Description

The Dawn of a New Standard

The Wharfedale EVO 4.2 has grown out of  the extensive R&D that produced the ELYSIAN flagship loudspeakers.  As a result, they borrow much of  the technology  involved in ELYSIAN. Primary focus is on the AMT development.  This results 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. The 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 AMT

Developed from the advanced AMT in ELYSIAN, EVO4’s Air Motion Transformer treble unit utilizes a radically different way of moving air compared to the conventional dome tweeter.  Rows of strategically placed magnets drive a large, pleated lightweight diaphragm. Not only is this an efficient way of moving air but it is also very accurate as the diaphragm is always under close control of the motor system.  The result is a wide bandwidth transducer that achieves low distortion naturally and delivers wonderful musical detail.

EVO4 Dome Midrange

To match to the EVO4 AMT,  Wharfedale has developed a fast and responsive dome midrange. It has wide bandwidth thanks to the incorporation of a damped rear chamber.  A plasticizer coating damps this soft fabric dome.  As a result, this dome midrange features a linear response from 800Hz to 5kHz. The result is astonishing bandwidth from such a unit. Thanks to its high flux magnet, the EVO4 midrange dome also has a high efficiency. The AMT ideally matches the midrange driver.  The midrange driver responds 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 when you listen to the Wharfedale EVO 4.2.

EVO4 Bass

Wharfedale EVO 4.2 utilizes 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. The result is 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 load by the most advanced  version of the unique Wharfedale Slot Port yet.  SLPP (Slot Loaded Profiled Port) is the name.  As a result, the bass units do not waste rear output.  Instead, the lowest frequency energy vents to a slot at the base of  the speaker.  The special profile equalizes the high internal pressure to the low pressure in the room.

EVO4 Crossover

An advanced computer modeled crossover combines the outputs of the drivers.  As a result, the crossover is fine-tuned to make sure that the blend between the drive units is seamless. audio transparency is the reason the Wharfedale EVO 4.2 crossover components have been specially chosen.  They feature high-grade polypropylene capacitors and laminated silicon-iron and air core inductors.  Consequently, they are laid out to avoid electro-magnetic interference on a specially designed circuit board.
