Description
You are looking at the SPL SHOW ST 25K Neo.2, a pioneering horn tweeter from Hertz. This innovation from the NEO line impresses with its light and compact design. The unique performance is achieved by using neodymium N38 H for the motor units and a driver/horn design optimized by FEM (Finite Element Method). Particularly noteworthy is the "kit" version of the ST 25K Neo, which includes a metal grille and an inline crossover filter. Expert tips: This tweeter enables high performance in a compact size, thanks to a powerful neodymium magnet, FEM-optimized phase plug and loaded horn. With waterproof and anti-UV treatment, it is also prepared for safe outdoor use.
