JL Audio C3-525cw

JL Audio C3-525cw | Evolution® C3 Series 5.25" Component Woofer (Single)

The JL Audio C3-525cw (Part Number: 010-03348-00) is a high-performance 5.25-inch (130 mm) component woofer engineered for those who demand both power and installation flexibility. Sold individually, this driver is a "convertible" component, meaning it can be used as a dedicated woofer in a component system or transformed into a coaxial driver using JL Audio's specialized mounting hardware. It is built to deliver clean, articulate mid-bass and a smooth midrange response.

Product Highlights

• Convertible Flexibility: The C3-525cw is uniquely designed to solve installation challenges. It can be installed as a standard component woofer with a separate tweeter, or you can mount a C3 tweeter directly to its center pole for a high-end coaxial configuration.

• DMA-Optimized Motor: Using JL Audio's proprietary Dynamic Motor Analysis, the motor system is tuned to remain highly linear even under high power. This dramatically reduces distortion and ensures that transients—like a kick drum or bass pluck—are reproduced with exceptional precision.

• Elevated Frame Cooling: This patented design features slots directly above the top-plate that deliver cool air to the voice coil. By minimizing heat build-up, the speaker maintains its sound quality and power handling during long, high-volume listening sessions.

• Mineral-Filled Polypropylene Cone: The woofer cone is made from a mineral-filled polymer that provides a high stiffness-to-mass ratio. This results in impactful mid-bass and a natural, uncolored midrange that blends seamlessly with a tweeter.

Key Features

• Oversized 1.2-inch Voice Coil: The large voice coil provides superior thermal management and increased power handling compared to standard 5.25-inch drivers, allowing for extended dynamic range.

• Injection-Molded Polymer Basket: The basket is designed to be non-magnetic and resonant-free, providing a rock-solid foundation for the moving parts of the speaker.

• Integrated Phase Plug Support: When used in a component setup, the included phase plug replaces the tweeter post to improve high-frequency dispersion from the woofer's center.

• Premium Grille Included: Each unit comes with a durable black grille tray and a steel mesh insert featuring an electroformed JL Audio logo, protecting the driver without obstructing sound flow.
