Alpine MRN-W10S4-IB-LB 10" 4-Ohm Infinite Baffle Marine RGB Subwoofer - Black - Each - 2026
The Alpine MRN-W10S4-IB-LB brings deep, controlled bass to your boat in a compact 10-inch design. Built on Alpine’s legendary R-Series platform, this marine subwoofer combines 600W RMS power handling, long-excursion performance, RGB lighting, and an IP66-certified construction designed for life on the water.
Powerful 10-Inch Marine Bass
Why settle for flat-sounding music when you can add real depth to your marine audio system? The MRN-W10S4-IB-LB delivers 600W RMS and up to 1,800W peak power handling, giving bass lines, kick drums, and low-frequency effects more weight and impact.
Its 20 mm Xmax allows the subwoofer to move more air for powerful low-end performance, while the 84.5 dB sensitivity and 30 Hz – 150 Hz frequency response help create a fuller foundation for your music. Think of it as the part of your system that fills in the low-end gaps your regular speakers simply cannot reach.
Designed for Infinite-Baffle Applications
The Alpine MRN-W10S4-IB-LB is optimized for infinite-baffle installations, making it a practical choice when onboard space is limited. Instead of requiring a traditional enclosure, it can use the open space behind the mounting location.
The subwoofer is also compatible with sealed enclosures when properly engineered, but ported enclosures are not recommended. With its 10-inch format, 9-1/16-inch cutout diameter, and 6-3/4-inch mounting depth, it offers a compact way to add serious bass without taking up unnecessary space.
Built for Life on the Water
Marine audio equipment has to deal with conditions that standard car audio gear doesn't. The MRN-W10S4-IB-LB features an IP66-certified dust- and water-resistant assembly designed to handle demanding marine environments.
The subwoofer has been tested for salt and fog resistance using ASTM B117 testing and UV resistance using ASTM G154 testing. Its waterproof speaker and RGB connections add another layer of protection, helping keep the connections ready for the conditions found onboard.
R-Series Construction for Controlled Bass
The MRN-W10S4-IB-LB uses an ultra-rigid polypropylene and carbon-fiber parabolic cone paired with Alpine’s High Amplitude Multi-Roll (HAMR) surround. This combination supports the long-excursion movement needed to produce strong bass while maintaining control.
A 65 mm single voice coil and double-stacked strontium ferrite motor provide the foundation for its 4-ohm design and high power handling. The result is bass designed to stay impactful and controlled as you turn things up.
Integrated RGB Lighting
The fixed black grille gives the MRN-W10S4-IB-LB a clean look, while integrated 4-pin RGB LED optical-diffusion lighting adds a visual element after dark. The lighting can provide anything from subtle accent illumination to a more energetic atmosphere on the water.
A controller and remote are required for LED operation. The subwoofer is compatible with Alpine’s KTX-MRN-LED-RF LED Controller & Remote, which is sold separately.
Built to Complete Your Marine Audio System
The Alpine MRN-W10S4-IB-LB can serve as the low-frequency foundation of an Alpine marine audio setup. Pair it with the M-A110V 5-Channel Marine Amplifier for a streamlined speaker-and-subwoofer system, or use the M-A120M 1200-Watt Mono Marine Amplifier when dedicated bass power is the priority.
Add the optional KTX-MRN-LED-RF controller and remote to take advantage of the integrated RGB lighting and give your system a coordinated look after sunset.
The Alpine MRN-W10S4-IB-LB is a strong choice when you want deeper marine bass without giving up more onboard space than necessary. Its R-Series construction, 600W RMS power handling, infinite-baffle design, marine-ready protection, and integrated RGB lighting bring both performance and style to your audio system. Add the right amplifier and optional RGB controller, and you have a compact subwoofer built to bring more weight and energy to your music on the water.
