JL Audio C3-570cw | Evolution C3 Series 5" x 7" Component Woofer (Single)
The JL Audio C3-570cw (Part Number: 010-03841-00) is a high-performance 5" x 7" / 6" x 8" midrange driver sold as a single unit. Engineered for maximum versatility, it features a unique convertible design that allows it to function as a dedicated midrange in a component system or be transformed into a coaxial speaker with the addition of a C3 tweeter (sold separately). With its DMA-optimized motor, it delivers a punchy, low-distortion performance that matches the output of high-quality 6.5-inch round speakers.
Product Highlights
Mineral-Filled Polypropylene Cone: The C3-570cw utilizes a mica-filled polypropylene cone and a durable rubber surround. This combination provides the stiffness and damping required for accurate, high-detail midrange reproduction and a smooth roll-off.
DMA-Optimized Motor Structure: Using JL Audio's proprietary Dynamic Motor Analysis (DMA), the motor is engineered to maintain a stable magnetic field over a wide range of power. This reduces distortion and ensures the speaker stays clean and controlled, even when pushed to its limits during high-volume sessions.
Elevated Frame Cooling (EFC): The patented Elevated Frame Cooling design delivers cool air directly to the voice coil through slots in the frame. This thermal management improves power handling and minimizes power compression, keeping your audio consistent during long periods of use.
Convertible Design with Phase Plug: This woofer comes with a removable component phase plug. For component installations, the phase plug improves high-frequency dispersion; for coaxial setups, it can be swapped with a tweeter post to mount a C3 tweeter directly in the center of the woofer.
Key Features
Injection-Molded Polymer Basket: The woofer is housed in a glass-filled polymer frame that is both corrosion-resistant and non-magnetic. This robust structure prevents interference with the motor's magnetic field, ensuring pure sound reproduction.
Oversized 1.2-inch Voice Coil: The large-diameter voice coil provides superior power handling and thermal capacity compared to standard speakers, allowing for a more robust and "meaty" mid-bass response.
Superior Oval Performance: JL Audio’s engineering ensures that this oval driver delivers the same cone area and efficiency as a 6.5-inch round speaker, proving that you don't have to sacrifice performance to fit a factory oval opening.
Clean and Powerful Sonic Character: Tightly controlled by a flat spider and advanced motor modeling, the C3-570cw is designed for listeners who demand a high-impact, audiophile-grade midrange performance.

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.
