Hertz Cento CPX 690 Pro

The CPX 690 Pro is a 3-way coaxial speaker built for enthusiasts who want highly dynamic sound with strong low-frequency performance from a rear parcel shelf position. The tweeter and supertweeter both use neodymium magnets and Tetolon domes. The faceplate geometry is FEM-optimised to maximise off-axis emissions, making it well suited to horizontal installation.

Both the tweeter and supertweeter feature Hertz's Radial Venting System for improved cooling and acoustic performance. The basket also uses radial ventilation to keep operating temperatures low. The supplied grille combines a high-resistance ABS plastic frame with a protective metallic mesh.

  • Pressed paper cone with FEM-optimised geometry for rigidity, lightness and accurate sound reproduction.
  • Wide rubber suspension for long excursion and effective sound damping.
  • High-density ferrite magnet with low-carbon polar plates to reduce distortion at high power levels.
  • Metal-finished basket with anti-vibration rubber magnet cover to damp spurious vibrations.
  • 32 mm Tetolon dome neodymium tweeter with 28 mm voice coil for distortion-free mid-high frequency reproduction.
  • 24 mm Tetolon neodymium supertweeter with 20 mm voice coil to compensate for high-frequency roll-off in horizontal installations.
  • FEM-optimised faceplate geometry for linear frequency response in off-axis installations.
  • Grille with high-resistance ABS plastic frame, metal finish and protective metallic mesh.

About the Hertz CPX 690 PRO

From our tech experts at CEN

Hertz Cento series 6x9 inch coaxial pair, with the tweeter in the centre of the woofer, rated at 120w RMS.

Who it suits

Drivers replacing tired factory speakers who want a clear improvement without complication.

Our tech experts advise

Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Door treatment matters as much as the speaker itself, and an amplifier will get far more out of these than a head unit can. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions

Q: Will these speakers fit my car?

A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.

Q: Do I need an amplifier to run these speakers?

A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.

Q: What is the difference between coaxial and component speakers?

A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.

Q: Do these come as a pair?

A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.

Q: Can CEN fit these speakers for me?

A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.

Q: Where does the Hertz CPX 690 Pro fit?

A: It is a 6x9 inch 3-way coaxial designed to make the most of the rear deck (parcel shelf) mount, with a faceplate optimised for horizontal installation.

Q: Are grilles included with the CPX 690 Pro?

A: Yes. The box contains the 3-way speakers, grilles, grille mounting rings, screws, speed clips, an owner's manual and a template on the box.

Q: How much power does the CPX 690 Pro handle?

A: It handles 120 W continuous and 360 W peak at 4 ohms, with a frequency response of 35 Hz to 24 kHz.
