Wilson Benesch Isobaric Drive System.

Wilson Benesch writes: “The new A.C.T. 3zero features an Isobaric Drive System in its foot. The Isobaric Drive System delivers powerful bass through a push-pull design with two Tactic 3.0 drive units in a clamshell formation. The design ensures that the bass woofers are perfectly integrated with the midrange woofer.”   

“Which in part is what makes a Wilson Benesch sound so natural, lifelike and engaging. Timing in music is everything and therefore integration in loudspeaker design is fidelity.”
