Wharfedale Aura 2

AURA 2 AURA is the latest innovation in the family of class-leading Wharfedale speakers. Taking inspiration from the flagship ELYSIAN series through fit, finish and technological derivatives, AURA is another boundary-breaking model that challenges the norms of value while delivering all the detail, energy and thrill of your music collection with a class-leading performance but with a class-defying price tag. AURA AMT Equipped with the now world-famous Wharfedale AMT transducer, each AURA model emits breathtaking high-frequency definition. Unlike conventional dome or other ribbon and planar diaphragms, the Wharfedale AMT high-frequency transducer does not move forwards and backwards like a piston. It is, therefore, not constrained by the mass of its diaphragm, with the attendant blurring of transient response. Instead, the diaphragm is folded and carries conductive elements immersed in an immensely strong magnetic field. Not only is this an efficient way of moving air, but it is also highly accurate as the diaphragm is under close control of the motor system at all times. The result is a wide bandwidth transducer that achieves extremely low distortion and extraordinary musical detail, with scintillating speed and dynamic ability. AURA Cones As Wharfedale engineers found when designing the flagship ELYSIAN series, the transient accuracy and efficiency of the AMT need to be matched by the midrange and bass drivers for a seamless audio performance. Accordingly, AURA also uses a proprietary woven 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 the structure and provide an accurate transient response. The rubber trim rings surrounding each chassis are not just a decorative feature but also control any resonance occurring at the junction of the aluminium chassis and wood cabinet.
