The challenge of creating a loudspeaker that can match live music is twofold: first, grasp the auditory cues that communicate the brio of live music to the brain, and second, in the unfeeling realm of drivers, crossovers, and cabinets, know how to manipulate those materials to preserve the ineffable effect that music plays in our emotional lives.
In the case of Alexandria Series 2, the further challenge was to take a loudspeaker that had already, for many people, redefined the state of the art and elevate it to the next level of authentic value. The challenge was to move the marker forward an immediately recognizable degree.
The path to enlightenment always begins in the recognition there is more to learn. Dave Wilson unwittingly began the journey that led to the development of Alexandria Series 2 in Vienna, Austria – in a 19th century concert hall.
 
New Midrange Driver
For years, Wilson Audio, like many speaker companies, has sourced its drivers from outside, specialized manufacturers. These units have never been bought simply as off-the-shelf drop-ins. Once the raw drivers arrive at the Wilson factory, they've always been extensively modified, or, in some cases, essentially "re-manufactured" on site to Wilson's precise specifications and tolerances.
With this new driver, Dave and the Wilson design team, have, in strategic partnership with a new driver manufacturer, raised the performance bar in the critical midrange. To meet the design challenge of a highly rigid but low moving mass cone, we co-engineered a special blend of carbon fiber and paper pulp.
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 density and color and tone of musical instruments. Most importantly, because of its ability to start and stop instantaneously, it is capable of reproducing the subtle dynamic cues and low-level reflections that we recognize from live music.
 
New Tweeter
Subsequent to the introduction of the Series 1 Alexandria, Wilson Audio developed our most advanced tweeter for the MAXX Series 2 and later, the WATT/Puppy System 8. That design has now been further refined and improved for the Alexandria Series 2.
Once again, the overriding objective was to lower the noise floor, and thus increase low-level resolution, so that the new tweeter could play in the same league as the newly designed midrange. The primary culprit for tweeter noise is the unabsorbed reflections form the back wave. The Alexandria features a new damping material that effectively randomizes and disperses these reflections. The new design immediately lowered the output of the tweeter by 1.5 dB, the sum-total of which represented the noise component of the previous version.
A new milled sub assembly of X material provides a black, resonance-free background for the quietest, most grain-free tweeter in Wilson Audio's history.
New Crossover
It was inevitable that the lack of noise and distortion in the drivers would reveal the limitations of the crossover, so our anti-jitter technology has evolved to keep pace. The wider bandwidth of the midrange driver afforded not-wholly-unexpected benefits in the linearity of the bass, as those drivers were now relieved of some of their upper octave duties.
The new Alexandria raises the bar considerable for seamless integration of all the drivers through the new crossover design.
In all Wilson loudspeakers, the crossover assemblies themselves are wholly encased in epoxy, which serves two functions. One, it eliminates a possible source of electro-mechanical resonance, and two, it frankly preserves the proprietary nature of some of the technology which makes Wilson Audio Crossovers unique in the audio world. Nevertheless, the crossover panels of the new Alexandria are a point of pride, and are now easily accessible and visible through a new removable glass panel.
 
Adjustable Propagation Delay
A musical waveform is a complex overlay of frequencies, amplitudes, and phase relationships. With current technology, no single transducer can reproduce the full range of music at realistic sound pressure levels and maintain consistent dispersion. The only practical solution to this problem is a multiple driver array, but multiple drivers introduce their own set of problems, chief among them the challenge of preserving the precise time relationships of the musical waveform.
In conventional systems, drivers are mounted in a flat baffle such that each driver is positioned at a different distance in relation to the listener. Thus, energy from the tweeter arrives at the listening position in advance of the midrange, which in turn arrives before bass generated by the woofer. This problem of achieving both time-domain coherence and optimal driver dispersion is only exacerbated by larger speaker systems. The fact is, misalignment of the drivers by small fractions of an inch will audibly degrade transient performance, soundstage height, width, and depth, as well as introduce tonal anomalies that destroy the otherwise convincing “presence” of an instrument or a singer’s voice.
The key to solving this problem lies in the vertical alignment of the various drivers in an adjustable modular array so that each driver’s waveform propagation “matches up” with its neighbors’ in such a way as to create the sonic equivalent of a single point source. Wilson’s patented Adjustable Propagation Delay has long set the standard for precise driver positioning in order to ensure correct propagation alignment for a wide range of listening locations. Alexandria takes the technology a step further with its Aspherical Propagation Delay. Alexandria’s driver modules not only adjust forward and back (in the time domain), but also rotate on their vertical axis in order to achieve optimal driver dispersion for nearly any size room and for multiple listening positions. Alexandria is the only loudspeaker to utilize this unique innovation.
