Hertz DCX570-3 5x7" 2-Way Coaxial Speakers

The Hertz DCX570-3 is a pair of 5 x 7-inch, two-way coaxial car speakers designed for factory-speaker replacement and straightforward system upgrades. Its integrated tweeter and woofer arrangement places the main drivers in one compact assembly. This approach helps bring full-range playback to vehicles that use a 5 x 7-inch speaker location.

With 60 watts continuous power handling and a 4-ohm nominal impedance, these speakers are suited to compatible factory radios or external car-audio amplification. The 93 dB SPL sensitivity specification supports efficient output from appropriately matched equipment. Their published frequency response spans 60 Hz to 21 kHz.

The DCX570-3 uses a water-repellent pressed-paper woofer cone with a TPU surround. This combination is paired with a 25 mm pure-copper mobile voice coil wound on a Conex former. A high-density-flux ferrite woofer magnet supports the motor assembly.

High frequencies are handled by a 15 mm tweeter using a neodymium magnet and PEI dome. The speaker includes a built-in crossover, so a separate external passive crossover is not specified for normal operation. Its coaxial layout keeps the installation focused around one speaker mounting position per channel.

For a practical upgrade, the DCX570-3 can be used as a matched left/right pair in a compatible 5 x 7-inch location. Verify vehicle-specific mounting dimensions, mounting-hole pattern, depth clearance, and wiring connections before purchase. Pairing the speakers with a source unit or amplifier that is compatible with their 4-ohm load and power rating helps create an appropriate system match.

Key Features

• Two-Way Coaxial Design: Combines woofer and tweeter in each speaker assembly.
• 5 x 7-Inch Woofer: Fits applications designed for this speaker size.
• 60W Continuous Power: Supports appropriately matched factory or amplified systems.
• Water-Repellent Paper Cone: Uses treated pressed paper for the woofer cone.
• PEI Dome Tweeter: Handles high frequencies with a compact 15 mm dome.
• Built-In Crossover: Integrates frequency division within the coaxial speaker.

Design & Installation

The DCX570-3 combines a high-density-flux ferrite woofer magnet with a neodymium tweeter magnet. Its construction includes a TPU surround, pure-copper voice coil on a Conex former, tin-plated high-current terminals, and silver-plated lead wires. Hertz also specifies an abrasion-resistant painted basket, butyl-rubber protective cover, epoxy bonding between basket and motor system, and low-carbon-content plates.

Confirm that the vehicle accepts a 5 x 7-inch speaker and that its available depth meets the 66 mm mounting-depth specification. Check the supplied mounting drawing dimensions against the factory opening, as adapters, brackets, hardware, or wiring connections may be vehicle-specific. Connect each speaker to a compatible 4-ohm channel and observe the power limits of the complete audio system.
