About the MB Quart NPW-254
Booming bass for your boat
Booming bass for your boat
MB Quart's NPW-254 10" subwoofer is built for boaters who love big bass. This Nautic-class sub features quality components and thoughtful design, so it'll sound great for seasons to come. And with three different speaker grilles included, you can choose the look that's right for your vessel.
Built tougher to sound great longer
This sub is tough enough for extreme conditions, with water-resistant components and a super-strong composite basket, magnet cover, and grille. The exterior is coated with special UV-resistant paint that stands up to broiling sunlight, and the internals are conformal-coated to protect against fresh and salt-water spray, not to mention dust and sand.
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. It's IPX67-rated, too, which means it meets the highest standards of weather resistance.
Need a light?
If you want to add LED lights to your subwoofer, you can add MB Quart's optional 10” LED light rings (sold separately).

More details on the MB Quart NPW-254
Cone: The subwoofer cone is made of polypropylene, has an NBR (Nitrile Butadiene Rubber) surround, and is mounted on a lightweight fiberglass reinforced composite frame.
Mounting Gasket: A polymer gasket is used to keep the subwoofer isolated from the mounting surface and improve protection from water intrusion.
Spider: The subwoofer uses an aramid fiber composite spider, which will not degrade over time and is not susceptible to temperature changes.
UV Protection: The composite grills and frames are UV protected, helping prevent color fade.
Infinite-Baffle: The NPW-254 is optimized for infinite baffle operation (free-air), so it can be installed in a variety of locations, without the need for a dedicated enclosure. If an enclosure is used, 0.45 ft³ is the minimum recommended volume.
