Sweeter sound for land or sea

MB Quart's NPT1-116 tower speakers bring outstanding performance and marine-rated durability to your weekend adventures. This tough tower speaker is encased in a strong, lightweight ABS enclosure that protects the speaker while also improving volume and bass response — exactly what you want on your ski boat or ATV.

Quality components for impressive performance

You're buying marine speakers because you demand the best possible sound wherever you go. MB Quart Nautic speakers give you what you want, with quality components and thoughtful design. The 6-1/2" woofer's 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 1" titanium dome tweeter securely in the grille for superior high-frequency dispersion, and eliminating the possibility of water leaking into the woofer's internal works. These efficient speakers deliver maximum output without stressing your amplifier.

Bring big-time power to your tower

MB Quart marine speakers will perform in extreme conditions, with water-resistant components and super-strong composite baskets, magnet covers and grilles. The exterior surfaces are coated with special 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, MB Quart tower speakers are IP67-rated, which means they meet the highest standards of weather resistance

Versatile mounting options

The package includes 11 hardware mounting options, ranging from 1-1/2" to 2-3/4". A centering ring allows the speaker to tip left or right when mounted to an arced mount. A steel mounting plate between the pipe mount and the enclosure adds additional strength. All mounting hardware is die-cast for strength and powder-coated to withstand damaging sunlight, spray, and dust.
