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.
