The
JBL Stage3 68C is
a high-performance 6.5-inch (165mm) 2-way component car speaker system. Unlike the standard coaxial models in the Stage3 line, the 68C is a component kit that separates the woofer from the tweeter. This design allows you to position the drivers independently inside your vehicle to build a much wider, more realistic front soundstage. This package is
sold with grilles included.

Component-Level Engineering Breakdown
-
Edge-Driven Silk Dome Tweeters: While standard coaxial Stage3 models use PEI balance domes, the premium component 68C upgrade features separate edge-driven silk dome tweeters. Silk naturally reduces structural harmonic distortion, providing a significantly smoother, wider, and completely fatigue-free high-frequency response.
-
Laser-Etched Glass-Fiber Plus One™ Woofer: The mid-bass driver relies on HARMAN's patented Plus One™ cone shape to claim up to a 35% increase in total cone surface area within the same 6.5" frame. Made from a polypropylene blend reinforced with 10% glass fiber, the laser-etched treatment gives the cone rigidity to stay perfectly flat under heavy bass loads.
-
External Inline Passive Crossovers: The system ships with dedicated crossover boxes. They automatically filter unwanted low frequencies away from your silk tweeters and block high frequencies from your mid-bass woofers, protecting your gear and ensuring smooth transitions.
- Eco-Minded Engineering: The speaker frames utilize post-consumer recycled plastic elements, integrate fully PVC-free layout wiring, and pack inside shipping boxes utilizing soy-based inks.
