EVO 5.2
High Frequency Unit
The EVO series concept originated from the same thorough research and development processes that characterised Wharfedale’s flagship Elysian project. It was specifically designed to bridge the gap between affordability and high-end performance. A notable feature of this series is the EVO AMT (Air Motion Transformer) high-frequency unit.
A Distinctive Approach to High Frequencies
AMT Tweeter for Precision and Detail: In developing the new EVO 5 series, Wharfedale has further evolved the cutting-edge Air Motion Transformer (AMT). The AMT is a type of high-frequency driver used in speakers, known for its exceptional accuracy, speed, and low distortion compared to traditional dome treble units.
Instead of using a conventional dome or cone to push air forward, an AMT uses a pleated diaphragm made of an ultra-thin, lightweight material (often a polymer film). Strong magnets are positioned on either side of the diaphragm, creating a powerful magnetic field. When an audio signal is passed through the conductive traces, the diaphragm is energised, causing the pleats to contract and expand. As the pleats move, they "squeeze" and "expand" the air between them, pushing it out in a highly controlled and eficient manner. This method allows the AMT to move four times more air than a traditional dome tweeter of the same surface area, leading to lower distortion (since the diaphragm moves less than a typical dome or ribbon), faster transient response (due to the lightweight material and minimal movement), wider frequency range and better dispersion.
The EVO 5 AMT goes further with Revolutionary Sound
Absorption and Damping Enhancements
A new sound-absorbing material, Silentweave™, has been added to the cavity behind the diaphragm to reduce sound wave reflection and sound colouration inside the speaker. This material, a combination of cotton and felt fibre, was specially developed for the EVO 5 series.
All EVO 5 drive units benefit from a new acoustic damping frame called ResoFrame™, made from elastomer and visible as a cog-like shape within the driver’s front panel. In the case of the AMT, an additional elastomer damping gasket between the diaphragm and the front plate further reduces mechanical resonances and smooths the response, especially in the important lower treble band.
These Internal Acoustic enhancements minimize unwanted sound coloration, ensuring a purer, more natural sonic signature. This smoother treble response delivers a listening experience that is crisp, controlled, and devoid of harshness.
Lower-Midrange and Bass Refinements for Unparalleled Vocal Reproduction
Enhanced Midrange: A new technique, labelled Resoseal™, sees a thin mass ring of elastomer applied to the rear of the cone where it meets the surround. This further optimises midrange frequency response, allowing vocals to sound richer, more naturaLower-Midrange and Bass Refinements for Unparalleled Vocal Reproductionl, and more emotionally engaging. This subtle yet critical enhancement ensures a refined and immersive listening experience.
Reengineered Cabinetry for Superior Resonance Control
Each model in the EVO 5 series now features an optimally increased internal cabinet volume. The expanded cabinet volume contributes to deeper bass extension and improved overall sound dispersion, creating a more immersive and expansive audio field.
The inclusion of a hybrid plinth, which combines metal and wood elements of the cabinet’s details, enhances structural integrity and reduces unwanted vibrations. This innovative base ensures that sound remains clean and uncoloured, free from external resonance artefacts.
EVO 5 Stands
For the EVO 5.1 and EVO 5.2 loudspeakers, specially designed stands are offered to ensure the perfect synergy between form and function. Crafted from high-carbon steel, these stands provide exceptional strength and stability while effectively minimising unwanted vibrations and interactions with floor surfaces that could compromise sound quality.
Engineered with precision, they position the loudspeakers at the ideal listening height, ensuring an immersive and well-balanced audio experience across various seating positions. Their understated yet elegant design seamlessly complements the aesthetic of the EVO 5 series, maintaining the refined and sophisticated appeal of the speakers themselves.
