About the Hertz CK 165
Premium materials and design
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 CK 165 component speaker system employs a separate Tetolon® dome tweeter for detailed sound defined by a natural timbre and smooth transitions. The semi-pressed paper and mica powder woofer cone delivers 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. The system’s external, compact crossovers feature two tweeter levels help you dial in the best sound in your 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.Product highlights:

Product Research
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.
Tweeter Mounting: Brackets are included for flush mounting and angled surface mounting (60° or 30°) the tweeters.
Note: We’ve found some Hertz speakers with the wrong size tweeter template on the box. Before cutting, make sure the template has the correct diameter.

| Depth | 0.46″ | N/A | N/A |
| Frame Diameter | 1.728″ | N/A | N/A |

Crossovers: Each crossover has a tweeter output level switch; choose between 0dB (flat) and +3dB. The crossover point is 2.5 kHz and the slope is 12 dB/octave (low pass and high pass). The inputs and outputs are screw terminals that will accept bare wire or spade connectors up to 0.315″ wide. The woofer has quick slide terminals, so crimp-on terminals can be added (item number 120FQS10PK, sold separately) to provide the needed terminals.

- Width: 4″
- Height: 1⅜”
- Depth: 3″
