KICKER acoustic engineers spent two years tweaking and fine-tuning the most serious statement ever from the first name in bass, and the results are ridiculously scary. New for this year, presenting three select versions of the original sub monster… KICKER SoloX™ Subwoofer.

How do you improve on a patented mechanical brute? Since the 18-inch S18X debuted in 2003, KICKER engineers have been working to make SoloX more advanced. This year they went all the way, creating the world’s ultimate bass machine.

Patented square subwoofer technology designed with the serious autosound competitor in mind, SoloX Subwoofers go where no others can. The 10-inch S10X, the 12-inch S12X, and the absurd S18X… it’s KICKER ingenuity to the umpteenth power. The SoloX earmark is the SPAIR (Simple Pull Apart Insertable Replacement)™, the patented cone/coil assembly that differs from other field-replaceable cones because the woofer’s cast-aluminum basket and massive motor assembly (BAM) remains intact in the enclosure during reload. In 2008 the SPAIR, just as the SoloX itself, withstands unnatural amounts of abuse while retaining the infrastructure for thunderous bass that earned it both competitive SPL (sound pressure level) and sound-quality world championships within weeks of its original release. Additionally, the newest SPAIR retro-fits into the previous generation of SoloX BAM if needed, with no modification.

More KICKER firsts provide protection against ruthless heat and other potential hazards. The distinctive UniPlate V.2â„¢ hyper-extended, pole/backplate assembly stays cooler with X-Ventâ„¢ technology (pat.pend.), yielding enhanced heat transfer for maximum power handling as well. This breakthrough in subwoofer motor construction increases linear magnetic fields around the coil gap for superior cone-motion control, all while releasing pressure under the cone for freer suspension and enhanced low bass. OK, it slams.

Further heat dissipation comes from the vented pole’s ARCTIC (Aluminum Rapid Cooling Thermal Induction Centering) Cap™, creating a Venturi-effect and forcing greater amounts of cooling air through the X-Vent, all while its high mass acts as a heat sink. SoloX’s dual voice coils and copper-clad-aluminum, edge-wound coil wire are oversized to withstand extreme heat too. No KICKER woofer possesses this many features to remain so reliable.

Additional cooling comes from KICKER’s perimeter venting™, pumping out heated air trapped beneath the S10X and S12X’s S3 Triple Spider Array™ and replacing it with cooling outside air (Quad Spider Array on the S18X). The one-piece, injection-molded cone’s new spoke design supplies structural bracing and contains a rolled outer edge to increase rigidity and decrease flex under high excursion. Stitched surround helps to prevent cone/surround separation. SoloX subs also utilize removable spring-loaded binding posts, making connection to any type or size of wire quick and easy.

For complete system flexibility, SoloX comes available with dual 2-Ohm or dual 4-Ohm voice coils, as do respective SPAIR models.
