About The Wharfedale EVO4.S Speakers
There are surround speakers and then there are the Wharfedale EVO 4.S Surround Speakers. These are so well made and sound so clear and spacious that they make most run of the mill surround speakers seem like a joke. Superbly styled and constructed, the EVO 4.S are available in a choice of three fine finishes - White Oak, Walnut or Black.
The EVO 4.S uses the same advanced driver technology as the rest of the range and features two Air Motion Transformer tweeters, two 50mm (2") soft dome midrange drivers and a 165mm (6.5") woven Kevlar bass driver. The drivers are placed in the carefully shaped cabinet to give the most spacious sound possible and this they do extremely well. Additionally there is a clarity and depth to the sound that will bring your cinema experience to life. Naturally the EVO 4.S is voiced to perfectly complement other members of the Wharfedale EVO 4 family but their quality is such that they could easily be used with more expensive options if required.
The Evolution Of Sound
The new EVO 4 range represents the dawn of a new standard in Hi-Fi, from Wharfedale – the most famous name in British loudspeakers. Following the concept of the best-selling Evo series that came before it, EVO 4 represents the evolution of affordable high-fidelity audio. More than just a new edition, Evo 4 also fuses the Evo concept with trickle down technology from the flagship Wharfedale Elysian series – and just like Elysian, EVO 4 pushes the boundaries of technology and performance of speakers within this price class. From the cabinet design to the materials employed in its distinct design, EVO 4 stands head and shoulders above the competition.
Notably, the Wharfedale EVO 4 series employs a specially engineered AMT (Air Motion Transformer) treble transducer for its proprietary, silky smooth high frequency reproduction. By design, the AMT allows for a higher volume of air to be moved during performance than with a convention soft dome tweeter. This higher-pressure action, encouraged by the principles of AMT design, offers an improved point-source HF reproduction with lower distortion properties than conventional tweeters. This is evident in the sheer clarity of the musical performance of all of the EVO 4 series loudspeakers.
Evolution By Design: Taking strong elements from the Flagship Elysian series, Evo 4 has ground breaking research and design embedded in its DNA. A long history of class-leading speaker concepts coupled with new technological breakthroughs means this is genuinely an evolution of affordable Hi-Fi.
Beauty With Purpose: The EVO 4 cabinet is purpose-designed from the ground-up. Not just the sleek curves, which stand out from the competition, but the materials, composites, internal bracing and damping too. All of this ensures the sonic character is not compromised by aesthetics. Quite the opposite, in fact.
Air Motion Transformer Tweeter: The AMT (Air Motion Transformer) is a radically different way of moving air. A large, pleated, lightweight diaphragm is driven across its surface by rows of strategically placed metallic strips immersed in a strong magnetic field. Under the influence of the musical drive the pleats in the diaphragm contract and expand, squeezing the air between them to form the desired waveform. Not only is this an efficient way of moving air but it is also very accurate as the diaphragm is under close control of the motor system at all times. In addition the AMT is a velocity, rather than pressure, transducer, capable of producing scintillatingly fast transients and dynamics. The result is a wide bandwidth device that achieves low distortion naturally and delivers wonderful musical detail.
Accuracy: Articulate and accurate bass is perfected by the bi-directional weaved Kevlar cones – a material that is naturally self-damping to reduce and distribute resonances to virtually negligible levels. In addition, a fixed, profiled phase plug ensures smooth acoustic roll off, further aiding integration with the AMT HF unit and mid-range drivers.
Finely Tuned: As per the uncompromising workflow and standard of Wharfedale loudspeaker development, hundreds of hours of listening plus custom designed Wharfedale Computer Aided Optimisation technology allows for the fine tuning of the crossover, perfecting the combination of the driver selection for ultimate performance.
Versatile In Application: The EVO 4 series is refined to appeal to the audiophile and the home-theatre enthusiast alike. Offering supreme performance in tight spaces, with the compact Evo 4.1 and equally compact but 3-way design Evo 4.3, there is also the option of the indulgent extension of bass, volume and impact in the 3-way 4.2 or 4.3. The 4.C offers enhanced clarity of dialogue in home-cinema applications while the 4.S surround speakers immerse the user in a genuine theatre experience. Whichever model is considered, Evo 4 will exceed any expectation.
