This new range of reference component systems fully demonstrates JL Audio's obsession with accurate sound reproduction. Each step of the ZR development process was driven by the goal to create a mobile sound experience like none before. Through the implementation of proprietary technologies and intense optimization of mechanical, electromagnetic and filter systems, ZR raises the bar for automotive speaker performance.Evolution® ZR 5.0 x 7.0 in. / 125 x 180 mm 2-Way Component Systems: 5.0 x 7.0 in. / 125 x 180 mm Woofers; 1.0 in. / 25 mm Aluminum Dome Tweeters. This new range of reference component systems fully demonstrates JL Audio's obsession with accurate sound reproduction.Custom-engineered, proprietary cast aluminum woofer baskets were designed to provide maximum rear open area while also incorporating JL Audio's patented "Elevated Frame" cooling system. This cooling technology, shared with JL Audio's W7 subwoofers, allows air to flow directly across the top-plate and onto the voice coil windings to greatly improve linearity at all listening levels.
