JBL Stadium 122SSI 12-Inch High Performance Switchable Subwoofer - 500W RMS
The JBL Stadium 122SSI puts you in control of your bass. With 500W RMS (1,500W peak) power handling, this 12-inch subwoofer delivers deep, clean, and powerful bass for any car audio system. In addition, its Selectable Smart Impedance (SSI™) lets you choose either 2 or 4 ohms, allowing for multiple system configurations. This flexibility ensures you can easily integrate it into both single and multi-subwoofer setups.
Innovative Design for Reliability
Aero-Cooled Voice Coil: The subwoofer features a unique aero-cooling system that channels air past the voice coil. This keeps the coil cool, even at high output levels, improving reliability and long-term performance.
Oversized 2-Inch Voice Coil: Despite its compact size, the 2-inch (50mm) voice coil handles more power than conventional coils while remaining lighter than larger 4-inch coils. This ensures a perfect balance between thermal power handling and low mass, delivering responsive, distortion-free bass.
Premium Push Terminals: The integrated terminals accommodate 8 AWG wire for low-resistance, low-loss power transfer, even over long wire runs. This ensures your subwoofer receives consistent power for optimum performance.
