This is Kicker’s original square subwoofer. This sub is what started it all. It is available in 4 model sizes: 8, 10, 12, and 15 inches. Brand new in 2008 the Solo-Baric L7 still carries the SoloKon cone. This one-piece injected cone creates more air movement inside the sub itself. More air moving means louder bass for yourself. The Solo-Baric L7 carries 1000 watts of RMS power and is available in 2 or 4 ohms. This subwoofer was also a best seller in 2008.
