Product Information

41L7154 15" Q-Class L7 Subwoofer w/ Dual 4-Ohm Voice Coils

The L7 stands alone as the most unique subwoofer on the market, with a cone shape that is exclusively designed to produce more output.

Square Matters

A KICKER® original, their square subwoofers deliver 20% more surface area than a comparable circular sub. A bigger cone moves more air, so you get more sound!

Massive Motor

Extreme power handling needs a motor worthy of the KICKER name. Oversized magnets and an aluminum voice coil allow every drop of power to get from the sub to your ears.

Keep it Cool

The Uniplate™ is a KICKER original, combining the pole piece and back plate as a single, seamless unit to pull damaging heat away from the sub. With heat management this advanced, you get the bass you crave – for as long as you crave it.

Lean in the Corners

Kicker's patented Santoprene™ corners allow your KICKER subs to play smooth, distortion-free music at any volume level.

Strong Suspension

Kicker's Blue Lace™ spider and ribbed surround work together to give you the best suspension for your L7. You get unparalleled accuracy and volume to feel every note - every time.

The New L7

The KICKER L7™ Subwoofer again reaches new heights in technology and design, capturing the imaginations of 2015 CES® Innovation Award judges and solidifying itself as the crown jewel among industry subwoofers. For more than a decade, KICKER’s square woofer earned numerous awards including several CES accolades, and the 2015 version once again makes distinctive improvements on its way to another honor.

Which is the better woofer L715 or the P2 Rockford fosgate woofer?
A shopper on Jun 9, 2020
  Hi and thanks for reaching out. We are not a Rockford Fosgate dealer, so I can't directly answer your question. However, we have been a Kicker dealer for years and I will tell you that I am continuously impressed with the Q-Class subwoofer series from them. They are one of the few subwoofers that offer excellent sound quality while doing its best to rattle your rearview mirror off of the windshield. You will not regret the Kicker Q-Class L7 subwoofer. Hope this helps!
