Tweeter
Daryl Wilson and Wilson’s team of engineers recently concluded another round of research and development into tweeter technology. The research included tweeter domes constructed of diamond and beryllium. After exhaustive testing and listening, Wilson’s engineering team concluded that the silk-dome Convergent Synergy Tweeter remains the most musically authentic and emotionally satisfying tweeter yet tested. Wilson’s unique holistic approach to design was at play here—employing a combination of carefully conducted measurements and empirical listening. The Wilson-designed Convergent Synergy was further and specifically evolved and developed for the Master Chronosonic, and is designated as the Mark V version.
Woofers
Unlike the original WAMM, which required a subwoofer to cover the bottom octaves, the Master Chronosonic is a true full-range design. In order to achieve Dave’s design goals, it was decided that an all-new approach in the area of bass drivers was needed. The design imperative was to maximize transient integrity, speed, and bottom-octave extension. The all-new 10.5 and 12.5 inch woofers were designed from the ground up to complement each other, specifically addressing the challenges presented by using two woofers with different diameters in a single enclosure. These new woofers incorporate all of Wilson’s latest thinking on accurate and musical low-frequency music reproduction. The Master Chronosonic’s heroic bass enclosure, with its unmatched ability to control and eliminate unwanted resonances, is the ideal platform in which to mount the Master Chronosonic’s bass drivers.
Midrange
Wilson’s MTM configurations, which feature time-domain adjustability, have always been far more sophisticated, complex, and musical than competing designs. Rather than mounting the three drivers that make up the MTM in a flat baffle, each driver is mounted in its own module. The modules are, in turn, adjustable relative to each other, which facilitates alignment in the critical time domain within the loudspeaker array. Another advantage to modularity is the ability to optimize the construction of each module, with the specific combinations of composites best suited to the needs of each driver. Led by Dave, Wilson Audio’s engineering team re-imagined the MTM geometry for the Master Chronosonic. The midrange is divided between two drivers, a seven-inch and four-inch for both the bottom and top portions of the MTM array. Each of the two drivers cover a portion of the midband area. The seven-inch is a bespoke modified version of the celebrated Wilson mid, first introduced in the Alexandria Series 2. The four-inch is an eminently musical driver that covers the important upper-midrange area up to the point where it crosses over to the Convergent Synergy Tweeter. The frequencies covered by the two drivers are therefore both expanded upward and downward in frequency when compared to previous Wilson designs—the two together covering a broader portion of the midrange. Furthermore, each driver is optimized for the portion of the midband best suited to its unique strength. Dave masterfully blended the two sets of mid drivers, ensuring that they perform seamlessly and coherently together.
