The name A.C.T. is an acronym for ‘Advanced Composite

Technology’ - it is a reference to the carbon fibre composite

technologies upon which the Wilson Benesch brand was founded and subsequently has become synonymous with. The A.C.T.

acronym was used when naming the companies first loudspeaker the A.C.T. One in 1991 and appeared subsequently in the A.C.T.

Two, A.C.T. and A.C.T. C60 loudspeakers.


The A.C.T. One Evolution therefore follows a long line of speakers, embodying the heritage of the Wilson Benesch brand and a now

classic A.C.T. design. The characteristic sloping, curved A.C.T. top

that was revolutionary in the original design remains, but like the C60 before it, the top is now manufactured from carbon fibre.

Similar physical proportions have been retained, however the

A.C.T. One Evolution has departed entirely from the traditional

drive unit topology used in the previous iterations of the design.

The new A.C.T. One Evolution incorporates the Troika System

which has been taken directly from the flagship Cardinal



The A.C.T. One Evolution is a full range, 4-way acoustical, 2.5-way

electrical, floor standing loudspeaker that incorporates the latest drive unit and cabinet construction technology derived from the

company’s engineering masterpiece, the Cardinal loudspeaker.


Taken as a whole, the A.C.T. One Evolution — with its

characteristic foot design, drive technology and alloy baffle — is a pure Geometry Series thoroughbred.


“The A.C.T. One Evolution is the distillation of all the engineering

and materials science development that Wilson Benesch can

throw at a loudspeaker… where the original A.C.T. One began

‘tabula rasa’, the A.C.T. One Evolution draws upon drive unit

technology and high compression cabinet construction  derived

from two decades of loudspeaker design...
