3-Way Stand-Mount/Bookshelf Loudspeakers with Air Motion Transformer Tweeters. Used as a Stereo Pair or with Larger Systems 3-Way Design AMT Tweeter (Air Motion Transformer) 2″ Soft Dome Mid-Range Tweeter (Woven Polyester) 6.5″ Woven Kevlar Woofer Bass Reflex Design (Rear Port) Recommended Amplifier Power: 25-120 watts Two Sets of Binding Post Speaker Terminals Allow Bi-Wiring and Bi-Amping Removable Magnetic Grilles The EVO4.2 is a 6.5″ High-Performance Bookshelf Speaker that sounds as good as it looks. Wharfedale’s new EVO4 has grown out of the extensive research and development that produced the ELYSIAN flagship loudspeakers and borrows much of the technology involved in ELYSIAN. The primary focus is on the Air Motion Transformer development resulting in a radically different way of reproducing high frequency detail efficiently and accurately. Similar cabinet technology to ELYSIAN provides a stable and solid foundation for the drive units with radiused edges to help integrate the driver output with the room acoustics. In addition the unique SLPP bass reflex system, as developed for ELYSIAN, is now incorporated in EVO4. EVO4 Series: The new EVO4 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, EVO4 represents the evolution of affordable high-fidelity audio. More than just a new edition, EVO4 also fuses the EVO concept with trickle down technology from the new flagship Wharfedale ELYSIAN series – and just like ELYSIAN, EVO4 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, EVO4 stands head and shoulders above the competition. Notably, the Wharfedale EVO4 series employs a specially engineered AMT (Air Motion Transformer) 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 stunning and sheer clarity of the musical performance of all of the EVO4 series loudspeakers. Application The EVO4 series is refined to appeal to the audiophile and the home-theatre enthusiast alike. Offering supreme performance in tight spaces, with the compact EVO4.1 and equally compact but 3-way design EVO4.3, there is also the option of the indulgent extension of bass, volume and impact in the 3-way 4.2 or 4.4. The 4C offers enhanced clarity of dialogue in home-cinema applications while the 4S surround speakers immerse the user in a genuine theatre experience. Whichever model is considered, EVO4 will exceed any expectation. Air Motion Technology The AMT (Air Motion Transformer) high frequency transducer excels above any rival model within this class. The point-source replicating, high volume air movement results in lower distortion and higher accuracy in HF reproduction. Woofers 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 found in the EVO4.2 upwards. Crossover 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. Design Taking strong elements from the Flagship ELYSIAN series, EVO4 has groundbreaking 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. The EVO4 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, for instance. All of this ensures the sonic character is not compromised by aesthetic. Quite the opposite, in fact.
