JBL – S2-1224


SSI™ (Selectable Smart Impedance)

Most car audio system designs call for 2- or 4-ohm impedance. Series II 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.

Building Flexibility

Series II woofers incorporate a high-roll surround that provides superior cone edge suspension while maximizing excursion. It not only increases the cone area, it also provides remarkable linear stability and reliability.

Proprietary cone design

JBL subwoofer cones aren’t just built to thump, they’re built to last. Series II woofers feature an exclusive cone design that delivers superior rigidity for long-lasting performance.

Long excursion design

The longer a subwoofer’s excursion is, the more air it moves. And the more air it moves, the more bass you feel. The long-excursion design in Series II subwoofer ensures big, deep bass output. Just the way you like it.
