Alpine MRN-S88-LB 8.8" 2-Way Marine Speakers with RGB LED Lighting - Black

Alpine MRN-S88-LB 8.8" 2-Way Marine Speakers with RGB LED Lighting - Black - 2026

The Alpine MRN-S88-LB brings powerful Alpine Signature Sound to the open water with 150W RMS power handling, strong midbass performance, integrated RGB LED lighting, and an IPX6-rated waterproof design. Built in a bold black finish, these 8.8-inch 2-way marine coaxial speakers are designed to deliver clear, balanced sound even when wind, waves, and engine noise become part of the soundtrack.

Powerful Sound for Open-Water Listening

Why settle for thin-sounding music once you're underway? The MRN-S88-LB is designed around strong midbass performance, giving kick drums, bass lines, and lower vocals more weight and impact. Its long-excursion woofer features a 12.5 mm Xmax, helping move more air for a fuller listening experience.

With 150W RMS and 450W peak power handling, the speakers can deliver energetic output while staying controlled as the volume rises. The 35 Hz–20 kHz frequency response also gives your music plenty of range, from deeper bass through detailed high frequencies.

Carbon-Fiber Hybrid Cone and Silk-Dome Tweeter

The MRN-S88-LB combines a carbon-fiber hybrid cone with a 1-1/4-inch silk-dome tweeter to create a balanced 2-way coaxial design. The cone provides tight, accurate sound, while the silk-dome tweeter helps reproduce smooth, detailed highs.

An integrated passive network helps keep the sound balanced between the woofer and tweeter. Think of it as the speaker keeping each part of the music in its proper lane, helping vocals, instruments, and high-frequency details remain distinct without relying on sheer volume.

Marine-Ready IPX6 Construction

Being on the water demands more from your audio equipment. The MRN-S88-LB features IPX6-rated waterproof construction designed to withstand powerful water spray. It is also resistant to salt, fog, and UV exposure, making it suited for marine and coastal environments.

The speakers use waterproof 2-pin speaker connections and waterproof 4-pin LED connections for added protection against moisture. Salt and fog resistance has been ASTM B117 tested, while UV resistance has been ASTM G154 tested.

Integrated RGB LED Lighting

The black grille gives the MRN-S88-LB a clean, bold appearance, while integrated 4-pin RGB LED lighting lets you add colour to your setup after sunset. Want a subtle glow while relaxing at anchor, or something more energetic for a gathering? The RGB lighting gives you room to create the atmosphere you want.

A compatible controller and remote are required for LED operation. The speakers are compatible with the Alpine KTX-MRN-LED-RF LED Controller & Remote, which is sold separately.

Designed for a Complete Alpine Marine System

The MRN-S88-LB can be used as part of a larger Alpine Marine audio system. Pair the speakers with an Alpine Marine Receiver and add amplification based on the way you want your system configured.

The M-A60F 4-Channel Marine Amplifier can provide 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 stronger low-end performance, a 10-inch or 12-inch Alpine Marine subwoofer can be paired with the M-A120M Mono Marine Amplifier.

The Alpine MRN-S88-LB combines high-output marine sound with the durability needed for life on the water. With 150W RMS power handling, strong midbass, a carbon-fiber hybrid cone, silk-dome tweeter, IPX6 waterproof construction, and integrated RGB lighting, it brings both performance and style to a marine audio system. The black finish adds a clean, modern look, while the marine-ready construction helps the speakers stand up to demanding conditions.
