Hertz Cento Series CX 690 6" x 9" Three-Way Coaxial Speakers - Pair

Hertz Cento CX 690 is a 6x9-inch 3-way coaxial speaker designed for high output and balanced tonality in horizontal 6x9 locations (rear deck, rear doors). It combines a semi-pressed paper + mica woofer cone (SPP-M) with a 40 mm (1.58") dome tweeter and a 20 mm (0.8") supertweeter to extend top-end response while maintaining strong midbass.

Rated at 100W RMS and 300W peak at 4 ohms, the CX 690 is built to handle real power and deliver strong SPL, with geometry optimized for off-axis listening common in factory-style 6x9 placements.

Key Performance Features

• 3-way 6x9" coaxial for full-range coverage from a single speaker location
• SPP-M cone (semi-pressed paper + mica) for a balance of damping and rigidity
• Wide rubber surround designed for long excursion and controlled output
• High-density ferrite woofer motor with low-carbon pole plates to help reduce distortion at higher power
• 40 mm dome tweeter for efficient mid/high reproduction
• 20 mm dome supertweeter to extend very high frequencies (especially helpful in horizontal installs)
