Superior sound and versatile style

MB Quart's NP1-120 speakers bring outstanding performance and versatile style to your boat. Designed for boating or powersports applications, these full-range 8" speakers combine outstanding audio performance with outdoor-ready reliability. And with three different speaker grilles included, you can choose the look that's right for your vessel.

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 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.

Marine-ready components

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, your MB Quart speakers are IP67-rated, which means they meet the highest standards of dust and moisture resistance.

More about MB Quart

Three decades of marine and powersports audio expertise goes into MB Quart's Nautic line. These rugged, high-quality receivers, speakers, amps, and subs provide great sound and all-weather reliability. The MB Quart "Life Shield" badge means your gear has been designed and tested to stand up to the toughest conditions on the water or off the beaten path.

Product Research

Features

Woofer Cone: The woofer cones are made of UV protected injection molded polypropylene.

Mounting Gasket: Polymer gaskets are used to keep the speaker isolated from the mounting surface and improve protection from water intrusion.

Spider: Each speaker uses an aramid fiber composite spider, which will not degrade over time and is not susceptible to temperature changes.

Tweeters: The 1" titanium dome tweeters use waterproof, coated silk surround and are bridge mounted, rather than mounted to a pole piece, thus there is no chance of water leaking through the woofer cone.

Crossover: The Butterworth crossovers have PTC (Positive Thermal Coefficient) tweeter protection and a slope of 12 dB/octave.

UV Protection: The composite grills and frames are UV protected, helping prevent color fade.

Are they waterproof on the back side too?

trav Feb 27, 2025

1 answer

Hey Trav, the spider on the speaker is water resistant but these are not designed to be submerged so I would avoid direct water if possible.

red Feb 27, 2025 (Staff)

If I was to buy 8 of these speakers what would be decent amp to run them with??

dustin Dec 12, 2020

1 answer

Many amps would work, but 100W/ch would sound great. I like Denon, then Yamaha. Why do you want 8 speakers?

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
