JBL S3-1024 10" Subwoofer with Selectable Impedance
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.
Series III woofers delivers the enhanced efficiency and higher output.
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.
The Series III voice coil significantly increases power handling and improves reliability by going with the flow of air.
Features & benefits SSI™ (Selectable Smart Impedance)
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.
High-roll surround
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.
Proprietary cone design
JBL subwoofer cones aren't just built to thump, they're built to last.
Long excursion design
The longer a subwoofers excursion is, the more air it moves. And the more air it moves, the more bass you feel. The long-excursion design in Series III subwoofer ensures big, deep bass output.
strikes the perfect balance between thermal power handling and low mass.
