This Product Features:
- Angled Tweeters: are mounted such that the tweeters can be directed toward the listeners to improve the experience. Additionally, these tweeters post rotates -approximately 270°, so you can direct the tweeters in any direction once they have been mounted
- Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and computer software to do a large-scale analysis of drivers in motion. The KDA helps Hertz optimize the speaker’s motor composition, voice coil alignment, and suspension to yield the stablest possible execution.
- 4/2 Hole Compatibility: In some vehicles, only two mounting screws are used and most use four. However, the CX 100 Series mounting tabs can be removed allowing the versatility of installation on either 4 or 2 hole applications.
Hertz CX 100 2-way excellence
These Hertz Cento Series CX 100 4″ 2-way car speakers employ a Tetolon dome tweeter designed to deliver superior dispersion. The semi-pressed paper and mica powder woofer cone uphold your music’s lower frequencies with accuracy and impact. Excellent 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.
The Hertz philosophy
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. A community of music lovers, Hertz is committed to optimizing your car’s sound system for total audio enjoyment.
