Tweeter
In conjunction with WAMM and Alexx, Daryl Wilson and Wilson’s team of engineers revisited the current state of the art of 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. Yet again, 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 MK5 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 cumulative 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.
Enclosure Materials
Most loudspeaker manufacturers are content with building enclosures from medium-density fiberboard—a material originally used in the construction of tract-home sub floors. In contrast, Wilson has spent the last several decades researching and developing cutting-edge composites.
Aerospace-Grade Aluminum
The infrastructural Gantry supporting the timedomain adjustability—the Master Chronosonic Micrometer—is constructed from aerospace-grade aluminum. One of aluminum’s virtues is modulus of elasticity. This quality, combined with relatively low mass, resistance to corrosion, and low toxicity, make it an excellent material to form the adjustable support structure for the modules, ensuring that the overall rigidity of the module launch points is maintained. Because even the best aluminum is not well suited for driver interface or module damping, the Master Chronosonic employs Wilson’s composites, X-, W-, and S-Materials in these locations. The aluminum is finished in a beautiful prismatic machined pattern, calling to mind the Guilloché finish of the finest Swiss watches.
