1x JBL STAGE3868F 6” x 8” 2-Way Coaxial Speaker No Grille (STAGE3868F)
High-performance speakers designed to deliver legendary JBL sound quality. The JBL Stage3 speakers embody JBL’s legendary sound, delivering powerful audio in the car. The woofer cone is manufactured using a laser-etched tool, features the patented Plus One™ design for increased surface area, and is reinforced with 10% glass fiber to play deeper, more resonant bass. The speaker’s true 4-ohm load design maximizes power output from your head unit or amplifier, compensating for system resistance to ensure optimal performance. Additionally, the speakers incorporate post-consumer recycled plastic components, PVC- free wiring, and packaging printed with soy-based inks, thereby minimizing environmental impact. Finally, precise fitment is critical to the success of this speaker family—ensuring seamless integration and consistent acoustic performance across vehicle platforms.
