Reference Standard Super Linear Adjustable Monitor
Alexandria is the fruition of a blank-slate approach to creating a new flagship loudspeaker for the real world. It introduces radically new technologies, such as Aspherical Group Delay, and capitalizes on the synergistic application of technologies perfected in the decade since the X-1 platform was introduced. The design goal was to extend the musical beauty achieved by MAXXŽ, the WATT/PuppyŽ System, and SophiaŽ into a system of unprecedented dynamic impact and resolution.
Alexandrias revolutionary Aspherical Group Delay employs upper frequency driver modules that adjust linearly to optimize time alignment. Additionally, each module also rotates on its polar axis in order to achieve optimal driver dispersion for nearly any size room and for multiple listening positions. Alexandria is the only speaker on the planet capable of this refinement.
Form, Function & Fanatacism
One of the great design principles of the past century holds that the greater the harmony between an object's function and the form it takes, the greater its inherent beauty. For example, the deep lustere of the automotive paint finish on Wilson products wouldn't be possible without the rigidity of the underlying cabinet material.
Most manufacturers use MDF (Medium Density Fiberboard) for the construction of their enclosures. A few tout the use of exotic (and endangered) hardwoods for their cabinet finishes, yet wood is an acoustically resonant material. The incomparable sound of a Stradivarius or Guarnerius is due largely to the resonance of the wood and glues those craftsmen used. In order to realistically reproduce the sound of a Stradivarius, however, the objective must be to create highly accurate transducers, join them via seamless crossovers, align them unerringly in the time and phase domain, and enclose them in a cabinet which introduces absolutely no coloration of its own.
The fanaticism with which Wilson Audio pursues each of these objectives is simply without parallel in the audio industry. We've even developed proprietary adhesives to bond our enclosures, each designed for a specific material, and tested for permanence in the harshest climates.
New Cabinet Geometries
New combinations of M and X material in the three top modules. For the first time, X material is used exclusively in the tweeter module. The two midrange modules utilize new combinations of X and M materials, resulting in the most inert enclosures yet produced.
New cabinet geometries independently engineered for each module. This greatly reduces driver to cabinet interaction, nearly eliminating all cabinet colorations.
Aspherical Propagation Delay
Alexandria's revolutionary Aspherical Propagation Delay features driver modules that not only adjust forward and back (in the time domain), but also rotate on their polar axis in order to achieve optimal driver dispersion in nearly any size room and for multiple listening positions. X-2 is the only speaker on the planet capable of this refinement.
Aspherical Propagation Delay is just one of the X-2' s unsubtle achievements which led Robert Harley of The Absolute Soundon the basis of a mere 90 minute auditionto award Alexandria a 2003 Golden Ear Award. He proclaimed:"...those 90 minutes strongly suggest that the X-2 is not only a breakthrough product for Wilson Audio, but a landmark achievement in loudspeaker design."
