AK Zero2

AK Zero2 Quadbrid IEM, by Astell&Kern. Made inn Japan, a new design for 2023, Zero2 features improved ergonomics and a more sophisticated array of drivers forming an amazing audio engine! Zero2 uses a metal shell with the following design elements:

• New Super Low Noise crossover
  
• 3D printed Acoustic Chamber inner form
• CNC Metal housing
• Piezoelectric driver (super highs)
• Micro Rectangular Planar Magnetic driver (highs)
• Dual BA drivers (mid-low)
• Dual BA drivers (mid)
• 10mmm Dynamic driver (lows)

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.
