Description


JBL brand icon

Authorized dealer



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, And an oversized voice coil handles more power than common voice coils.


Key Features:

    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.

    Oversized voice coil


    The two-inch voice coil proves you don't have to be a heavyweight to pack a serious punch. It handles more power than conventional voice coils, yet it's lighter than three-inch voice coils. It strikes the perfect balance between thermal power handling and low mass.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

Check out the JBL S2-1224 Owner's Manual

*Infinite-baffle mounting is possible, but the subwoofer's mechanical power handling will be reduced because there will be no volume of air to stiffen the subwoofer's suspension and prevent overexcursion. If you choose infinite-baffle mounting, consider the RMS and peak power-handling ratings to be half of what is listed

These subs slams. Best subs I had yet

Today I just got these subs installed. They are absolutely amazing out the box can't wait to break them in. If you are hesitant about these don't be cause JBL quality is as good as JL audio any day. This was a great buy I recommend you get a custom box to fit them to the right specs.

So versatile!

I love the fact that this product can switch between 2 ohm and 4 ohm! It makes pairing this sub with any system a breeze! Not to mention it is LOUD. Pair it with a nice amp and box and you got yourself a great system!

ran the subs off a 500 watt Kenwood amp the subs were way louder and cleaner than 2 JL 12w0 in the same brand and size prefab boxes.
