There are 14 separate elements in one W.B. One Dynamic drive unit.
Each element has a direct effect upon the sound that the final sub system will make. When each component is under your control it is possible to guarantee that each hand made drive unit is manufactured to standards that may appear to be above and beyond what is reasonable. What is more, because the unit is made under the same roof that it was designed, the most fastidious attention to detail is possible as is evolutionary progress as in the case of the W.B. One.
It should not be forgotten that Wilson Benesch drive units are often presented in their full glory to be seen in every detail. This is not done for aesthetic but acoustic reasons. What is described below is the process required to realise just one front plate. One component part of the W.B. One dynamic drive unit.

The latest advanced developments in driver technology to come from Wilson Benesch is the W.B. ONE.
As part of our on going research we are delighted to be able to announce the results of extensive evolutionary development. The W.B. ONE builds upon the strengths of the Tactic drive unit, retaining as it does the same cone technology and the lowest structural profile basket system in the world. The design has been created to form part of Trinity, where improved transient response is a major design objective. The mounting arrangement is totally different to previous designs and so it is not possible to provide this unit as an upgrade solution.
There is not enough space here, to cover all the details of this important component. A White Paper will be posted in the autumn. The main objective of the new motor design was to deliver as much valuable flux to the gap as possible. Another important goal was to make small but important improvements to air flow within the system itself that acts against the dynamics of the moving elements. The outcome is a more powerful system that sees optimised venting of air. The spring effect of constrained air has been almost eliminated and as a result a 2dB improvement in S.P.L. smoother response in the roll off region and improved dynamic control has been realised. Significantly this has been achieved with minimal increase in the motor structure, an important virtue of the Tactic drive unit. Each individual part is precision machined by Wilson Benesch to exacting tolerances. These tolerances are simply beyond the scope of drop forged, conventional designs.
