JBL Stage3 648F Speakers

The JBL Stage3 648F 4"x6" (100x152mm) coaxial speaker embodies 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. Additionally, the PEI balanced dome tweeter ensures improved sound distribution, resulting in crystal-clear highs and creating an immersive listening experience that elevates your car audio setup. 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.

• Oval Plus One™ Woofer Architecture: HARMAN’s patented design pushes the speaker's rubber surround out to the absolute margins of the oval basket frame. This configuration increases the total effective cone surface area by up to 35% over competing 4x6" options, maximizing air displacement for a punchier mid-bass response.
• Laser-Etched Glass-Fiber Cone: The primary woofer core utilizes heavy-duty polypropylene reinforced with 10% glass fiber. The specialized laser-etched treatment keeps the rigid cone perfectly flat under rapid bass notes, eliminating unwanted acoustic flex or distortion.
• PEI Balanced Dome Tweeters: Crisp and distributed high frequencies are handled by Polyetherimide (PEI) balanced dome tweeters. PEI channels thermal heat away efficiently, stabilizing high vocals and instruments so they stay vibrant across the cabin without causing listener ear strain.
• Environmentally Focused Build: Built using sustainable engineering rules, the basket infrastructure integrates post-consumer recycled plastic properties, routes currents through PVC-free speaker wiring, and packages inside clean boxes printed with soy-based inks.
