Class-leading Innovation.
Stunning Realism.
Founded in 1932, Wharfedale’s founder, Gilbert Briggs, had one goal in mind to bring music into the home by designing loudspeakers that conveyed the impact, thrill and emotion of performance in an entirely natural and realistic way.
Thus he created the first true hi-fi experience for connoisseurs of music in the home and continued to introduce technology that would enhance the listening experience like the first commercial crossover, foam surrounds and the slot port system Today Wharfedale engineers follow the same dictum utilising technology where it truly matters to develop loudspeakers that reveal the passion and excitement behind the musical performance.
AURA is the latest innovation in the family of class-leading Wharfedale speakers.
Taking inspiration from the flagship ELYSIAN series, by way of fit, finish and technological derivatives, AURA is another boundary-breaking model that challenges the norms of value while delivering all the detail, energy and thrill of your music collection.
Designed & engineered  in the United Kingdom

Designer’s Notes

AURA continues the wharfedale tradition of offering exceptional performance and value for money with a range of speakers that offer the home listener and dedicated audiophile a combination of monitor-class audio transparency together with class-leading Levels of musieal enjoyment.
Borrowing heavily from the advanced technology of the elite Elysian research project, AURA features the Wharfedale AMT high-frequency transducer, glass fibre matrix widrange and bass cones, the SLPP port system and multi-layer cabinets.

Wharfedale AMT High Frequency Transducer

Unlike conventional dome or other ribbon and planar diaphragms, the Wharfedale AMT high-frequency transducer does not move forwards and backwards like a piston. It is therefore not constrained by the mass of its diaphragm, with the attendant blurring of transient response. Instead the diaphragm is folded and carries conductive elements immersed in an immensely strong magnetic field. When the music signal from the amplifier traverses the diaphragm, the foldsconstrict and expand. This has the effect of squeezing the air between the folds, rapidly altering its pressure to accurately transmit the equivalent pressure wave received by the microphone(s) in the recording studio. The AMT diaphragm is also operating over a large area, for advanced efficiency, and is able to generate transient acoustic power quite easily. Wharfedale’s design team have improved the AMT unit in AURA loudspeakers to extend the response to 36kHz (-6dB) allowing a smooth and linear response to 22kHz (+-3dB). Theresult is exceptional clarity of treble detail allied to realistic transient response, smoothly enhancing the harmonic overtones of voices and instruments whilst providing shimmering realism to percussion such as cymbals. 

Glass Fibre Matrix cones

As Wharfedale engineers found when designing the Elysian series, the transient accuracy and efficiency of the AMT needs to be matched by the midrange and bass drivers for a seamless audio performance. Accordingly, AURA also uses a proprietary woven glass-fibre matrix diaphragm for the midrange and bass cones terminated by high flexibility rubber surrounds. The voice coils driving the cones are immersed in high-flux magnetic fields, with eddy currents and inductance controlled by Copper-clad pole pieces.
These low-distortion motor systems are mounted on die-cast aluminium chassis, each fixed to the cabinet by six high-tensile bolts to maintain the rigidity of structure and provide accurate transient response. The rubber trim rings surrounding each chassis are not just a cosmetic feature but also control any resonance occurring at the junction of the aluminium chassis and wood cabinet. Multi-layer lacquered cabinet
AURA cabinets are, in many ways, a work of art. Available in Black, White and a feature grained Walnut real wood veneer, each cabinet is lacquered and polished to present a beautifulpiece of furniture you will be proud to have in your home. The smooth curves to the cabinet are more than just eye catching. They help to disperse the acoustic output of the drive units smoothly into the room without undesirable reflections from otherwise sharp edges.
Underneath the polished lacquers lie cabinet walls built from multiple layers of differing woods designed to reduce panel resonance below audibility. This multi-layer construction, PROS (Panel Resonance Optimization System) has afurther benefit – it inhibits the leakage of unwanted sound energy from inside the cabinet which would otherwise interfere with the forward output of the drive units.
Already, much of this internal sound energy is absorbed by multiple layers of matted long hair fibre – its damping factor specifically calculated to avoid rear reflection back out through the drive unit cones whilst still allowing unrestricted airflow to the SLPP reflex port system. SLPP Reflext Design
Wharfedale’s SLPP (Slot Loaded Profiled Port) bass reflex design was developed from an original idea of Gilbert Briggs, the entrepreneur who set up and ran Wharfedale from 1932 to 1964. In AURA loudspeakers, the high-pressure, high-velocity airflow from a downward-facing port is better matched to the low air pressure in the room by distributing the airflow through a series of slot ports in the plinth. This both reduces unwanted turbulence from the port and also improves the efficiency of the bass reflex system.  AURA Crossover
In conjunction with the low resonance of the bass units, the SLPP system provides bass extension to well down into and below the 30Hz region for AURA 2, 3 and 4, revealing the fundamentals of most musical instruments with excellent articulation, clarity and power. You can feel as well as hear the true acoustic power of the musical performance.
In many ways the crossover is the ‘heart’ of every loudspeaker. Wharfedale were one of the first domestic speaker manufacturers to utilise a crossover to divide the frequency band between drive units that were optimised for bass, midrange and treble.
But today’s crossovers have to do more than just divide up the musical input to the loudspeaker and distribute it to the relevant drive units. The crossover also has to be matched accurately to the acoustic performance of each drive unit to achieve a blend between the drivers that is acoustically seamless. Although this process is aided by the sophisticated computer analysis available from measurements made by Wharfedale’s engineers, the fine- tuning has to be done by ear using a variety of musical sources and styles. In addition each crossover component has to be tested and evaluated for its acoustic transparency. Bass and midrange/treble crossovers are laid out on separate PCBs in order to reduce electromagnetic interference and coupled to their respective terminals to allow bi-wiring if required.In fact this crossover fine- tuning can take hundreds of hours of listening and testing in  order not only to provide a seamless blend butalso to balance the fundamental and harmonic overtones of voices and instrumentsso that they sound stunningly realistic whenreplayed in the home. The result is that, when you close your eyes, the AURA speakers seem to disappear and you are simply enfolded in the musical experience. In 1979, Peter Comeau co-founded Heybrook Hi-Fi to design and manufacture the multi-award-winning HB1 and classic HB2 loudspeakers. In 2009, after leading IAG speaker development since the acquisition of Mission, Peter assumed overall acoustic design responsibility for all of the brands within the Group, including Wharfedale. With a deep respect for the history of these brands and the necessity to maintain each individual brand’s design integrity, Peter continues to design award-winning speakers at IAG’s research centres in Huntingdon, England, and Shenzhen, China.

Loudspeaker Installation

Unpacking Your Loudspeakers

• Please read this manual as soon as you have opened the carton.
• Lift the loudspeaker carefully out of the packing. Do NOT try to lift the loudspeaker using the cloth bag.
• Unpack any accessories carefully.
• If there is any sign of damage or if the contents are incomplete, report this to your dealer as soon as possible.
• Retain the packing for future safe transport of the product. Dispose of the packing with respect to any recycling provisions in your area.

Attaching the Spikes to Floorstanding Model

• Make sure you have plenty of unobstructed working space and assistance for lifing and moving the speaker.
•  Place a soft cloth or protective material on the floor to protect the loudspeaker.
• Invert the loudspeaker onto the cloth or protective surface.
• Thread a locknut onto each spike and loosely fix it up the thread
• Thread the spikes into the spike inserts. Tighten them by hand until tight (do not use mechanical or power assisted tools for tightening)
• Invert the loudspeaker to the upright position. Be careful not to damage the floor with the spikes.

Levelling the Loudspeakers

• When the speaker is upright, with the spikes on the floor, you may find that the speaker is not completely level and/or one spike is not in full contact with the floor.
• In this instance; simply adjust the spikes by loosening or tightening as required Spike seats are included in the accessories box for use with AURA 4 / AURA 3 feet, or corresponding AURA standmount speaker stands.
• Spike seats are for use on wood or stone floors etc. Simply place these underneath each spike to isolate the spike from the floor.
• When you are satisfied the spikes are adjusted correctly and the loudspeaker is stable on the floor, tighten the lock nuts

Looking After Your Loudspeaker

• This speaker is hand-finished with a genuine Piano-Lacquer. As with all real wood furniture finishes; exposure to direct sunlight, heat, cold and varying humidity can affect the natural properties of the speaker cabinet. We advise protecting the speaker from extreme variances in temperature and environment conditions.
• We advise that you do not place anything on the surface of the cabinets, to protect from damage. Treated with care, the genuine Piano-Lacquer finish will last a lifetime. They will age naturally and subtly, retaining the properties of the beautiful high gloss finish.
• Your Wharfedale loudspeakers use a specially hardwearing sealed finish. They should not be waxed or treated with spray polishes which will smear and dim their lustrous finish
• Polish them with a dry or barely moist cloth to remove dust and finger marks, etc.
• Occasionally, remove the loudspeaker grilles and brush them gently with a soft brush before replacing them carefully.
• Avoid getting any liquid behind the grille. If you accidentally spill liquid on your loudspeakers, take them to your dealer for attention before using them again.

Standard Connection

• Connect the supplied link cables (from the accessories box) to the terminals of the loudspeaker.
• Choose a suitable length of twin core speaker cable for each channel and prepare the ends. Unscrew each terminal a few turns. Connect the red positive (+) terminal of the Left negative (-) terminals similarly. Tighten the terminal securely.
• Repeat this procedure for the Right Channel. If you are standard wiring make sure the terminal links are securely in place.

Bi-Wiring Connection
Unscrew each terminal a few turns. Connect the cables between the amplifier and the loudspeakers as indicated above and re-tighten all the terminals securely
Positioning Stereo Loudspeakers

• If you are sitting within 2m of the speakers, the distance between the speakers should be the same as between you and the speakers.
• Otherwise site the speakers between 2 to 4 metres apart, clear of rear walls and room corners.
• 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 (“toe in”) may be increased by up to 30%. As personal taste and room
• The optimum listening position is in an area between the speakers broadly known as the “sweet spot”. The more extreme the angle of toe-in the narrower the sweet spot. Wharfedale loudspeakers are designed to cover a wide sonic perspective so there should be no need for extreme settings. A mild angle inwards will cover a wide range of seating positions.
• The grilles are provided to protect the loudspeaker drive units from accidental damage. For critical listening, please remove the grilles.

SettingUp a Home Theatre System

• Front and Effects Channels: The front loudspeakers are placed on either side of the television screen, 2 to 3 metres apart. The speakers should be angled slightly so they are aimed towards listeners. We recommend placing the rear effects speakers in a high
  position, behind the listener’s head. the rear or side walls are a long way from the listening seat, consider stand mounting the loudspeakers. If the centre loudspeaker is very high or low, angle it towards the listener’s ear level

• The front faces of the centre and surround loudspeakers should also be in line as far as possibls.

• Subwoofer: As the ear is unable to detect the direction from which deep bass originates, you have freedom to position the unit. Varying the distance from the wall alters the bass. Placing the subwoofer across a corner boosts the bass but may impair clarity. The performance of a home theatre system can be enhanced by using two subwoofers.

61and 7.1 System Placement

• Dolby Labs, DTS and THX offer 6.1 and 7.1 format. Although the precise configuration of these systems will depend on the capabilities of your processor and you should be guided by those instructions, we would make some observation
•  For 6.1 and 7.1 formats the listening seat should not be too close to the rear wall
• Optimising the time delay so that information from all speakers arrives the listening seat coherently is critical of the benefits of these systemsare to be fully realised.
• Dolby Labs Recommended Placement for Multichannel Home Theater Systems,
