Environmental Speakers designed for consistent sound quality in harsh marine environments.. BOSE 131 environmental speakers let you enjoy quality sound on your boat just as you do at home. Connect to your on-board stereo components & these weather-tested speakers bring BOSE sound to the water, with greater clarity & consistency than you d expect from conventional marine speakers. Each speaker features a BOSE full-range driver for high-fidelity sound. They provide a more consistent sound field than conventional speakers, so you enjoy the clarity & full performance of your music even when you re afloat. BOSE 131 environmental speakers have been designed to flush mount in the pre-cut speaker openings provided by many boat manufacturers. But unlike conventional marine speakers, they feature a proprietary ported enclosure that delivers smooth, consistent low-frequency response. This innovative approach compensates for unpredictable environments behind the mounting locations that can diminish performance. Like every BOSE environmental speaker, 131 environmental speakers are thoroughly weather tested & guaranteed to withstand snow, rain, salt spray & extreme temperatures. If they can handle abuse like this, they ll be right at home in your boat. Compact design
