The following is a press release issued by YG Acoustics.
Arvada, CO | July 29, 2016 – YG Acoustics™ (www.ygacoustics.com), the leading ultra-high-end 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 (20022017). 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, mid-bass 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 viselike 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 crosstalk (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 multilayered 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 multichannel audio and home-theater systems. Sonja™ XV can also be combined with speakers from YG Acoustics™’ other lines for properly phase-coherent multichannel systems.
