DS18 S69
The DS18 S69 is a pair of 6×9‑inch 3‑way coaxial car audio speakers engineered to deliver full‑range sound with strong bass, clear mids, and crisp highs for everyday listening and upgrades to factory audio systems. With a nominal impedance of 4 Ω and 80 W RMS / 240 W peak power handling, these speakers produce dynamic output with good efficiency and detail. Their frequency response spans approximately 35 Hz to 20 kHz, allowing deep low end and bright highs with a sensitivity of 90.8 dB, making them easy to drive with most head units and amps. The woofer uses a PPI cone with a rubber surround for controlled excursion, while dual tweeters provide enhanced high‑frequency clarity. Constructed with a rugged steel basket and finished in matte black with included protective grills, the S69 speakers are versatile and visually appealing upgrades for car doors, rear decks, or other custom installations.
