The GLADEN Zero 12 PRO is developed for sound quality from the beginning. It is one of the few subwoofers in the market to feature a no-compromise design for sealed enclosures. Thus leading to optimised transient response resulting in sound quality beyond compare. A unique diaphragm technology featuring a sandwich of paper-foam-paper and a sophisticated motor structure made possible thanks to top-class engineering and manufacturing results in deep and accurate bass. Engineered and made in Germany, the GLADEN Zero 12 PRO will be enjoyed by in-car audiophiles all over the world!
