A subwoofer that puts you in the driver’s seat

JBL believes sound quality should never be compromised. And Series III subwoofers make sure you don’t have to compromise flexibility, either. That’s because the high-performance, step-up subwoofers feature SSI™ (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance—2 or 4 ohms—for your system. Special aero-cooling design in the voice coil boosts power handling as well as reliability. And an oversized voice coil handles more power than common two-inch voice coils. More power, more reliability, more flexibility—and no compromising. When you’re ready to step up, Series III is your subwoofer.

Most car audio system designs call for 2- or 4-ohm impedance. Series III subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.
The Series III voice coil significantly increases power handling and improves reliability by going with the flow—of air. The woofer’s motor channels air pumped by the cone movement past the voice coil, and the voice coil former exposes the coil’s inner and outer surfaces to the airflow. This aero-cooling design is unique among aftermarket subwoofers.
The three-inch (75mm) voice coil proves you don’t have to be a heavyweight to pack a serious punch. It handles more power than conventional two-inch voice coils, yet it’s lighter than four-inch voice coils. It strikes the perfect balance between thermal power handling and low mass.
Power is the lifeblood of any subwoofer. The terminals on the Series III accommodate up to 8-guage wire (8.37mm2 cross section), which transfers low-resistance, low-loss power to the woofer, even over long wire runs. This ensures the subwoofer—and your music—has the power it needs.
