			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.
			

			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.
			
 
			
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.
			
		
		
			
			
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...
