Sonja™ XV is an extreme, four-tower version of Sonja™, created to celebrate YG Acoustics™’ 15 year anniversary (2002-2017). It combines everything that we know about speaker design, and incorporates several next-generation technologies that cannot be found elsewhere. Sonja™ XV – an entirely new sonic benchmark, truly extreme in every way.
Innovations include, first and foremost, a breakthrough tweeter made in-house, and proprietary cost-no-object bass inductors. These enhancements, together with an ability to move near-limitless amounts of air, result in an effortless listening experience that is typically only associated with a live musical performance.
