8"" Solo-Baric L7 Car Subwoofer 2 OHM 11S8L72 - Solo-Baric L7 Subwoofer technology continues to maintain the title as the first and foremost authority on bass. It was the world's first patented square subwoofer supplying the extra decibels needed for deep musical bass in a mobile audio system. The Solo-Baric's cutting-edge square-sub design ultimately means more cone area more air displacement and therefore more decibels than a conventional round woofer. With a patented corner-ribbed double-stitched Santoprene surround helping to hold the massive motor structure in place the Solo-Baric L7 provides durability at a high excursion without compromising sound quality.
