Sonja 1.3

About the Sonja 1.3

The YG Acoustics Sonja 1.3 is the flagship model in the Sonja series, consisting of the Sonja 1.1 module interlocked atop dual matching bass modules, creating a large floorstanding speaker. It delivers exceptional sound quality with a usable frequency output extending from below 20 Hz to above 40 kHz, ±1 dB deviation in the audible band, and ±5° relative phase throughout the entire overlap. The speaker uses proprietary BilletCore ultra-high-rigidity woofers and mid-woofers, and a ForgeCore ultra-low-distortion tweeter. It features a fully passive design with a proprietary DualCoherent crossover at 65 Hz and 1.75 kHz, designed with in-house software, and ToroAir inductors to eliminate cross-talk. Sensitivity is 88 dB at 2.83 V/1 m, with a nominal impedance of 4Ω (minimum 3Ω). The Sonja 1.3 weighs 230 kg (506 lbs) per channel and measures 179 x 43 x 72 cm (70 x 17 x 28 inches). It is known for its immaculate build quality, spectral balance, effortless resolution, and natural sound that sets benchmarks in transparency, 3D soundstaging, and dynamics. The speaker is modular and can be expanded from the Sonja 1.1 and 1.2 configurations. It is fully compatible with multi-channel audio and home theater systems and can be combined with other YG Acoustics speakers for phase-coherent systems. The Sonja 1.3 is highly regarded in the audiophile community and
