The DS18 NXL-IQ7.7 is a 7.7 inch marine-grade 2-way coaxial speaker set built for loud, clear open-air sound with integrated lighting. Rated at 175 watts RMS per pair and 350 watts max, with 96dB sensitivity and a 40Hz to 20KHz frequency response, it delivers strong output with clarity and control.

This coaxial design combines a 7.7 inch woofer with a 1 inch floating bullet tweeter for defined highs and detailed full-range performance. The woofer uses a 1.5 inch glass fiber voice coil former with CCAW winding, PPI cone and dust cap, and a rubber surround, driven by a hybrid Ferrite plus Neodymium motor system.

Lighting is fully integrated, featuring digital LED backlighting behind the cone plus a white deck LED on the front cover. LEDs connect through a 12V and digital input terminal, using 1815S chips.

Made for marine use, the NXL-IQ7.7 is IP65 rated with UV protection, and uses injection molded composite materials with UV protection coating. The included injection molded composite ASA grill has a UV protection coating, finished in matte black. Recommended high-pass crossover is 50Hz.
