L7 Subwoofers

Style. Substance. The L7™ brings award-winning innovation to you with the original square subwoofer.

L7 Series Main

Square Matters

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

L7 Series Square Matters

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.

L7 Series Massive Motor

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.

L7 Series Keep it Cool

Lean in the Corners

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

L7 Series Lean in the Corners

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.
