SoloXS L7XS
The Biggest and Baddest!
We call it L7 "Excess" - meet the SoloXS L7XS Subwoofer, with exceptionally high power handling like nothing we've designed before! We're talking handling 1,000-plus RMS watts more than the amazing SoloX.
Pro-Class Bass is Meaner
The obvious use of square SoloXS line is to crank out ridiculous decibel readings during competition, but you'll find L7XS is incredibly musical as well.
Different from the Others
You'll notice the difference immediately after viewing the size of the massive ferrite magnet, responsible for an Xmax of more than 43 millimeters (1.71"). Most every aspect of the SoloXS line is definitely another step up from the SoloX Subwoofer.
"The concept of the SoloXS and SoloX is to take bass to the next level. They are designed with very tight tolerances. They have more power, more stroke, more Xmax and still have field-replaceable cones. This new design allows Pro-Class Subwoofers to be extremely loud but also extremely musical."
- KICKER President Steve Irby
Keeping It Cool
Heat is the enemy of endurance. To make L7XS even more reliable, KICKER engineers developed optimized Forced-Air Cooling™ thermal management which helps SoloXS Subwoofers run significantly cooler and last longer.
The Music Never Stops On-Site
Using an exclusive, surround compression system, bolt-on spider landing, and helpful alignment pins, the L7XS pre-assembled recone assembly gets you from blown to bumpin’ in minutes – no gluing ever!


SoloX History
There's a reason we compete. The ceaseless drive to learn, improve and ultimately - to win - is indelibly woven into KICKER's DNA.
In the early 2000's, car audio competition was thriving, and KICKER was dominating the lanes - winning world championships both in sound pressure and sound quality. Leading the charge was Alma Gates, her legendary “Beast" Bronco, and the KICKER Competition Group. We watched the KICKER Competition Group collect a seemingly endless streak of awards, earning trophy after trophy – championship after championship – all while using high-power-handling, high-efficiency SoloX Subwoofers.
As time went by, we labored to create another generation of high-SPL subwoofer. We experimented with ideas, threw them away and made something better. We scoured social media discussion groups, looking for every burp, demo and hair trick we could find. We asked elite competitors their opinions (the first time in our history we did so before production was underway), and then, during our streaming hit show “KICKER UnMASKED! Live," we unveiled it online to record-breaking crowds.
We invite you to experience the legend for yourself, for one reason: we made something better.
