The 6.5-inch two-way coaxials, X 165, boast a uniquely designed tweeter faceplate optimized for superior off-axis performance, ensuring a linear frequency response when installed as a factory replacement. The pressed-paper cone, treated with water-repellent, and foam surround deliver an exceptionally high SPL and extended low-frequency response, producing a rich sound even when driven by the OEM head unit. The 25 mm (1-inch) woofer voice coil, driven by a high-flux density ferrite magnet, offers highly dynamic power handling for a powerful, undistorted sound. The easy-to-install DIN size basket, protected by abrasion-resistant dust paint, simplifies factory speaker replacement.
