JL Audio C3-650

JL Audio C3-650 | C3 Series 6.5" Convertible Component System

The JL Audio C3-650 (Part Number: 010-03172-00) is an incredibly versatile system designed for enthusiasts who want premium performance without being locked into a specific mounting style. Known as a "Convertible" system, it can be deployed as a true component set with separate woofers and tweeters, or as a high-end coaxial by mounting the tweeter directly onto the woofer's pole piece. This flexibility makes it the perfect problem-solver for vehicles with difficult factory locations.

Product Highlights

• Convertible Versatility: Whether you need a separate woofer and tweeter for a better soundstage or a space-saving coaxial setup, the C3-650 handles both. Switching between configurations takes only a few seconds using the included phase plugs and tweeter mounts.

• Pure Silk Dome Tweeters: The 1-inch (25 mm) silk dome tweeters deliver a smooth, natural high-frequency response. Silk is chosen for its inherent damping properties, which eliminate the "harshness" often associated with metal dome tweeters.

• DMA-Optimized Bass: The woofers utilize JL Audio’s proprietary Dynamic Motor Analysis (DMA) to ensure the motor remains linear under high power. This results in tight, articulate mid-bass that remains clean even during aggressive musical passages.

• Elevated Frame Cooling: The woofer basket design incorporates patented cooling technology that pumps air directly over the voice coil. This prevents thermal compression and ensures the speakers sound just as good at the end of a long drive as they did at the start.

Key Features

• Premium Outboard Crossovers: This system includes a true two-way passive crossover network featuring midrange compensation and a 4-position tweeter level control. This allows you to calibrate the brightness of the system based on your interior acoustics.

• Long-Excursion Design: Featuring oversized 1.2-inch voice coils, these woofers are built for high output. The long-excursion capability allows them to move more air, providing a richer, more impactful low-end than standard factory replacements.

• Mineral-Filled Polypropylene Cone: The woofer cone is mineral-filled for added stiffness and durability, ensuring accurate reproduction of mid-range frequencies and vocals.

• Flexible Fitment: The system includes multi-application adaptor rings, making it compatible with a wide variety of 6.5-inch and 6.75-inch factory locations.
