Hertz DCX160-3 6" Two-Way Coaxial Speakers

The Hertz DCX160-3 is a pair of 6-inch two-way coaxial car speakers designed for replacing compatible factory door or rear-deck speakers. Its coaxial layout places the tweeter and woofer in one assembly, helping simplify an upgrade where separate tweeter mounting is not desired. With a 4-ohm nominal impedance and 60-watt continuous power handling, it is suited to factory-radio upgrades or properly matched aftermarket amplification.

These Dieci-series speakers are intended for listeners seeking a straightforward full-range replacement speaker with integrated high-frequency reproduction. The woofer uses a water-repellent pressed-paper cone and TPU surround, materials selected to support controlled movement and everyday automotive use. A built-in crossover directs frequencies between the woofer and tweeter within each speaker assembly.

The DCX160-3 combines a high-density-flux ferrite woofer magnet with a neodymium tweeter magnet. Its PEI tweeter dome is integrated at the center of the woofer, allowing a compact two-way design that fits applications where a conventional round 6-inch speaker is appropriate. Hertz rates the pair's frequency response from 50 Hz to 21 kHz and sensitivity at 93 dB SPL.

For installation durability, Hertz specifies a DIN-size basket with abrasion-resistant dust paint, tin-plated high-current terminals, and silver-plated lead wires. The woofer uses a pure-copper voice coil wound on a Conex former, while the basket and motor system are joined with epoxy adhesive. These construction details support an OEM-style speaker replacement while retaining serviceable connection points.

The manufacturer includes an adaptor ring intended for select GM and Honda vehicles equipped with 6-inch OEM speakers. Fitment is still vehicle-dependent, so the mounting dimensions and available mounting depth should be checked before installation. The DCX160-3 can serve as a direct full-range speaker upgrade in a compatible location or as part of a larger system with matched amplification and bass support.

Key Features

• Two-Way Coaxial Design: Integrates woofer and tweeter in each speaker for simplified installation.
• 60-Watt RMS Handling: Supports properly matched factory or aftermarket power.
• Water-Repellent Paper Cone: Helps the woofer suit typical automotive door environments.
• PEI Dome Tweeter: Provides dedicated high-frequency reproduction from the coaxial assembly.
• Built-In Crossover: Separates woofer and tweeter frequencies within each speaker.
• GM/Honda Adaptor Ring: Supports installation in select vehicles with 6-inch OEM speakers.

Design & Installation

The DCX160-3 uses a high-density-flux ferrite woofer magnet, neodymium tweeter magnet, water-repellent pressed-paper cone, and TPU surround. Its pure-copper voice coil is wound on a Conex former, while the DIN-size basket has an abrasion-resistant dust-painted finish. Tin-plated terminals, silver-plated lead wires, a butyl-rubber protective cover, and low-carbon-content plates are also specified by Hertz.

Confirm vehicle fitment by comparing the manufacturer-listed 167 mm outside diameter, 127 mm physical dimension B, 66.5 mm depth, and 56.5 mm physical dimension D with the available mounting location. Wire each speaker with correct polarity to a compatible 4-ohm amplifier or head-unit channel, and do not exceed its 60-watt continuous power rating. For used speakers, verify the condition and included hardware, including the adaptor rings, before installation.
