Grown out of the extensive research and development that produced the ELYSIAN, Wharfedale have introduced the EVO4 series, which borrows much of the technology involved in ELYSIAN.
The Wharfedale Evo 4.1 Standmount Speakers are a compact home speaker with good bass response and the Air Motion Transformer treble technology.
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.
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.
A large, pleated lightweight diaphragm is driven across its surface by rows of strategically placed magnets. Not only is this an efficient way of moving air but it is also very accurate as the diaphragm is under close control of the motor system at all times. The result is a wide bandwidth transducer that achieves low distortion naturally and delivers wonderful musical detail.
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.
