Hertz UNO X165 6.5" - ideal factory replacement speakers No grilles are included! The 6.5” two way coaxials are available X 165 features a special designed tweeter faceplate optimized for exceptional off-axis performance to ensure a linear frequency response when installed in a factory replacement setup. The pressed-paper cone treated with water-repellent along with the foam surround provide a very high SPL and extended low frequency response, to obtain a rich sound even when driven by the OEM head unit. The 25 mm(1ˈ) woofer voice coil driven by a high-flux density ferrite magnet offers a highly dynamic power handling for a powerful undistorted sound. The easy-to-install DIN size basket, protected by an abrasion-resistant dust paint, makes the factory speakers replacement a snap.
