It is the largest of the shelf / rack mount models in Wharfedale's EVO4 range, defined by its creators as the dawn of a new standard of excellence in affordable Hi-Fi and representing the logical evolution of the celebrated EVO Series. With a 3-way bass-reflex configuration and 3 speakers, the EVO4.2 stands out not only for the refinements incorporated into its enclosure and the materials used in its construction, but, above all, for including an innovative tweeter based in the AMT operating principle ("Air Motion Transformer" or Air Motion Transformer). Due to the peculiarities of its design, the AMT transducer allows a greater volume of air to be displaced than a conventional dome tweeter from an extremely light diaphragm, resulting in a very precise, agile reproduction with less distortion of high frequencies. of the spectrum. Also the reproduction of the lower frequencies has received a great deal of attention in the design of the EVO4.2, as corroborated by the use of two woofers with a cone of woven Kevlar fibers of 165 mm, equipped with a characteristic dispersion modifier. in the form of a projectile. As a result, an extremely smooth acoustic cut-off is ensured, thereby further increasing the ability to integrate with the AMT tweeter and 50mm soft dome midrange driver. Another key aspect of the EVO4.2 is the careful design of the crossover filter, the development of which has involved hundreds of hours of listening combined with unique computer-aided optimization technology developed specifically for Wharfedale.
