Upgrade your factory audio system with the JL Audio C2-650x 6.5-inch 2-way coaxial car speakers, engineered to deliver premium full-range sound with exceptional clarity and detail. Whether you're replacing worn-out factory speakers or building a high-performance car audio system, the C2-650x offers smooth, balanced sound, impressive dynamics, and the renowned reliability that JL Audio is known for.
The JL Audio C2-650x features a durable mica-injected polypropylene (MIPP) woofer cone paired with a long-lasting butyl rubber surround to produce accurate midrange, punchy midbass, and low distortion even at higher listening levels. JL Audio's advanced Dynamic Motor Analysis (DMA) technology improves cone control for cleaner, more detailed audio while maintaining consistent performance during extended playback.
A 0.75-inch silk dome tweeter delivers warm, natural high frequencies with excellent detail and minimal listening fatigue, making the JL Audio C2-650x ideal for every music genre. The integrated crossover network ensures seamless blending between the woofer and tweeter while protecting both drivers from unwanted frequencies. The result is crisp vocals, accurate instrument reproduction, a wider soundstage, and an immersive listening experience that outperforms typical factory speakers.
