131® Marine Speakers




131 Environmental speakers

Bose® 131 marine speakers let you enjoy quality sound on your boat just as you do at home. Connect these flush-mounted boat speakers to your on-board stereo components and bring high-fidelity sound to the water, with greater clarity and consistency than you might expect from conventional marine stereo speakers.

Designed to flush mount in the pre-cut speaker openings provided by many boat manufacturers, each Bose 131 marine audio speaker features a Bose full-range driver for high-fidelity sound, and a proprietary ported enclosure for smooth, consistent low-frequency response.


Our proprietary drivers deliver a more consistent sound field than many conventional boat speakers, while the innovative ported enclosures compensate for the unpredictable mounting environments that can diminish performance. With Bose 131 marine stereo speakers, you enjoy clarity and full performance even afloat.

Performance in the extreme

Like all Bose weather resistant speakers, 131 marine speakers are thoroughly weather tested; they are guaranteed to withstand snow, rain, salt spray and extreme temperatures, and are covered by a three-year limited warranty.
