Overview
The three-way car audio coaxial CPX 690 is the best solution for enthusiasts who love highly dynamic listening with low engaging frequencies and want to make the most of the rear deck mount. Tweeter and Supertweeter both feature Neodymium magnet and Tetolon dome, 32 mm and 24 mm respectively. The stylish faceplate is designed to maximize off-axis emissions and thus optimizing horizontal installation. As for the CPX 165, the CPX 690's Tweeter and Supertweeter boasts Radial Venting System technology for outstanding cooling and acoustic performance. The robust basket with radial ventilation keeps operating temperatures low. The supplied grille is made of a high resistance ABS plastic support and metallic mesh to ensure a high level of protection with a Hi-tech design
