MB Quart’s NF1-116B speakers bring outstanding performance and durability to your boat. Designed for boating or powersports applications, these full-range Nautic Series 6-1/2 speakers combine outstanding audio performance with outdoor-ready reliability. Built to deliver impressive performance. MB Quart Nautic speakers give you the performance you demand from your marine speakers, with quality components and thoughtful design. The UV-resistant polypropylene cone is attached to the frame with a durable butyl rubber surround and stabilized with a woven aramid fiber spider that resists weather- and temperature-related degradation. MB Quart mounts the 3/4 composite dome tweeter securely in the grille for superior high-frequency dispersion, while eliminating the possibility of water leaking into the woofer’s internal works. These efficient speakers deliver maximum output without stressing your amplifier. These rugged speakers are made for boating, with water-resistant components and super-strong composite baskets, magnet covers and grilles. The exterior surfaces are coated with UV-resistant paint that stands up to broiling sunlight. Inside, the crossover network is conformal-coated to protect against fresh and salt water spray, not to mention dust and sand. In fact, they’re IPX67-rated, which means they meet the highest standards of dust and moisture resistance. More about MB Quart.
