Introduction • The Midrange •  Aspherical Propagation Delay • The Crossover •  Specifications

For years, Wilson Audio has worked with outside driver manufacturers, often co-designing custom drivers for a given application. While Wilson uses some drivers we have not had a direct hand in designing, in these instances, each unit is extensively modified, or, in some cases, essentially "re-manufactured" on site to Wilson's precise specifications and tolerances.

But when it came to designing a new midrange driver for the Alexandria Series 2, Wilson established a strategic partnership with a new driver manufacturer in order to co-engineer a proprietary unit from a fresh set of design parameters.

Because the midrange is arguably the heart and soul of music, we wanted the bandwidth of the driver to be as broad as possible so as to reveal the true tonal density and color of musical instruments. But perhaps even more important, the goal was to create a highly rigid and yet low mass cone that could start and stop instantaneously. Only a driver with these properties can reveal the subtle low-level dynamics and the earliest reflections of a live musical event. These are the cues that the brain recognizes as defining aspects of music's "realness", and it is precisely these cues that more conventional drivers smear and obscure.
