All About Kicker SoloX L7X Subwoofers

The Kicker SoloX L7X series is built for one purpose: delivering uncompromising bass. From the compact 8-inch SoloX to the massive 18-inch powerhouse, every model incorporates cutting-edge technology designed for both sound quality and sheer volume.

Key innovations include the patented square cone, which increases cone area for louder, lower bass; a massive 31.25 mm Xmax for extreme excursion; and Forced-Air Cooling™, which prevents heat buildup during long sessions. Each driver also features a field-replaceable recone system, allowing quick repairs without replacing the entire subwoofer, a game-changer for serious competitors and daily drivers alike.
