Hertz ST 35A NEO SPL Show 1.8" Aluminum Dome Bullet Tweeter (Pair)

46 (1.8) mm (in.) | High Efficiency Compression Driver | 120 W | 4 Ohm
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. The “Active” version, ST 35A Neo provides tweeter only.

Features:

1. Powerful Neodymium magnet providing high performance with compact size.

2. FEM (Finite Element Method) optimized phase-plug and loading horn.

3. CCAR (Copper Clad Aluminum Ribbon) voice coil for unheard-of thermal and mechanical capability ready for an easy replacement with replacement body kit.

4. Extra-light aluminum membrane to maximize SPL with high current, screw terminals.

5. Body waterproofing and anti-UV treatment to allow safe outdoor use without discoloration over time.

6. Aluminum back cover for superior heat dissipation.

7. Impressive low frequency extension and efficiency.
