Hertz DCX 570.3 | Dieci Series 5" x 7" Two-Way Coaxial Speakers
The Hertz DCX 570.3 is a high-efficiency coaxial speaker designed to provide premium sound quality with minimal installation effort. Part of the acclaimed Dieci series, these speakers feature a neodymium magnet and a PEI dome tweeter to ensure a detailed high-frequency response. Engineered with a lightweight yet rigid structure, they deliver a linear frequency response and high sensitivity, making them an excellent choice for upgrading factory systems in vehicles that utilize 5x7 or 6x8 inch mounting locations.
Product Highlights
Water-Repellent Pressed Paper Cone: The woofer utilizes a water-repellent treated paper cone, which provides a natural sound while ensuring durability against the humidity often found inside car doors. This stiff, lightweight material allows for accurate mid-bass reproduction and a smooth transition to the higher frequencies.
PEI Dome Tweeter with Neodymium Magnet: High frequencies are handled by a 15mm (0.6 in.) PEI dome tweeter. Driven by a high-energy neodymium magnet, this tweeter offers superior high-frequency extension up to 21 kHz and excellent off-axis dispersion, ensuring clear sound throughout the vehicle's cabin.
TPU (Thermoplastic Polyurethane) Surround: The woofer cone is supported by a TPU surround, which is designed for wide linear excursion and resonance damping. This material helps maintain sound purity even at high volumes, reducing unwanted vibrations and distortion.
High Sensitivity Design: With a sensitivity rating of 93 dB, the DCX 570.3 is extremely efficient. This allows the speakers to produce significant volume and clarity even when powered by a standard factory head unit, providing a substantial performance boost without the immediate need for an external amplifier.
Key Features
Built-In Crossover: The integrated passive crossover ensures a seamless blend between the woofer and the tweeter. This built-in design simplifies the installation process by eliminating the need for external boxes or complex wiring.
Pure Copper Voice Coil: Wound on a conex former, the 1-inch (25 mm) pure copper voice coil is designed for maximum lightness and thermal stability, allowing for reliable performance during long, high-volume listening sessions.
Large Motor Assembly: Despite its compact design, the speaker features a large motor assembly with a high-density flux ferrite magnet. This provides the necessary force for precise voice coil control and punchy low-frequency output.
Optimized Dimensions: The 2.6-inch (66 mm) mounting depth and standard DIN-size basket make these speakers compatible with a wide range of Ford, Mazda, and Chrysler vehicles that use 5x7 or 6x8 inch factory speaker openings.

What Others Are Saying
Eddie was great - SDCS installed a new head unit in my 2019 4Runner. He was honest in his opinions regarding the options I was considering. Pricing was also good - he was able to reuse some of my existing installation kit so I saved a bit of $$.Installation was clean and fast and he took the time to walk through the features before I left. Highly recommend!!
I had a great time at this shop! The staff really knows their stuff and took the time to explain the different options without pressure. Installation was quick, clean and professional. Everything looks factory and sounds amazing. The prices were fair and customer service was above and beyond. I highly recommend this place if you're looking for quality car audio and excellent service.
Those guys are really professional! I had a new Alpine floating head unit installed in my 2008 Mercedes, and it feels like a brand-new car. The installation was super clean. At first, the sound wasn’t the same as the factory stereo, but Kevin tuned it to be just as good—if not better—without adding any new amps. They even used my factory GPS antenna so I don’t have extra wires hanging out. On top of that, they matched the online price. Big thanks to Kevin and Eddie—highly recommended!
Kevin was awesome, he took his time and explained everything to me. I went in initially for a dash cam install and then decided to get a sub and amp installed as well. Both turned out great and will be returning if I need more work done.
Came In not knowing what to expect when suddenly my stereo stopped working. Spoke with Kevin in the front and after a VERY fast diagnosing they discovered my wiring was incorrect. After only about 45 minutes total being in the store I was on my way to the beach with a working stereo again! Thank you so much SDCARSTEREO
Highly recommend Kevin and the team at San Diego Car Stereo for any issues with aftermarket stereos. I bought a car with an aftermarket stereo and AC unit that wasn’t working properly—specifically, the heat wasn’t functioning due to an improper setup. I had several people look at it with no luck, and even the dealership basically refused to help because it was an aftermarket install. I came to Kevin and his team over the holidays feeling pretty defeated, but he was confident he could get the heat working before I headed back to a Colorado winter. Sure enough, he got it done.
