ST 25K NEO 44 (1.8) mm (in.) | High Efficiency Compression Driver | 100 W | 4 Ohm


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. The “Kit” version, ST 25K Neo features metallic mesh grille and inline crossover filter included.
