Hertz DCX 170.3 6.7" 2-Way Coaxial Car Speakers - Pair
Hertz DCX 170.3 6.7" 2-Way Coaxial Car Speakers - Pair
A pair of flat-profile 6.7" two-way coaxial speakers engineered for shallow door panels and factory-restricted installation spaces, the DCX 170.3 delivers refined acoustic performance through a neodymium PEI dome tweeter, water-repellent pressed paper cone, TPU surround, and a maximum depth of just 51mm.
Product Overview
The Hertz DCX 170.3 is a 170mm (6.7") two-way coaxial car speaker built around a shallow 51mm maximum depth profile, making it an optimised solution for vehicle door installations and other locations where mounting depth is restricted. Sold as a pair, the DCX 170.3 is a direct upgrade for vehicles with factory 170mm speaker positions. Despite the compact depth, Hertz has retained a full-specification build that includes a high-density flux ferrite woofer magnet, a neodymium magnet PEI dome tweeter, a water-repellent pressed paper cone, a TPU (thermoplastic polyurethane) surround, a 25mm copper voice coil wound on a Conex former, and a built-in crossover, all contributing to acoustic performance Hertz positions above standard coaxial category expectations.
Handling 50W continuous and 100W peak at 4 ohms, the DCX 170.3 covers a frequency response of 60Hz to 21kHz and is compatible with both head unit outputs and modest aftermarket amplification. At 560g per speaker, the DCX 170.3 is lightweight for its build quality, and the mounting depth of 45mm to the basket of the magnet and 140mm mounting diameter suit the standard 6.5" cutout dimensions common across a broad range of vehicle door applications.
Features & Benefits
51mm Maximum Depth for Shallow Installation Environments: The DCX 170.3 is built to a maximum depth of 51mm, with a mounting depth of 45mm to the basket of the magnet, making it suitable for vehicle doors and panel locations where standard-depth coaxials cannot be fitted without modification. The shallow depth profile does not compromise the speaker's component specification or acoustic output.
Perfect Upgrade for Factory 170mm Speaker Positions: The DCX 170.3 is designed as a direct, high-performance upgrade for vehicles factory-equipped with 170mm speakers. The 140mm mounting diameter and 170mm overall diameter suit the standard cutout and grille opening dimensions common across a wide range of OEM door panels in the 6.5"-6.7" size class.
Neodymium Magnet PEI Dome Tweeter: The tweeter uses a neodymium magnet for a compact and powerful magnetic structure, paired with a PEI (polyetherimide) dome diaphragm that delivers detailed high-frequency reproduction with excellent thermal and mechanical stability. The built-in crossover directs the appropriate frequency range to the tweeter within the coaxial assembly.
High-Density Flux Ferrite Woofer Magnet: The woofer section uses a high-density flux ferrite magnet measuring 80 x 32 x 10mm, providing a strong and consistent magnetic field for controlled cone movement and accurate low-to-mid frequency reproduction.
Water-Repellent Pressed Paper Cone: The cone is constructed from pressed paper treated for water resistance, balancing the rigidity required for accurate pistonic motion with low mass for efficient transient response, and providing durability in door environments where moisture exposure is a factor.
TPU Surround: The thermoplastic polyurethane surround delivers controlled cone excursion with consistent mechanical properties across a wide temperature range, contributing to long-term durability and stable low-frequency roll-off characteristics.
Copper Voice Coil on Conex Former: The 25mm copper voice coil is wound on a Conex former, combining good thermal dissipation from the copper winding with the dimensional stability of the Conex material under sustained power handling conditions.
Built-In Crossover: The DCX 170.3 includes a built-in passive crossover that manages frequency distribution between the woofer and tweeter within the coaxial assembly, allowing straightforward installation without requiring external crossover components.
Sold as a Pair: The DCX 170.3 is supplied as a matched pair of speakers for a complete left and right channel upgrade in a single purchase.

Compatible With
The Hertz DCX 170.3 is designed as a direct upgrade for vehicles factory-equipped with 170mm speaker positions. The 140mm mounting diameter fits the standard 6.5"-6.7" cutout found in most vehicle doors, and the 170mm overall diameter suits standard speaker grille opening dimensions across a wide range of OEM door panels. At 4 ohms impedance, the DCX 170.3 is compatible with most aftermarket head units and car amplifiers. For amplified installations, an amplifier capable of 50W continuous per channel at 4 ohms is recommended to stay within the speaker's continuous power rating. Verify mounting depth and cutout dimensions against your specific vehicle door cavity before purchase.
Frequently Asked Questions
Why is the DCX 170.3 described as a flat or shallow-depth speaker?
The DCX 170.3 has a maximum depth of 51mm and a mounting depth of 45mm to the basket of the magnet. Many standard coaxial speakers in the 6.5"-6.7" size range exceed 60-70mm in maximum depth. The DCX 170.3's 51mm depth profile allows it to be installed in vehicle doors and panel locations that cannot accommodate deeper speakers without physical modification, making it a practical choice for a wider range of fitment scenarios without compromising the speaker's component build quality.
Is the DCX 170.3 compatible with standard 6.5" speaker cutouts?
Yes. The DCX 170.3 has a 140mm mounting diameter, which is consistent with the standard 6.5" speaker cutout dimensions used across most vehicle door panels. Confirm the cutout diameter, mounting depth clearance, and grille opening dimensions against your specific vehicle before installation.
Can the DCX 170.3 be driven directly from a head unit without an amplifier?
Yes. With a continuous power rating of 50W and a 4 ohm impedance, the DCX 170.3 is compatible with head unit outputs typically in the 18-50W per channel range. For higher output or a more dynamic listening experience, an external amplifier matched to the speaker's 50W continuous and 100W peak ratings at 4 ohms is recommended.
Does the DCX 170.3 require an external crossover?
No. The DCX 170.3 includes a built-in passive crossover within the coaxial assembly that manages frequency distribution between the woofer and PEI dome tweeter. No external crossover components are required for a standard installation.
How many speakers are included in a DCX170.3 purchase?
The DCX170.3 is sold as a pair, including two matched speakers for a complete left and right channel door speaker upgrade in a single purchase.
