EXTREME PRO AUDIO PERFORMANCE – DS18 PRO-ZT69 6x9” mid-range loudspeaker delivers 275W RMS / 550W MAX, built for loud, clean output and crystal-clear sound in car audio, motorcycle, off-road, and high-SPL systems 2-WAY COAXIAL WITH BULLET TWEETER – Integrated high-frequency bullet tweeter with neodymium magnet produces sharp highs and strong vocal projection, eliminating the need for external tweeters while maximizing efficiency WIDE FREQUENCY RESPONSE (60Hz–22KHz) – Full-range pro audio performance delivers tight midbass, powerful mids, and detailed highs for a balanced, high-impact listening experience at any volume HIGH EFFICIENCY & EASY INSTALLATION – With 98dB sensitivity and 4-ohm impedance, the PRO-ZT69 gets extremely loud on lower power, making it ideal for factory upgrades or high-powered aftermarket amplifiers WATER-RESISTANT BUILD WITH PROTECTIVE GRILL – Rugged water-resistant construction with a steel mesh grill and integrated cloth shade protects against moisture, dust, and sun exposure for long-lasting, reliable performance

DS18 amassed a wealth of experience in manufacturing the most elegant neodymium midranges for those seeking simple perfection. Neodymium magnets provide a higher magnetic flux density in the air gap, which generates a much greater action force in the voice coil. For this reason, Neo magnets have the strongest permanent magnets of all the commercially available speakers. Ranging in sizes, mounting depths, and frequency responses, we have more than 10 different models of Neo midranges to accommodate any build.
