The AMT diaphragm is also operating over a large area, for advanced efficiency,
and is able to generate transient acoustic power quite easily. Wharfedale's design
team have improved the AMT unit in AURA loudspeakers to extend the response to
36kHz (-6dB) allowing a smooth and linear response to 22kHz (+-3dB). The
result is exceptional clarity of treble detail allied to realistic transient response,
smoothly enhancing the harmonic overtones of voices and instruments whilst

designing the Elysian series, the transient
accuracy and efficiency of the AMT needs to be
matched by the midrange and bass drivers for
a seamless audio performance. Accordingly,

a
glass-fibre matrix diaphragm for the midrange
and bass cones terminated by high flexibility
rubber surrounds. The voice coils driving the
cones are immersed in high-flux magnetic
fields, with eddy currents and inductance
controlled by Copper-clad pole pieces.
These low-distortion motor systems are mounted on die-cast aluminium chassis,
each fixed to the cabinet by six high-tensile bolts to maintain the rigidity of
structure and provide accurate transient response.
surrounding each chassis are not just a cosmetic feature but also control any
resonance occurring at the junction of the aluminium chassis and wood cabinet.
