Hertz CX690 Cento Series 6"X9" 300W Peak Power Handling 4 Ohms 3-Way Coaxial Car Speakers (Pair)

• Wide rubber suspension engineered for a long excursion and excellent sound damping.

• High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.

• Basket with metallic finish acoustically combined with a rubber magnet cover for total damping of spurious vibrations.

• 40 mm (1.58 in.) dome tweeter for efficient distortion-free mid-high frequency reproduction.

• 20 mm (0.8 in.) dome supertweeter to maximize the level of very high frequencies in horizontal installations.

• Tweeter faceplate geometry optimized with FEM simulations (Finite Element Modeling), to provide an extremely linear frequency response in off-axis installations.

• Provided elegant grille made with high-resistance ABS plastic structure with a metallic finish combined with a protective metal mesh.
