AK ZERO2 “Quad-brid” design is centered around an advanced driver array and Super Low Noise Cross-Over Network perfectly tuned. Four different types of driver, including Custom BA Drivers, a Planar Dynamic Driver, a 10-mm Dynamic Driver, and a Piezoelectric Transducer create the perfect synergy, coming together to form the Quad-brid AK ZERO2 capable of reproducing the pure sounds that Astell&Kern strives to deliver.
3D Chambers - Each driver is placed optimally in an acoustic chamber that is created through refined 3D printing technology. This design eliminates any unnecessary movement and resonance of the drivers for permanently stable performance.
Crossover - The ultra-refined cross-over network enables a perfect balance between six drivers with distinctive sound characteristics, maximizing each of their acoustic traits while creating a balanced harmonized sound.
Two Cables, 3.5mm + 4.4mm Balanced: The pure silver-coated OFC cable, designed to maximize the performance of the AK ZERO2, is created with high-purity silver plating and copper, and adds a touch of style with plugs crafted from aluminum. The MMCX connectors offers a robust connection and a long-lasting and stable life cycle.
