Bass That Carries Across the Water
Out on the water, bass has to work harder to be heard and felt. The MRN-W12S4-IB-LB combines 600 watts RMS of power handling with a long-excursion design that moves more air for stronger low-frequency impact. Kick drums hit with greater weight, bass lines feel fuller, and the entire system gains the depth that marine speakers alone cannot provide. Whether cruising at speed, relaxing at anchor, or entertaining at the dock, the music sounds bigger, more energetic, and more complete throughout the boat.
Protected for Life on the Water
The MRN-W12S4-IB-LB is built for the conditions that come with life on the water. IIts IP66-certified dust- and water-resistant construction helps protect against dust and powerful water spray, while salt, fog, and UV resistance support lasting durability in demanding marine environments. Separate waterproof connections protect the speaker signal and RGB lighting wiring, with both mating connectors included for a clean, secure installation. A fixed black and gray grille protects the woofer and maintains a bold, polished appearance season after season.
Made for Infinite-Baffle Installations
The MRN-W12S4-IB-LB is optimized for infinite-baffle marine installations, using the open space behind the mounting panel instead of requiring a traditional subwoofer enclosure. This helps preserve valuable onboard storage while adding powerful, full-bodied bass to the system. Its flexible design also supports use in a properly engineered sealed enclosure when the installation calls for one. Ported enclosures are not recommended, helping keep system planning simple and performance consistent.
Powerful Bass That Stays Controlled
Built on Alpine’s legendary R-Series platform, the MRN-W12S4-IB-LB uses an ultra-rigid polypropylene and carbon-fiber parabolic cone with a high-excursion suspension to keep bass powerful and controlled as the volume rises. A large 65 mm voice coil, double-stacked magnet, and integrated airflow help manage heat during extended playback. Together, these technologies deliver bass that hits with authority, starts and stops cleanly, and gives the music a deep, commanding foundation whether cruising at speed or entertaining at the dock.
Distinctive Style with RGB Lighting
A fixed black grille gives the MRN-W12S4-IB-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 subwoofer with Alpine’s KTX-MRN-LED-RF LED Controller & Remote for convenient lighting control.
Build Your Perfect System
Add the MRN-W12S4-IB-LB to an Alpine Marine system when you want the music to feel as powerful as it sounds. Pair it with the M-A110V 5-Channel Marine Amplifier for a streamlined system that powers both speakers and a subwoofer, or choose the M-A120M 1200-Watt Mono Marine Amplifier for dedicated bass power and the ability to run one or two compatible subwoofers. Integrated 4-pin RGB LED lighting adds a custom glow after sunset when connected to the optional KTX-MRN-LED-RF LED Controller & Remote, sold separately.
