Alpine Marine 8.8-Inch Coaxial Speakers in Black (Pair) - MRN-S88-LB

Alpine MRN-S88-LB Marine 8.8-Inch Coaxial Speakers in Black (Pair)

Built for Big Sound on the Water
Bring powerful audio to your boat with these 8.8-inch black marine speakers. Designed as a 2-way coaxial marine speaker, each unit combines a 6-7/8" woofer with a 1-5/16" hydrophobic Teteron-dome neodymium tweeter for crisp highs and full, balanced sound. With 150W RMS power handling and 450W peak power handling, these marine speakers are made to deliver confident performance for music on open water.

Marine-Grade Construction for Demanding Environments
These black boat speakers are engineered for durability in harsh conditions. The reinforced polypropylene and carbon-fiber cone construction, double linear-rolled Santoprene marine-grade surround, and rigid die-cast aluminum frame with cooling ports all support long-lasting performance. IP66-certified dust- and water-resistant construction helps protect the speakers, while ASTM B117 salt and fog resistance and ASTM G154 UV resistance add another layer of confidence for marine use.

Clean Installation With Integrated Lighting
Designed with convenience in mind, these 8-3/4" marine speakers include a 2-pin waterproof Deutsch connector for the speaker and a 4-pin waterproof Deutsch connector for the RGB LED lighting. The integrated 4-pin RGB LED optical-diffusion grille adds a customizable look to your system, with controller and remote required. Included mounting hardware and plugs help streamline installation, making these marine speakers a strong choice for upgrading your boat audio setup.

Features

• Powerful Sound Beyond the Shore
  Wind, waves, and engine noise can make ordinary speakers lose impact and sound thin once the boat is underway. The MRN-S88-LW 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.
• Built for Life on the Water
  Marine speakers face far more than an occasional splash. The MRN-S88-LW features an IP66-certified construction which helps protect against dust and powerful water spray, along with salt, fog, and UV resistance for added protection in demanding coastal conditions. Marine-ready materials and waterproof speaker and LED connections help defend against moisture, corrosion, sun exposure, and fading. The result is lasting protection designed for real-world boating, repeated exposure, and dependable performance through season after season on the water.
• Designed to Be Seen
  A distinctive white grille gives the MRN-S88-LW a clean, refined presence that complements white fiberglass, light interiors, 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 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-LW 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.
