The Reference range demonstrates the very best that can be achieved in accuracy and musicality, and we are honored that these models are some of the most awarded loudspeakers in the world. Their designs combine the most advanced materials with advanced science and engineering, all without compromise, and all with the singular aim of transporting the listener into the heart of the music.
Sonja XVi is an extreme, four-tower version of Sonja 2.3i. It combines everything that we know about speaker design with next-generation technologies that cannot be found elsewhere. Sonja XVi – an entirely new sonic benchmark, truly extreme in every way.
Remarkable in both form and function, Sonja XVi 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.
The Reference speakers are structured entirely from high-grade aerospace aluminum, machined in-house to incredible precision. With thousands of individual, precision-machined parts in each cabinet of the largest models, these speakers are painstakingly hand-built by experts in our Colorado workshop.
Our BilletCore drivers are cone-drivers machined from solid billet, offering some of the highest performance and lowest distortion in any driver available today. Combined with our ForgeCore and BilletDome tweeters, they allow the Reference range to achieve an exceptional level of accuracy, transient response, dynamics and musicality.
Crossovers constructed from the highest quality components are designed and tuned using proprietary, in-house modelling. They offer exceptional amplitude response across frequencies and incredible phase alignment across the crossover range.
