Hertz ECX570.5 Energy 5x7" Coaxial Speakers

The Energy.5 ECX 570.5 car audio coaxial is the solution for those who want to reproduce a wide frequency range without the need of separate components: the coax tweeter adds to the woofer response optimizing the installation-friendliness.
Neodymium tweeter with built-in crossover, pressed-paper cone with deep ribbings for maximum rigidity and accurate optimization of the motor assembly contribute to enhance sound linearity, off-axis response and timbre quality. Thanks to the RHFC technology, the tweeter can be oriented, being 10° angled, to control dispersion and get close to the ideal frequency response.

Technologies

Rotary High Frequency Contour

The tweeter group is adjustable and can be oriented towards the listening point. This means no limits to the installation: with the RHFC system you can tune the response for any listening point. For perfect off-axis dispersion and frequency response.
