Hertz ECX 690.5 Energy Series 3-Way 6" x 9" Coaxial Speaker (Pair)

The Energy.5 ECX 690.5 car audio coaxial is a three-way coaxial, features a dome tweeter with high-energy magnet as well as a PEI supertweeter with built-in crossover, providing maximum efficiency and extended high-frequency response.
Its large motor assembly and rubber magnet cover ensure excellent mobile voice coil control and mechanical damping to the basket and motor structure, providing fluid, undistorted acoustic emission.


1. Water-repellent treated paper cone, butyl rubber surround.
2. Pure copper voice coil wound on aluminium former, for very good thermal
and mechanical capacity.
3. Large motor assembly for excellent mobile voice coil control.
4. Low carbon content plates for maximum magnetic permeability and high
heat dissipation.
5. Rubber magnet cover provides damping to the basket and motor structure
and protects from abrasions and damages.
6. DIN size basket coated with scratch-proof, corrosive-resistant material.
7. Tin-plated, high current terminals.
8. Silver-plated lead wires, for maximum reliability and conductivity.
9. Epoxy glue for basket and motor system provides perfect coupling.
10. Curve memory Nomex spider for consistent, reliable performance.
11. Dome-cone tweeter with high energy neodymium magnet combined with a
PEI supertweeter. The best possible efficiency and high frequency extension.
