About the A.C.T. One Evolution
The Wilson Benesch A.C.T. One Evolution is a four-driver, 2.5-way floorstanding loudspeaker using in-house designed Tactic II mid/bass drivers with isotactic polypropylene cones and a Semisphere hybrid silk/carbon dome tweeter, derived from the company's Cardinal flagship design. Its design focuses on advanced cabinet engineering and materials, including carbon-fibre composite structures, to control resonances and optimise midrange performance rather than relying on overly complex crossover networks, yielding a full-range, 4-way acoustic behaviour in a compact enclosure. The A.C.T. One Evolution received a CES Innovation Award in 2017 and is manufactured in Sheffield, England.
