Hertz Uno X 690 6x9-Inch 340W 4-Way Coaxial Speakers

For 6 x 9-inch OEM setups, the Hertz Uno X 690 is a 4-way coaxial speaker delivering 340 W peak power handling. It features a double 15 mm piezoelectric super-tweeter with PEI dome, designed to extend the frequency response above 20 kHz and maximize the stereo image.

The 40 mm PEI tweeter with ferrite motor provides brilliant reproduction of mid-high frequencies and compactness. The tweeter and super-tweeter faceplate are optimized for exceptional off-axis performance.

The woofer features a high-stiffness metallic-grey finish pressed-paper cone with water-repellent treatment and a foam surround combining high sensitivity with deep bass response. A pure copper 25 mm (1 in.) voice coil and high-flux-density 80 mm (3.15 in.) ferrite magnet provide high dynamic power handling for powerful, undistorted sound.

The easy-to-install DIN-size basket is protected by abrasion-resistant dust paint.
