Good tunes are critical for any discerning boating audiophile. MB Quart’s NK1 series speakers are water resistant and provide clear and full sound on the water. For boats that can’t accommodate a subwoofer, MB Quart’s 8” NK1-120 Nautic 2-way coaxial speakers are worth a look. They provide deep bass sound and pack a full 130 watts of peak power and 60 watts of RMS. Available with RGB LED lighting systems, the speakers come in a rainbow of colors that can be controlled, along with the sound, by an optional wireless N1-RC remote.
