About the Hertz C 165
Build your Cento system
Build your Cento system
The Cento Series sounds like magic — but it's actually the result of carefully considered design and materials by Hertz's team of experts. The C 165 6-1/2" woofer uses a semi-pressed paper and mica powder woofer cone to deliver 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. Incorporate a pair of these impressive speakers into your next custom system.
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.

Features
Size Classification Note: Some manufacturers, including Hertz, call this size woofer a 6½". Because it requires a larger cutout than a standard 6½" speaker, Crutchfield has traditionally referred to this size speaker as a 6¾". Please enter your vehicle information to confirm fit.
Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and computer software to do large-scale analysis of drivers in motion, helps Hertz optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.
