Sonja XV is an extreme, four-tower version of Sonja, created to celebrate YG Acoustics’ 15 year anniversary. It combines everything that we know about speaker design with next-generation technologies that cannot be found elsewhere. Sonja XV – an entirely new sonic benchmark, truly extreme in every way.


Remarkable in both form and function, Sonja XV introduced BilletDome, a one-of-a-kind resonance-free tweeter machined from aircraft-grade aluminum billet, as well as ViseCoil, a ground-breaking bass inductor that reduces residual loss and improves linearity, to the audiophile community. Both precision-crafted in-house enhancements, together with an ability to move near-limitless amounts of air, result in an effortless listening experience associated with the finest live musical performances.
