Wharfedale Aura 4

AURA 4 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.
