Alexandria XLF joins the Alexandria family, not as a replacement for the Series 2, but as its measurably more ambitious sibling.

While maintaining the recognizable Alexandria form factor, it is physically larger, with 14% greater bass volume. Thicker cabinet walls and added bracing for an even more inert enclosure.It introduces passive bass management technology unique in the audio world.

It introduces a new Convergent Synergy tweeter, a new crossover, and a host of parts all chosen through sedulous listening trials.

From the time he started building loudspeakers in his garage, Dave Wilson had one motivating passion: to make the reproduction of music sound as much like the real thing as possible. Although he is acutely aware of the limitations imposed on his dream by available driver technology, cabinet materials and the laws of physics, the goal remains the same. Dave is an idealist.

Tweeter technology evolved in the first decade of the new century, with new designs using exotic materials such as diamond and beryllium. Proponents of these designs extolled their ultra-wide bandwidth, in some cases extending to beyond 50 kHz. The engineering rationale was that pushing the tweeter's resonant frequency (or break-up mode) well above the audible spectrum would produce greater linearity within the audible range.

Dave Wilson and his engineering team began a three-year process of testing and evaluating new designs coming on the market. To match the demands of its standard-setting midrange, Wilson had already redesigned its titanium tweeter with great gains made in lowering the high-frequency noise floor. This was achieved primarily through enhanced control of back-wave reflections. At the same time, work on an all-new design began, borne of the desire to follow any path that would potentially lead to technologies that enhanced the consanguinity of Dave's speakers to the live event.

Their testing quickly revealed that tweeters able to play to 50kHz frequently did so by lowering the mass of their drivers. This, in turn, imposed at least two limitations on their performance. They failed to achieve the dynamic contrast required of a Wilson loudspeaker. Second, they couldn.t play low enough to cross over at the 1.2 kHz point demanded by the Wilson midrange driver. Most interestingly, none of the new exotic designs matched the dynamic contrast and harmonic expression of Wilson's existing titanium design.

Speaker Drivers Dave's frustration with off-the-shelf units led to the decision to design his own tweeter. The result of that effort is the Convergent Synergy tweeter. It maintains all the strengths of the existing Wilson driver: great dynamic contrast, harmonic expression, exceptional power handling, and low distortion. The Convergent Synergy is much flatter in its frequency response and has exemplary off-axis dispersion characteristics. With somewhat lower moving mass, it adds frequency extension to 33 kHz. As the name implies, these qualities converge with the advantages of the ultra-wide-bandwidth designs, with none of their sonic or technical disadvantages. It is an extremely synergistic companion to the Wilson midrange driver.

It.s easy to achieve flat frequency response in an anechoic chamber. But, in the real world, the sound of loudspeakers is highly dependent on the room they're in. Room-induced bass nonlinearities are a problem that has generated lots of solutions. One of the most common is active equalization, often processed in the digital domain. The downside is that insertion of an electronic equalizer into the audio signal produces deleterious audible effects in the rest of the frequency spectrum.

Wilson has always taken a purist approach to bass management, focusing on designs that inherently sound right in a wide range of rooms. Critical room placement by trained salespeople and installers has proved to be the most successful and efficient way to overcome most room-induced colorations.

With over 500 Alexandrias in use around the world, Dave observed that there were certain kinds of rooms in which the Alexandria X-2 could sound lean in the deep bass. This was often apparent in rooms with a lot of glass, and where the desired listening position was close to the center of the room.where a natural null zone exists for low frequency sound waves.

Dave conceived of the Cross Load Firing Port as an effective remedy for this room artifact. An elegantly simple idea, the (patent pending) Cross Load system allows the user to choose either a front or rear firing port configuration.

On the front of the XLF, below the woofers, is a distinctive brushed aluminum plate with the Alexandria XLF logo. In rooms where the rear-firing option will tend to overload the bass, it is simply a matter of removing the front plate and port plug, switching those items to the rear, and attaching the low-turbulence trim to the front, moving the port exit to the front of the Alexandria XLF.

Although the new loudspeaker retains the unmistakable form and lines of Alexandria Series 2 (seen on the left), the architecture of the XLF (on the right) has evolved to support new technology.

The Cross Load Firing port system (XLF) dictated a larger bass enclosure. It is 14% larger than the Series 2. The increased volume enabled the engineers to carefully shape the XLF.s bass response to be even more linear and room-friendly.

Using the latest analysis technology, Wilson.s mechanical engineers reworked the woofer cabinet, thickening the enclosure walls and redesigning the internal bracing geometry. Cabinet contribution in the bass region is extremely low in the Alexandria X-2. The Alexandria XLF is even more inert.

Wilson has a long tradition of cross populating advancements from one design to the rest of the line. This sometimes means that a more expensive model benefits from technology introduced in a less expensive loudspeaker. First introduced in Wilson's venerable WATT/Puppy replacement, the Sasha W/P, S-material is a highly rigid, critically damped, epoxy-based composite. It was developed specifically for midrange beauty and ultra-low resonance. In combination with X-material, S-material reduces measurable and audible noise and coloration in the midrange.

Without question, Alexandria XLF is the most complex loudspeaker Wilson Audio has ever produced. According to mechanical engineer, Blake Schmutz, CNC milling the pieces for an XLF requires an entire week of eight hour shifts just to complete one channel.
