The YG Acoustics – Sonja™ 1.2 Loudspeaker is simply one of our best:
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.
Speakers from YG Acoustics™’ Anat™ III, Anat Reference™ II and Anat Reference™ (serial #036 and upward) lines can be upgraded to Sonja™, without the need to replace the speakers. The products are mostly field-upgradeable, 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.
