Hertz ST 25K Neo.2 pair of high efficiency compression drivers 100 W, 4 Ohm

The bullet tweeters of the NEO line are a totally new design, lighter and more compact than the previous ST 25 and with superior performance thanks to the use of neodymium N38 H for the motor units and an optimized driver/horn design with FEM (Finite Element Method). The "Kit" version, ST 25K Neo, is equipped with metal grille and inline crossover filter included.

Main Features

  • Powerful neodymium magnet that guarantees high performance with compact dimensions.
  • Phase plug and loading horn optimized with FEM (finite element method).
  • CCAR (Copper Clad Aluminium Ribbon) voice coil for unprecedented thermal and mechanical capabilities, ready for easy replacement with the replacement kit.
  • Ultralight aluminum diaphragm to maximize SPL with high current screw terminals.
  • Waterproof body and UV anti-treatment to allow safe outdoor use without discoloration over time.
  • "Kit" version with metal grille and inline crossover filter included.
