About: JBL Stadium 122SSI 12" High-Performance Car Audio Subwoofers

JBL believes sound quality should never be compromised and the Stadium subwoofers make sure you don’t have to compromise flexibility, either. That’s because these high-performance subwoofers feature SSI™ (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance—2 or 4 ohms—providing multiple system configurations and flexibility. A special aero-cooling design keeps the voice coil cool even at high output levels. This feature coupled with oversized voice coils increases power handling and ensures long term reliability. More power, more reliability, more flexibility—and no compromises. When you’re ready to step up, Stadium is your subwoofer.

SSI (Selectable Smart Impedance) 

Stadium subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. This allows for a variety of system configurations when using one subwoofer or multiples. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.  

Aero-cooled Voice Coil 

The Stadium's 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. The areo-cooling design is unique among aftermarket subwoofers. 

Oversized Voice Coil

The 2-inch (50 mm) voice coil proves you don't have to be a heavy weight to pack a serious punch. It handles more power than conventional two-inch voice coils. It strikes the perfect balance between thermal power handling and low mass. 

Premium Integrated Push Terminals

Power is the lifeblood of any subwoofer. The terminals on the Stadium subwoofer accommodates 8 AWG wire, which transfer low-resistance, low-loss power to the woofer, even over long wire runs. The is ensures the subwoofer and your music has the power it needs.
