JBL S3-1024 User Manual
Series III Subwoofers
10" (250mm) and 12" (300mm) high-performance car audio subwoofers
A subwoofer that puts you in the driver’s seat.
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 these high-performance subwoofers feature SSI
Smart Impedance), a patented impedance switching technology that lets
you select the optimum impedance – 2 or 4 ohms – for your system.
We have also engineered aero-cooling in the voice coil to boost power
handling as well as reliability. Plus our 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 Subwoofers

Features and Benefi ts
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 reconfi gure your system
by simply fl ipping a switch.
Aero-cooled voice coil
The Series III voice coil signifi cantly increases power handling and
improves reliability by going with the fl ow – of air. The woofer’s
motor channels air pumped by the cone movement past the voice
coil, and the voice coil former exposes the coil’s inner and outer
surfaces to the airfl ow. This aero-cooling design is unique among
aftermarket subwoofers.
Oversized voice coil
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. It strikes the perfect balance between thermal power
handling and low mass.
Premium screw-down terminals
Power is the lifeblood of any subwoofer. The terminals on
the Series III accommodate up to 8-guage wire (8.37mm2
cross section), which transfers low-resistance, low-loss
power to the woofer, even over long wire runs. This
ensures the subwoofer – and your music – has the power
it needs.
