Available to demo in-store at Yorkshire AV - the new EVO4 from Wharfedale features many similar characteristics to the ELYSIAN but with added innovation on the AMT transducer to deliver an incredibly detailed and smooth high frequency reproduction as well as the unique SLPP bass reflex system.
A curved cabinet, attractive driver / hybrid tweeter design and premium finishes make this a very desirable set of speakers that carry both new tech and class in their presentation.
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 EVO4.3
EVO4 Dome Midrange
To match to the EVO4 AMT, Wharfedale has developed a fast and responsive dome midrange with wide bandwidth thanks to the incorporation of a damped rear chamber. This soft fabric dome, damped with a plasticizer coating, is vented aperiodically into a specially shaped rear chamber that is profiled to scatter and absorb rear energy from the dome. As a result this dome midrange features a linear response from 800Hz to 5kHz, an astonishing bandwidth from such a unit. Thanks to its high flux magnet, the EVO4 midrange dome also has a high efficiency, ideally matched to that of the AMT, enabling it to respond easily and quickly to the dynamics of the music fed to it. The wide dispersion of this dome and AMT combination ensures that you’ll hear all the musical detail no matter where you sit.
Utilizing the advanced, low distortion motor system developed for the ELYSIAN bass units, EVO4 marries this to a woven Kevlar cone fitted with a low loss rubber surround, giving a wide bandwidth driver which is equally adept at producing powerful bass in addition to a natural lower midrange quality. Like ELYSIAN, the bass units are loaded by the most advanced version of the unique Wharfedale Slot Port yet. Christened SLPP (Slot Loaded Profiled Port) the rear output of the bass units is not wasted. Instead the lowest frequency energy is vented to a slot at the base of the speaker, specially profiled to equalize the high internal pressure to the low pressure in the room.
Combining the outputs of the drivers is an advanced computer modeled crossover that has been developed over hundreds of hours of listening tests, fine tuned to make sure that the blend between the drive units is seamless. Crossover components have been specially chosen for their audio transparency and feature high-grade polypropylene capacitors and laminated silicon-iron and air core inductors, laid out to avoid electro-magnetic interference on a specially designed circuit board
