Hertz CPX165 6.5" Two-Way Coaxial Speakers

The Hertz CPX165 is a 6.5-inch two-way coaxial speaker designed for vehicle audio upgrades where a compact full-range speaker is needed. Its coaxial layout places the tweeter and woofer in one assembly, helping simplify installation in compatible factory speaker locations. The 4-ohm design makes it suited to systems built around compatible aftermarket or factory amplification.

This model is intended for listeners seeking clearer, more controlled reproduction than worn or basic factory speakers can provide. It combines a pressed-paper woofer cone with a soft Tetolon dome tweeter to cover midrange and high-frequency duties from one mounting position. With a specified frequency response of 45 Hz to 22 kHz, it is designed to handle a broad portion of the audible range.

The CPX165 is rated for 95 watts continuous power handling and 285 watts peak power handling. Its 25 mm pure-copper woofer voice coil is paired with a high-density-flux ferrite magnet assembly. The tweeter uses a neodymium magnet and a ferrofluid-cooled 20 mm voice coil.

Hertz uses a Radial Venting System with eight venting holes to promote voice-coil cooling and air exchange behind the tweeter. The speaker also uses a 3-spoke basket and an anti-vibration rubber magnet cover to help manage unwanted mechanical vibration. An integrated crossover is specified at 4 kHz with a 6 dB-per-octave slope.

These speakers can serve as a practical upgrade in compatible front-door, rear-door, or rear-deck locations, subject to vehicle fitment verification. Their 165 mm nominal size, 65.5 mm mounting-depth dimension, and 171 mm outside dimension should be checked against the vehicle before installation. Hertz lists the CPG165 protective grille as an optional accessory for installations where a grille is needed.

Key Features

• Two-Way Coaxial Design: Combines woofer and tweeter in one speaker assembly.
• 95W Continuous Handling: Supports compatible amplified audio systems.
• Pressed-Paper Cone: Balances cone rigidity with low moving mass.
• Tetolon Dome Tweeter: Reproduces upper-frequency detail with a soft dome.
• Integrated Crossover: Directs high frequencies to the tweeter.
• Radial Venting System: Uses eight vents for voice-coil cooling.

Design & Installation

The CPX165 uses a pressed-paper woofer cone, high-density-flux ferrite woofer magnet, neodymium tweeter magnet, and Tetolon dome. Its woofer has a 25 mm pure-copper voice coil, while the tweeter uses a 20 mm ferrofluid-cooled voice coil. The compact 3-spoke basket is paired with an anti-vibration rubber magnet cover.

Confirm the vehicle's speaker opening, available mounting depth, mounting-hole pattern, and trim clearance before purchase. The manufacturer drawing lists a 65.5 mm mounting-depth dimension and 171 mm outside dimension, so adapters or spacers may be required depending on the vehicle. Connect the speakers to a compatible 4-ohm source and match amplifier output responsibly to the 95-watt continuous power rating.
