The CompR sub mounted in the TB features a powerful ceramic magnet, an advanced suspension and superior heat management system for big bass and long life on the road. Our signature double red stitching creates an outstanding bond between the Santoprene® surround and Polypropylene woofer cone for reliable performance under extreme conditions. KICKER’s SoloKon™ technology joins the cone to the vented back brace - both cooling the motor and eliminating distortion for clean, smooth bass. You get all this CompR innovation and technology is in every TB.
