The EVO 5 Series represents a bold step forward for Wharfedale – taking everything that makes the EVO4 a showroom-staple and multi-award winning loudspeaker series but blending luxurious design updates with technical evolution further to enhance the appeal of a price-bracket-defying loudspeaker offering.
Whether an audiophile seeking nuanced musical expression or a casual listener desiring clarity and depth, the EVO 5 speakers promise an immersive, high-fidelity experience that rivals far more expensive high-end audio offerings.

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.
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.
