside.

Very low distortion across the entire audio band.
Low excursion requirement of the cone drivers.
High flux magnet systems enabling good dynamic response and impulse
control.
Broadband dispersion for excellent stereo image and staging.
Careful attention to component design, operation, integration and acoustics.
THE CABINET
The enclosure of your speaker is finished to a high-quality furniture standard.
Real wood walnut veneers are selected and carefully pattern matched by hand.
Over a period of several days a high quality hard lacquer finish is achieved. This
involves the application of several coatings of lacquers, each being cut and polished before the next coat is applied. Only through this time-consuming and
skilled technique, can we achieve the deep and lustrous finish that is the characteristic hallmark of Wharfedale premium loudspeakers.

Remove marks from the cabinet and
polish it with a soft, slightly damp cloth.

Instead of the usual cuboid shape, Evo loudspeaker cabinets feature a beautiful
curvaceous design, with a special purpose; - to reduce to negligible levels internal cabinet standing waves and reflections. Skilful engineering in ‘MDF’
(Medium Density Fibre Board), universally known to be one of the best enclosure materials, has resulted in an ideally shaped, very strong, internally multiple
braced, low resonance structure.
Parallel-sided tall boxes promote the creation of unwanted acoustic waveforms
within the box by reflection up and down its length; these both add and subtract
at different frequencies, creating anomalies in the forward response. The multiple curved and braced interior of the Evo cabinet prevents this - the result is a
soundstage of unexampled clarity and precision with pinpoint imaging, even frequency distribution and inherently low coloration.

THE DRIVE UNITS

THE BASS DRIVERS

THE 5Omm SOFT DOME MIDRANGE (Evo-50)

The bass driver(s) incorporates a new design of cone utilising our own Kevlar bi-weave process. Kevlar has immense
longitudinal strength and is used in many structures where high strength and light weight are key attributes. Kevlar can
be found liberally used in Formula 1 racing cars, aeroplanes, boats, spacecraft, skis and even golf clubs.
These fibre bundles are woven and impregnated with special bonding resins that are subsequently pressure formed
and heat cured. The resulting material is stiff, rigid and exhibits very low levels of internal resonance. Consequently,
energy losses in the cone transfer mechanism are very low.
Similarly, lateral voice coil strength is very high. We use a combination of half hard aluminium and resin bonded glass
fibre. This, in turn, contributes towards some of the lowest distortion figures ever seen in conventional drivers. The dust
cap/cover is of the same material as the cone.
The bass drivers operate only over the low frequency range. They are only used over their true pistonic range. The cone
is terminated with a conventional large half roll of synthetic butyl rubber with excellent inherent damping qualities.
A high performance traditional ferrite magnet system is used. Motional noise can be a problem with high output bass
systems. We address this by moving air through vents in the voice coil. The magnet system is also fully vented
throughout.
THE BASS MIDRANGE DRIVERS (Evo-30,40,50)
In any system featuring a cone bass/mid driver, performance and dispersion in the upper midrange band is critical, and
even more so when (as in our Evo 30 and 40 models) the midrange driver is crossing over to a dome tweeter,even one
with as wide and well maintained a response as our Evo dome tweeters.
By using a very low mass ultra stiff Kevlar cone in our bass/midrange drivers we provide virtually loss-less energy
transfer from the coil ensuring good impulse and dynamic response times. This, combined with a carefully developed
cone profile and a precisely shaped central coil cap projection, allows the higher bass and midrange frequencies to
provide not just extension but also wide dispersion at the bass unit's upper crossover point. The result is a seamless
crossover transition to the tweeter without the compromised off-axis performance usually associated with most 2 way
designs.

12
Evo SignatureV3A.indd 12-13

Derived from our flagship ‘Airedale Heritage’ loudspeaker, we have designed a series of dome mid-range
units which are exclusively used in our high-end loudspeaker products. Although costly to produce, the
benefits of a using a dome mid-range – particularly one with such as wide bandwidth as our own – are
lower distortion through this region, better integration throughout the frequency spectrum and an
extremely wide dispersion - all contributing to a very relaxed, natural presentation.
Because each driver in a multi-way system covers a smaller bandwidth, dynamic range and transient
response are hugely improved. Often this is at the cost of frequency integration but when our unique
dome technology is deployed, integration between upper and lower drive units is virtually seamless.
THE 25mm 1” SOFT DOME TWEETER
The highest frequencies are handled by a soft dome driver. Our extensive research has proven these are
a better choice than the metallic based domes that typically add their own character to the treble.
A feature of the tweeters, as with the mids, is wide dispersion and very low distortion, again typically
less than 1% at 100dB at 1 metre. The unit features a high flux neodymium magnet structure,
producing a typical efficiency of 93dB 1W@1m. This unit has a frequency response extending far
beyond audible frequencies to around 45kHz.
THE CROSSOVER AND WIRING
High quality OFC cable is used in each loudspeaker for internal wiring. High quality resin fibreglass
printed circuit boards are used throughout, and all connections are made to audiophile standards.
All inductors used are perfect layering wound and bonded and use large gauge wire for very low
insertion loss.
All capacitors used are either, low loss, low ERC polypropylene or high quality audio grade reversible
electrolytics.
