Sonja™ 2 incorporates YG Acoustics™' latest technologies, BilletDome™ and ViseCoil™, which until now were exclusive to the flagship Sonja™ XV. Marrying these technological breakthroughs with stunning industrial design, the result is a loudspeaker which is transformative in both performance and sheer visual beauty. Sonja™ 2 has unparalleled sonics, timelessly elegant form and pure seduction. Precision crafted in Colorado, U.S.A.
Sonja™ 2 is distinguished first and foremost by the patent-pending BilletDome™ tweeter. BilletDome™ 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 dome versus soft dome, combining the best of both.
Sonja™ 2'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.
The 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).
The BilletDome™ tweeter’s motor incorporates 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™ 2’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™ 2’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™ 2 sets benchmarks in transparency, 3D-soundstaging, dynamics, bandwidth, inner-detail and the natural sound of a live performance that YG Acoustics™ is famous for. This is all presented in a refined, elegant speaker with an exquisite fit and finish that is the showpiece of the world’s finest listening environments.
Sonja™ 2 is available in four fully modular configurations, each of which can be expanded to the next, without the need to replace existing modules:
• Sonja™ 2.1 – an ultra-high-end compact speaker, available with or without a matching stand.
• Sonja™ 2C – a center-channel speaker, available with or without a matching stand.
• Sonja™ 2.2 – an ultra-high-end medium-sized floorstanding speaker.
Consists of Sonja™ 2.1 interlocked atop a matching bass module.
• Sonja™ 2.3 – an ultra-high-end large floorstanding speaker.
Consists of Sonja™ 2.1 interlocked atop dual matching bass modules.
Sonja™ 2, in addition to its remarkable two-channel (stereo) performance, is fully compatible with multi-channel audio and home theater systems.
A hallmark of YG Acoustics™ speakers is their future-proof design. Owners of most Anat™ and Sonja™ (1st generation) speakers enjoy the ability to upgrade to our latest Sonja™ 2 technology, and/or to expand to the Sonja™ XV flagship. In most cases, upgrades and expansions can be done in the field (i.e. in the customer’s home) without the need to ship the speakers anywhere, in a matter of hours.
