Wilson Audio WAMM, Master Chronosonic™

You, noble Art, in how many grey hours, when life’s mad tumult wraps around me, have you kindled my heart to warm love, have you transported me into a better world, transported into a better world!” To my mind, this is what Dave Wilson has accomplished with the WAMM Master Chronosonic.

Wilson Audio WAMM, Master Chronosonic™


It’s About Time

This video previews the long awaited WAMM, Master Chronosonic™, Dave Wilson’s Magnum Opus. Nearly five years of research, development, and thought have gone into the new WAMM. Now, as a preface to its launch in a few months, we offer up this small homage to Dave, a visionary who has indelibly changed the way we all think about music and its reproduction.


  • Daryl Wilson and Wilson’s team of engineers recently concluded another round of research and development into tweeter technology.
  • Wilson’s MTM configurations, which feature time-domain adjustability, have always been far more sophisticated
  • Unlike the original WAMM, which required a subwoofer to cover the bottom octaves, the Master Chronosonic is a true full-range design

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.
