Description
Discover the SPL SHOW ST 25A Neo.2, the latest horn tweeter from the renowned Hertz company. This innovative model impresses with its lightness and compactness compared to its predecessor, the ST 25, and offers outstanding performance thanks to the use of N38 H neodymium for the motor units and an FEM-optimized driver/horn design. Particularly noteworthy is the "active" version - the ST 25A Neo, which is designed exclusively as a tweeter. With a high-performance neodymium magnet, optimized phase plug and loading horn, as well as lightweight aluminium cones, this model sets new standards in terms of sound power and quality.
