3-Way Foorstanding Speaker

A genuine example of luxury audio, ELYSIAN offers indulgence in design, materials, aesthetics and performance. A thorough and no-compromise approach has led the Wharfedale engineers to create a benchmark in affordable, audiophile-grade luxury loudspeakers. Cutting-edge design and class-leading technology are combined to deliver musical reproduction that will proudly challenge the world’s finest loudspeakers.

From the Piano-Lacquer finished cabinet, created with details of true craftsmanship, through to the AMT (Air Motion Transformer) high-frequency transducers and European manufactured bass drivers, ELYSIAN represents a new standard in the world of home audio experiences.

The resultant sound, from the finely balanced driver selection and expert crossover design, matches the pristine design with a degree of natural transparency that will leave you breathless.

ELYSIAN is truly an audio engineering work of art.

 

The AMT (Air Motion Transformer) is a radically different way of moving air. A large, pleated, lightweight diaphragm is driven across its surface by rows of strategically placed metallic strips immersed in a strong magnetic field. Under the influence of the musical drive the pleats in the diaphragm contract and expand, squeezing the air between them to form the desired waveform.

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. In addition, the AMT is a velocity, rather than pressure, transducer, capable of producing scintillatingly fast transients and dynamics. The result is a wide bandwidth device that achieves low distortion naturally and delivers wonderful musical detail.

In the spirit of Gilbert Briggs, who was well known for experimenting with new driver materials, Wharfedale investigated a range of options to match the sensitivity and accuracy of the AMT treble unit.

The designers settled on a proprietary woven glass fiber matrix, formed into a 150mm cone. This provides a superb combination of low mass and high strength, with the addition of a high-plasticity coating to control its acoustic behavior. With such a low-mass cone, only a low-damping, foamed, rubber-like material would match the surround – again, coated for durability.

Drive energy for the cone comes from a 25mm, 2-layer voice coil centered in a magnetic gap fitted with an aluminum ring to control eddy currents, linearize inductance and so increase bandwidth and reduce distortion. The whole assembly is fitted to a die-cast aluminum basket with large ventilation windows below the spider to improve transient response.

A central phase plug is specially shaped to linearize the output across a wide bandwidth, even off-axis, enhancing a natural response to the music which can be heard anywhere the listener wishes to sit.

This midrange driver enables the ELYSIAN speakers to deliver voices and instruments with astonishing realism. Vocalists seem to be present in the room with the listener – simply close your eyes and listen to the palpable presence of singers in the acoustic space.

The midrange unit is matched with a glass fiber matrix cone for the bass unit, in this case, terminated with a highly flexible rubber surround and driven by a specially developed low-distortion motor system. Mounted on a die-cast aluminum chassis, the magnet system features an aluminum ring for eddy current control, immersing the 17.5mm long, 38mm diameter voice coil in high flux over 12mm of linear excursion.

In order to plumb the depths of the lowest frequencies in recorded music, the 220mm bass units – one in the ELYSIAN 2, two in the ELYSIAN 4 are capable of reaching down below 28Hz in-room, revealing the full body and impact of percussion, stringed and wind instruments.
