STADIUM SUBWOOFERS
10" (250mm) and 12" (300mm) high-performance car audio subwoofers
Features and Benefi ts
SSI
™
(Selectable Smart Impedance)
Most car audio system designs call for 2- or 4-ohm impedance.
Stadium 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 Stadium 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 Stadium accommodate up to 8-guage wire (8.37mm
2
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.
