YG Acoustics New Speaker: Sonja XV
YG Acoustics™ (www.yg-acoustics.com), the leading ultra-highend speaker manufacturer, is proud to announce its latest creation Sonja™ XV.
Sonja™ XV is an extreme, four-tower version of Sonja™, created to celebrate YG Acoustics™’ upcoming 15 year anniversary (2002-2017). It combines everything that YG Acoustics™ knows 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 ... handmade in U.S.A. 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. The bass, midbass and midrange units are made in-house using YG Acoustics™’ proprietary BilletCore™ technology: the drivers are precisely machined out of massive slabs of aircraft-grade aluminum. This unique process offers overwhelmingly superior dynamics, musical delicacy and low distortion due to industry-leading rigidity and accuracy (tight tolerances). A pair of Sonja™ XV utilizes a total of 18 BilletCore™ drivers. The brand new BilletDome™ tweeter is YG Acoustics™’ most complex mechanical invention to date: a resonance-free soft dome is supported by a stiff, light airframe machined from aluminum billet. The airframe weighs a mere 30 milligrams (a thousandth of an ounce), but its critical sections are up to 14 times thicker than a typical hard dome, so its structural strength is vastly superior even to domes made of the most exotic hard materials. Finally, a tweeter that ends the age-old debate of hard versus soft, by combining the best of both. The tweeter’s motor is YG Acoustics™’ ingenious ForgeCore™ system: in-house CNC-cutting introduces sophisticated 3D geometries into the magnet system. The resulting improvement is greatly reduced distortion and a sense of ease to the sound. YG Acoustics™ crossover circuits are all created using proprietary software developed entirely in-house. DualCoherent™ technology provides the best frequency response and relative phase available. Competing speakers are optimized in either the frequency domain (most common) or time domain. Only YG Acoustics™ has the ability to optimize both domains simultaneously. Sonja™ XV’s bass crossover uses a brand new technology: ViseCoil™ inductors are CNC-wound in-house, then encased in a vise-like milled structure to eliminate vibration and tighten tolerances. Residual loss is reduced by 24%, and linearity is improved by 60%. The result is better control over the woofers, far greater bass impact, and an easier job for most amplifiers. Sonja™ XV’s mid and tweeter crossover uses ToroAir™ technology: in-house CNC-wound toroidal air-core inductors are unique in eliminating cross-talk (cross-contamination) common in crossover circuits. The result is preservation of high-frequency detail without harshness, brightness or sibilance. Sonja™ XV’s exquisite cabinet combines visual refinement with over-engineering. It is constructed of precision-machined aircraft-grade aluminum alloy. This material, using vibration-free pressurized assembly, allows for the most acoustically desirable enclosure achievable. The multi-layered structure is optimized for each module’s specific frequency range. This ensures the lowest vibration achievable, even at extreme volume levels. FocusedElimination™ anti-resonance technology keeps mechanical losses lower than any competing speaker, by combining the minimized turbulence of a sealed design with the low friction otherwise associated with enclosure-free concepts. YG Acoustics™ speakers are not voiced. All measurements are verified using extensive listening tests, but the speakers are not artificially manipulated. YG Acoustics™ speakers simply convey the recording – nothing more, nothing less. The end-result: Sonja™ XV is the closest that YG Acoustics™ has ever come to the natural sound of a live performance. It will be heard by few and attained by even fewer, but those who hear it will likely echo the statement that YG Acoustics™ President Yoav Geva made upon finishing his masterpiece: “From now on, when I listen to music, I want it to be either live or with Sonja™ XV”. Expansions and Upgrades Existing pairs of YG Acoustics™ Sonja™ can be expanded to Sonja™ XV, without the need to replace the speakers. Sonja™ XV, in addition to its state-of-the-art two-channel (stereo) performance, is also fully compatible with multi-channel audio and home-theater systems. Sonja™ XV can also be combined with speakers from YG Acoustics™’ other lines for properly phase-coherent multi-channel systems.
