Hertz SPL Show ST 25K NEOFeatures Metallic Mesh Grille And Inline Crossover Filter Included

NEO line bullet tweeters are a totally new project, lighter and more compact compared to the previous ST 25 and with superior performance thanks to the use of Neodymium N38 H for the motor units and a FEM (Finite Element Method) optimized driver/horn design.

Highlights

  • Powerful Neodymium magnet providing high performance with compact size.
  • FEM (Finite Element Method) optimized phase-plug and loading horn.
  • CCAR (Copper Clad Aluminium Ribbon) voice coil for unheard-of thermal and mechanical capability ready for an easy replacement with replacement body kit.
  • Extra-light aluminium membrane to maximize SPL with high current, screw terminals.
