Overview
The DS18 HYDRO NXL-6 is a premium pair of 6.5-inch 2-way marine coaxial speakers engineered to deliver high-output, full-range audio for boats, yachts, personal watercraft, UTVs, ATVs, and powersports vehicles. Available in Matte Black (NXL-6/BK) and Gloss White (NXL-6/WH) finishes, the DS18 HYDRO NXL-6 combines high power handling with integrated RGB LED illumination and rugged marine-grade construction to elevate both sound performance and visual style on the water.
