Full Sound for Open Water
Wind, waves, and engine noise can make ordinary speakers lose impact and sound thin once the boat is underway. The MRN-S88-LB is tuned for strong midbass, giving kick drums, bass lines, and lower vocals the weight and energy they need in open-air conditions. Its long-excursion woofer moves more air for greater impact, while 150 watts RMS of power handling helps the speaker stay composed and energetic as the volume rises. A pro-audio-style tweeter waveguide helps direct clear detail through open-air spaces. The result is full, high-output sound that carries across the boat and beyond, keeping the music clear and energetic whether cruising, anchored, or gathered nearby at the sandbar.
Marine-Ready Durability
The MRN-S88-LB is built for more than an occasional splash. Its IP66-certified dust- and water-resistant construction helps protect against dust and powerful water spray, while salt, fog, and UV resistance add durability in demanding marine and coastal environments. Marine-ready materials and waterproof speaker and LED connections help defend against moisture, corrosion, sun exposure, and fading. These protections support dependable performance and a clean black appearance through repeated use and changing seasons on the water.
A Bold, Integrated Look
A distinctive black grille gives the MRN-S88-LB a bold, refined presence that complements dark interiors, black trim, and modern marine finishes. Integrated 4-pin RGB LED lighting shines through an optical-diffusion grille for a smooth, even glow after sunset, creating anything from subtle accent lighting to a more energetic atmosphere onboard. LED operation requires a compatible controller and remote, sold separately. Pair the speakers with Alpine’s KTX-MRN-LED-RF LED Controller & Remote for convenient lighting control.
Clarity for Open-Air Listening
Marine sound has to project without becoming harsh or tiring. The MRN-S88-LB uses a reinforced polypropylene and carbon-fiber cone to keep midbass tight and controlled as the volume rises. A hydrophobic 33 mm dome tweeter resists moisture, while its pro-audio-style waveguide helps direct high-frequency detail through open-air spaces. An integrated 2-way crossover blends both drivers for balanced Alpine Signature Sound, keeping vocals, instruments, and percussion distinct from the helm to the stern, even as wind and engine noise increase.
Build Your Ideal Alpine Marine System
Creating the ideal Alpine Marine system means bringing the source, amplification, speakers, and bass together around the way you listen on the water. Start with an Alpine Marine Receiver, then add amplification that matches your system goals. The M-A60F 4-Channel Marine Amplifier delivers dedicated power for four speakers, while the M-A110V 5-Channel Marine Amplifier can power four speakers and a subwoofer from one compact solution. For deeper, more commanding bass, pair the speakers with a 10-inch or 12-inch Alpine Marine subwoofer and the dedicated M-A120M Mono Marine Amplifier. Together, each component contributes to clear, balanced Alpine Signature Sound from bow to stern.
