  • Vented voice coil former for reduced distortion and compression
  • Vented chassis for lower air flow speed reducing audible distortion
  • Voice coil wound with Copper Clad Aluminium Wire for higher efficiency and better dynamics
  • Heavy-duty black fiber glass voice coil bobbin to increase power handling and reduce mechanical losses resulting in better dynamic performance and low-level details
  • Low-loss suspension (high Qm) for better reproduction of details and dynamics
  • Black magnet parts for better heat transfer to increase power handling
  • Progressive suspension with specially designed CONEX damper (spider) for long durability under extreme operating conditions
  • Gold plated terminals to prevent oxidation for long-term reliable connection
