JBL Stage3 507CF 5.25" 2-Way Component Car Speaker System

JBL Stage3 507CF 5.25-Inch Two-Way Component Car Audio Speakers

The JBL Stage3 507CF is a high-performance 5.25-inch (130mm) two-way component speaker system engineered to replace standard factory car speakers and elevate vehicle sound quality. Featuring independent edge-driven dome tweeters alongside JBL’s patented Plus One polypropylene woofer cones, this component system delivers precise high-frequency detail, smooth mid-range clarity, and extended low-end response. Built with a 3-ohm high-efficiency design, the Stage3 507CF maximizes output power when driven by factory head units or aftermarket car amplifiers.

• Component Speaker Design: Separate woofer and tweeter configuration allows for optimal acoustic placement and superior sound staging inside the vehicle.
• Plus One Polypropylene Woofer Cones: Patented cone surface technology provides up to 35% more surface area than standard 5.25-inch speakers for deeper bass and improved output efficiency.
• Edge-Driven Dome Tweeters: Delivers crisp, smooth high-frequency dispersion for detailed vocals and instruments without harshness.
• High-Efficiency 3-Ohm Architecture: Low-impedance architecture extracts maximum power from factory stereos and external amplifiers for punchier, clearer sound.
• Vented Basket Frame Design: Keeps voice coils cool during extended playback to ensure long-term power reliability and reduce thermal distortion.
• External Inline Crossovers: Directs specific frequency bands cleanly to the woofers and tweeters for balanced sound distribution.
