Hertz DCX 460.3 4x6-Inch Two-Way Coaxial Speakers

The Hertz DCX 460.3 is a pair of 4 x 6-inch, two-way coaxial car speakers designed for vehicles that use this compact oval factory speaker size. They provide a direct speaker-upgrade option for drivers seeking clearer everyday playback from compatible factory or aftermarket audio systems. Their coaxial layout combines the woofer and tweeter into each speaker for a space-efficient installation.

With 40 watts continuous power handling and 93 dB sensitivity, the DCX 460.3 is suited to systems powered by a factory radio, aftermarket receiver, or appropriately matched external amplifier. The 4-ohm impedance is common in car-audio speaker installations. Its 65 Hz to 21 kHz frequency response covers core midrange, upper bass, and treble duties.

The sound design centers on a water-repellent pressed-paper woofer cone paired with a PEI dome tweeter. This combination is intended to reproduce vocals and instruments through the midrange while adding high-frequency detail from the centrally mounted tweeter. A TPU surround supports cone movement and helps control resonance.

Hertz uses a high-density-flux ferrite woofer magnet, a neodymium tweeter magnet, and a pure-copper woofer voice coil wound on a Conex former. The 25 mm woofer voice coil and large motor assembly are engineered for controlled driver operation. A built-in crossover directs appropriate frequency ranges to the coaxial drivers.

These speakers work well as replacements in compatible 4 x 6-inch door, dash, or rear-deck locations where installation depth and mounting pattern are verified first. Their 53 mm mounting depth and specified mounting dimensions should be compared with the vehicle opening before purchase. They can serve as a practical full-range speaker upgrade or as part of a broader system refresh with an upgraded receiver and properly matched amplification.

Key Features

• 4 x 6-Inch Coaxial Format: Fits compatible oval speaker locations with integrated woofer and tweeter drivers.
• Two-Way Design: Separates midbass and treble reproduction within each speaker assembly.
• 40W Continuous Handling: Supports properly matched factory-radio or amplifier power.
• Water-Repellent Paper Cone: Treated woofer cone helps resist moisture exposure.
• PEI Dome Tweeter: Compact dome tweeter handles high-frequency playback.
• Built-In Crossover: Directs frequencies between the woofer and tweeter.

Design & Installation

The DCX 460.3 uses a water-repellent pressed-paper cone, TPU surround, ferrite woofer magnet, and neodymium tweeter magnet. Its pure-copper voice coil is wound on a Conex former, while the DIN-size basket has abrasion-resistant dust paint. Tin-plated high-current terminals and silver-plated lead wires support secure electrical connections.

Confirm the vehicle's 4 x 6-inch opening, mounting dimensions, available depth, and factory mounting pattern before installation. The speaker has a 53 mm depth, with published A1, A2, B1, B2, C, and D mounting dimensions that should be checked against the installation location. Use an amplifier or receiver appropriate for 4-ohm speakers and avoid exceeding the 40-watt continuous power rating per speaker.
