Club 122. Subwoofer 12" 400W RMS 2Ω/4Ω JBL Club subwoofers deliver deep powerful bass that will take your system to the next level. SSI™ (Selectable Smart Impedance) Most car audio system designs call for 2- or 4-ohm impedance. Club Series subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option depending on your particular system and amplifier choice. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch. Double Stack Magnet Design for Big Power Handling Club subwoofers are equipped with double-stacked magnet, allowing the voice coil coupled with the high roll surround to travel over a longer excursion. Vented Basket Design for System Cooling Club subwoofer vented basket keeps voice coil cool even at high output levels to ensure long term reliability. High-Roll Rubber Surrounds Club subwoofers incorporate a high-roll surround that provides stronger cone edge suspension while maximizing excursion. It not only increases the cone area, it also provides remarkable linear stability and reliability. Purposeful Design JBL Club Subwoofers feature a large inverted dust cap mated to a JBL orange cone with a subtle reveal for a pop of color. The slash pattern forms a JBL Horn prominently on the dust cap. The unique surround design allows the trim ring to press fit into it and conceal any fasteners. This gives the subwoofers a sleek clean appearance when installed. *By request/order.
