Description of 46L7T102: The only thing thin about the L7T thin subwoofer is the mounting depth. Whether it's on the road or trail, these tough subs work perfectly in nearly anything with a motor.The L7T 10-inch Subwoofer is a true-bass, thin subwoofer with a pair of 2O voice coils. SoloKon technology uses an injection-molded polypropylene cone and 360-degree back bracing as a single solid unit - both cooling the motor and eliminating distortion. . Patented ribbed corners are incorporated into the high-roll Santoprene surround to move smoothly under high SPL. We then stitch the cone to the surround, providing an additional level of integrity that thrives no matter the application. Match any L7T thin sub with a KX-Series mono amplifier for an outstanding combination of power and size.
