Wilson Benesch One Evolution Speaker

Wilson Benesch, the British high performance loudspeaker designer and manufacturer, has announced the latest addition to its Geometry Series – the A.C.T. One Evolution, with the first set touching down in Australia this week.

The A.C.T One Evolution Speaker is now the new successor of Wilson Benesch’s legendary A.C.T Speakers, and is the result of two decades of research. Comprising a full range, 4-way acoustic, 2.5 way electrical, floor standing loudspeaker, the A.C.T One Evolution incorporates the latest drive unit and cabinet construction technology derived from the company’s Cardinal loudspeaker.

Standing at 1.2m (47”) in height, the A.C.T. One Evolution is a combination of precision-machined alloy baffle, alloy side panels and the Advanced Composite Technology ‘A.C.T.’ Monocoque. The A.C.T. Monocoque is a geometrically optimised carbon fibre composite structure that exhibits industry-leading resonance damping and signal-to-noise characteristics.

Each A.C.T. One Evolution is fitted with three Wilson Benesch Tactic II drive units and a Wilson Benesch Hybrid Dome Technology Semisphere Tweeter. Every element of the drive technologies and the cabinet of the A.C.T. One Evolution has been designed and developed using Wilson Benesch’s 3D Dassault CAD/CAM systems.

The degree of precision in the design of every component allowed ground up optimisation of the A.C.T. One Evolution, and has led to the development of unique drive unit topology and cabinet construction. In the midrange, Wilson Benesch introduces technology taken directly from the flagship Cardinal loudspeaker.

A two part cabinet construction sees a single 7” upper midrange Tactic II drive unit and Semisphere Tweeter operate in a volume-optimised enclosure, allowing acoustic roll off of the drive unit.

Directly below the Semisphere Tweeter in the main enclosure, is a 7” lower midrange Tactic II drive unit. By placing the Semisphere at the heart of the midrange, the A.C.T One Evolution Speaker is designed in a formation known as the Troika System. At the centre of the Troika System is the Hybrid Dome Technology Semisphere Tweeter, a highly engineered solution for high frequency sound reproduction.

The reduction in complex crossover elements translates directly into a highly articulate and natural midrange sound, and marks a significant advance in the performance of the A.C.T Evolution One’s midrange.

The hybrid dome is a direct departure from hard dome technologies now used as standard across the industry for wide bandwidth tweeter design. The natural sound produced by the Semisphere dovetails directly into the open sound of the midrange to create a highly integrated system, with stunning sound-staging and detail.

The A.C.T. One Evolution bass frequencies are delivered by a 7” Tactic II Bass Drive Unit. Like the midrange drive units, it features a powerful neodymium rare earth magnet encased in a motor assembly developed jointly with Sheffield University, in order to optimise flux across its geometry. This exotic magnet design is combined with a streamlined basket and a light, stiff isotactic polypropylene cone to create a powerful bass drive unit.

By installing the Tactic II Bass Drive Unit inside the 26 litre lower enclosure of the A.C.T. One Evolution, the system easily achieves the perfect combination of maximum dynamics, deep powerful bass frequency response and precision sound.

The A.C.T. One Evolution is a distinctive Wilson Benesch design. It's sculptured, curved and sloped top is a direct descendant of the original A.C.T.

Despite references to a classic design ancestry, the A.C.T. One Evolution is a clear descendant of other Geometry Series designs before it. Like the Cardinal and the Endeavour, the A.C.T One Evolution’s terminal is recessed on the underside of the foot, while upfront the baffle features the subtle machine finishing as seen in the Vertex and Vector loudspeakers. However, the Geometric cues are more than skin deep, and at the heart of the A.C.T. One Evolution are technologies that set this speaker apart and create a new Wilson Benesch loudspeaker of stunning pedigree.

The A.C.T One Evolution Speaker is available now for $43,900 RRP.

Wilson Benesch is distributed in Australia by Absolute Hi End.
