Sonja™ is YG Acoustics™’ flagship, and represents everything that we know about speaker-design. Driven by innovative applications of acoustical engineering and world-class precision-manufacturing, Sonja™ pushes the edge of the art. Marrying these elements with stunning industrial design, results in a loudspeaker which is transformative in both performance and sheer visual beauty. Sonja™ - unparalleled sonics, timelessly elegant form, pure seduction... handmade in U.S.A.
Innovations include, first and foremost, breakthrough drivers machined in-house, and proprietary toroidal air-core crossover inductors. These enhancements result in ultra-low distortion, while preserving the industry-leading frequency and phase response that YG Acoustics™ is famous for.
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 tweeter incorporates YG Acoustics™’ ingenious ForgeCore™ system: in-house CNC-cutting introduces sophisticated 3D geometries into the motor 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™’s 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™’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™ 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™ is available in four fully modular configurations, each of which can be expanded to the next, without the need to replace existing modules:
• Sonja™ 1.1 – an ultra-high-end compact speaker.
Available with or without a matching stand.
• Sonja™ 1C – a center-channel speaker.
Available with or without a matching stand.
• Sonja™ 1.2 – an ultra-high-end medium-sized floorstanding speaker.
Consists of Sonja™ 1.1 interlocked atop a matching bass module.
• Sonja™ 1.3 – the flagship; an ultra-high-end large floorstanding speaker.
Consists of Sonja™ 1.1 interlocked atop dual matching bass modules.
Existing Anat™ speakers (serial #036 and upward) can be upgraded to Sonja™ technology, without the need to replace the speakers. 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.
Sonja™ is fully compatible with multi-channel audio and home-theater systems. Sonja™ speakers can also be combined with speakers from YG Acoustics™’ other lines for properly phase-coherent multi-channel systems.
