QS Component and Point Source speakers are more than just the best sounding drivers Kicker's ever made. They’re a technical marvel. Using Kicker's signature Tri-Tech™ cone on the separates and Kevlar-impregnated Polypropylene on the coaxials, Tetoron® dome tweeters and metallized polypropylene capacitors, QS speakers deliver the sparkling highs and hyper-accurate midrange you need to feel like you’re front row center!
Belonging to Kicker's flagship Q-Class, the Kicker Q-Class 41L7122 is a 12-inch subwoofer that comes with unique features and premium audio quality. Kicker L7s has always been considered a top-notch product line in the market, and this subwoofer is no exception to that reputation.


The two subwoofers come with polypropylene cones for high audio quality and minimal distortion, and foam surrounds for better bass performance; stitched together, it adds durability that enables the subwoofers to be used for extended periods at cranked-up volume levels.
As the subwoofer has more surface area to work with than other subwoofers, it allows for more air movement resulting in a louder bass. It comes with a SoloKon polypropylene cone, and Santoprene surround, stitched together, resulting in premium bass performance, minimal distortion, and durability to last long, even with extended usage periods at higher volume levels.


Featuring Kicker's trademark UniPlate feature that combines the back plate and pole piece as a single unit and a massive cast aluminum basket, the subwoofer has an excellent heating management system that allows for efficient heat dissipation, protecting your subwoofer from getting damaged after a long time of use at very high volume levels.
Thanks to its massive motor, the Kicker Q-Class 41L7122 has a power output of 900 Watts RMS and can go up to 1,800 Watts of peak power at a 2-ohm impedance. Its frequency response of 20 up to 100 Hz and sensitivity of 86.9 dB means that the subwoofer is ready to play any bass-filled tracks at high volumes with minimal distortion only.
