Pair MB Quart NF1-116SB 6.5" 2-Way Ultra Slim Speakers For RV, UTV, Marine Black

The NF1-116SB is an ultra compact 6.5-inch two-way coaxial speaker with just 1 inch of mounting depth, sold as a pair with black grills. That shallow chassis is the whole point: it fits RV ceilings, boat panels, and side-by-side locations where a standard speaker basket has nowhere to go. Output holds up despite the size, with 40W RMS and 80W peak handling at 4 ohms, 89dB sensitivity, and response from 35Hz to 21kHz. Highs come from a .75-inch composite dome tweeter that reaches high output without much amplifier power, fed through a 6dB high-pass crossover. The cone is water resistant composite polypropylene with a UV butyl rubber surround that stays flexible in cold weather, mounted on a lightweight poly composite frame that resists resonance. A high temperature copper voice coil on an aluminum former plus venting through the spider and back plate keep the motor cool under sustained volume, and a woven fiber composite spider stabilizes cone motion. Grills are UV treated composite integrated into the frame, so nothing fades or rattles loose. LIFE SHIELD testing takes the speaker to marine and motorsports standards for sun fade, fresh and salt water spray, dust, and sand, with an IP67 rating. Cutout is 5.25 inches with a 7.5-inch outside diameter, and the pair weighs 2.6 lb. Universal fitment covers boats, RVs, off-road vehicles, and project builds.
