YG Acoustics is pleased to announce DualCoherent 2, a significant advance in one of their core and unique technologies. "DualCoherent 2 builds on YG’s industry-leading DualCoherent crossover technology, further optimised through the powerful modelling capabilities of Cambridge Acoustic Sciences (CAS). Working together with CAS, we measured the electronic and acoustic behaviour of our proprietary drive units to an unprecedented accuracy. Leveraging the petaflop compute cluster at CAS, we were able to build detailed models addressing the elaborate interplay of amplifier, crossover, drive units, cabinet and listening room—all simulated playing real, high-resolution music."

"Designed and optimised exactingly around the detailed phase and frequency behaviour of the YG proprietary drivers, DualCoherent 2 matches phase to an extraordinary level at the crossover point. In addition, current requirements are substantially reduced, further extending the range of amplifier choices available to customers.

DualCoherent 2 is implemented with the finest audio electronic components, including the massive and highly vibration-resistant ViseCoilTM bass inductors machined and built in-house by YG. Other components include cost-no-object choices such as Mundorf MCap SUPREME EVO SilverGold capacitors and MResist SUPREME resistors.

DualCoherent 2 was originally conceived for implementation in the Sonja XV platform. Additional substantial research and development has resulted in the extension of DualCoherent 2 crossover technology throughout the Sonja product line.

Going forward, all Sonja XV, Sonja XV Studio and Sonja 2 series speakers will include an "i" suffix in the model name. The "i" designation will indicate an improved version of the model by the inclusion of DualCoherent 2 crossover technology.

All previous Sonja XV, Sonja XV Studio, Sonja 1 series and Sonja 2 series speakers can be upgraded

to DualCoherent 2 specification. This upgrade can be accomplished "in the field". There is no need to return speakers to the factory."
