(2) MB QUART NF1-116 6.5" 80 Watt Marine 2-Way Coaxial White Speakers For Boat

The NF1-116 is a 6.5-inch two-way coaxial speaker built for boat, RV, and off-road vehicle installations, sold as a pair with white grills. Each speaker handles 40W RMS and 80W peak at 4 ohms, and 89dB sensitivity keeps volume up even off modest head unit power. Frequency response runs 35Hz to 21kHz. A .75-inch composite dome tweeter covers high frequencies with high output and low amplifier demand, fed through a clean high-pass crossover network that keeps signal loss down. The midrange cone is water resistant composite polypropylene on a UV butyl rubber surround, which stays flexible in cold weather instead of stiffening and thinning out the sound. A high temperature copper voice coil wound on an aluminum former handles power while staying light, and front and rear venting moves air across it to keep temperatures in check. A woven fiber composite spider holds the cone and coil aligned at high excursion. The poly composite frame adds strength without the resonance that colors tone. Grills are UV treated and integrated into the speaker frame, so installation is a single assembly rather than a separate grill step, and stainless steel screws are included. Protection is rated IPX67 with conformal coated crossover components, UVA certification, and CEA426B testing, which covers salt spray, fresh water, dust, and sand. Cutout is 5 inches with 2.29 inches of mounting depth and a 7-inch outside diameter, sizing that drops into most existing marine and RV speaker openings.
