3-way excellence. These Hertz Cento Series CX 690 6″x9″ 3-way car speakers employ a PEI dome tweeter and supertweeter designed to deliver superior dispersion. The semi-pressed paper and mica powder woofer cone upholds your music’s lower frequencies with accuracy and impact. Superior damping is also key to the sound of these speakers — minimized resonance reduces distortion for Hertz’s famous truer-to-life sound.
These are a great choice for the new enthusiast who’s ready to get serious about sound in their vehicle. Hertz believes that a good speaker should enhance the emotional power of the music you love. That’s a high bar, but with their commitment to using premium components and boundary-pushing design, they’re more than up to challenge.
