JBL Stage3 427 4" 2-Way Coaxial Car Speakers with Grilles (Pair)

JBL Stage3 427 4-Inch Two-Way Coaxial Car Audio Speakers

The JBL Stage3 427 is a pair of compact 4-inch (100mm) two-way coaxial car audio speakers engineered to upgrade factory-installed vehicle sound systems. Combining JBL’s patented Plus One polypropylene woofer cone architecture with edge-driven dome tweeters, these speakers deliver enhanced low-end output, clear vocals, and smooth high frequencies. Designed with 3-ohm high-efficiency architecture, the Stage3 427 extracts maximum power from low-output factory head units or aftermarket amplifiers for crisp, full-range dynamic audio.

• Plus One Polypropylene Woofer Cones: Patented cone design offers up to 35% more surface area than standard 4-inch speakers for improved bass response and overall efficiency.
• Edge-Driven Dome Tweeters: Provides broader high-frequency dispersion and smoother, non-fatiguing vocal delivery.
• High-Efficiency 3-Ohm Architecture: Low-impedance design draws more power from head units and amplifiers to boost output efficiency without distortion.
• Vented Basket Frame Design: Helps cool the internal voice coils to ensure long-term power handling and thermal reliability.
• Compact OEM Fit: Designed to fit directly into standard 4-inch factory speaker locations in a wide variety of vehicles.
