Wharfedale Surround Speaker EVO4S Black Oak (pair)

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 AMT 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. A long history of class-leading speaker concepts coupled with new technological breakthroughs means this is genuinely an evolution of affordable Hi-Fi.

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.

AMT

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.

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.
