Hertz SX 690 NEO.1 6" x 9" SPL Show Series 3-way Coaxial Car Speakers
High-performance 3-way coaxial speakers engineered for extreme SPL applications
The Hertz SX 690 NEO.1 represents advanced 6" x 9" coaxial speaker engineering, featuring a 3-way configuration with dual tweeter design for maximum sound pressure level performance. This SPL Show Series speaker incorporates a Hi-SPL Mid-Hi unit with 1.4" dome tweeter and 1" dome super tweeter, both protected by resettable solid-state protection circuits. The pressed paper cone features water/humidity resistance and anti-UV treatments for durability in automotive environments.
The speaker utilizes special Neodymium N38 H magnets in the tweeter assemblies for minimal bulk and enhanced performance, while the double-layer copper voice coil wound on polyimide former ensures exceptional power handling capabilities. Each speaker includes the MPG 690 grille with high-resistance ABS plastic structure, metallic finish, and protective metal mesh.
