Hertz SPL Show ST 35A NEOProvides Tweeter Only
NEO line bullet tweeters are a totally new project, lighter and more compact compared to the previous ST 35 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.
