OVERVIEW:

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 loudspeaker.

This revolutionary new drive unit topology, combined with the latest State-of-the-Art Wilson Benesch drive technology sets the design apart from the A.C.T. designs which precede it.

When distilled, the constituent parts of the A.C.T. One Evolution are a bold a statement of the expert engineering, manufacturing and craftsmanship that now pertains at Wilson Benesch. 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.

TECHNOLOGY:

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.

REVIEWS:

“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...

...I don’t want to get carried away by the bass. There is a lot more to this loudspeaker than bottom end. It’s just that the loudspeaker does bass so well, and so deep; that unbraced cabinet makes it TARDIS like and far bigger on the inside than you’d expect and that means more cabinet volume and that means more bass - but the level of control the A.C.T. One Evolution has over that bass is insane.”
