Description
Bring deep, controlled bass to the water in a compact 10-inch design. Built on Alpine’s legendary R-Series platform, the MRN-W10S4-IB-LW combines powerful output, long-excursion performance, and marine-ready durability.
Protected for Life on the Water
Redefining the Stnadard for Marine Sound Performance
Made for Infinite-Baffle Installations
The MRN-W10S4-IB-LW is optimized for infintre-baffle marine installations, using the open space behind the mounting panel instead of requiring a seperate enclosure. This preserves valuable onboard storage and keeps installation simipler by eliminating the added cost, construction, and enclosure calculations of a traditional subwoofer box. Its compact 10-inch format also helps fit more installation locations. It can also be used in a properly engineered sealed enclosure. Ported conclosures are not recommended.
Powerful Bass That Stays Controlled
Deep bass should feel powerful, not loose or muddy. The MRN-W10S4-IB-LW uses a rigid carbon-fiber hybird cone and high-excurion suspension to keep the woofer moving smoothly and accurately as the volume rises. The result is bass that hits with authority, starts and stops cleanly, and adds impact without overwhelming the rest of the music. Whether cruising at speed, relaxing at anchor, or entertaining at the dock, every track gains a stronger, more controlled foundation with the detail and balance of Alpine Signature Sound.
Distinctive Style with RGB Lighting
A fixed white grille gives the MRN-W10S4-IB-LW 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 subwooofer with Alpine KTX-MRN-LED-RF LED Controller & Remote for convenient lighting control.
Build Your Alpine Marine Bass System
Add the MRN-W10S4-IB-LW to an Alpine Marine system when you want deeper bass without giving up more space than necessary. Pair it with the M-A110V 5-Channel Marine Amplifier for a streamlined speaker-and-subwoofer system, or choose the M-A120M 1200-Watt Mono Marine Amplifier for dedicated bass power and future expansion. Integrated 4-pin RGB LED lighting adds a cusotm glow after sunset when connected to the optional KTX-MRN-LED-RF LED Controller & Remote, sold separately, creating a system that looks as complete as it sounds.
