This achievement is all the more remarkable given that Wilson’s proprietary M4 material,
first used in the Series 2 Alexandria, established the previous benchmark for midrange
performance.
Convergent Synergy™ Tweeter
The magic of Wilson’s midrange driver is in no small part due to its ability to cover
almost the entire mid-band without interruption of the crossover, including the male
vocal region. This always meant that the driver would be large, and therefore limited
in its upper frequency range. Wilson’s existing inverted titanium dome tweeter has long
proved a successful and coherent match to Wilson’s remarkable midrange driver. Dur-
ing its decade-long development, the current Wilson tweeter has evolved such that it
uniquely excels in the areas of low distortion, resolution of micro and macro dynamics,
and harmonic expression. Wilson’s current tweeter was developed to play down to the
one kilohertz region with low distortion and high power handling ability. Dave has been
willing to trade ultra-wide bandwidth for these more musically important characteristics.
Dave and the engineers have tested a very wide spectrum of tweeters utilizing
domes made from diamond, beryllium, and ceramic. Many of these exhibit flat frequency
response, and are extended into the octaves above the audible bandwidth. But none
matched the dynamic contrast and harmonic expression of Wilson’s current titanium de-
sign. And all have been unable to perform adequately with our midrange driver given its
unique demands.
Three years ago, Dave began a renewed quest for an improved tweeter that culmi-
nated in a proprietary Wilson design for the Alexandria. The result is the Wilson Conver-
gent Synergy Tweeter. The new Wilson tweeter rejects exotic materials in favor of a new
silk dome design that better meets all of Dave’s musical design goals.
The Convergent Synergy tweeter is a proprietary, Wilson-designed driver. With the
Convergent Synergy driver, Dave’s design requirement of ultra low distortion and very ro-
