The Bose 251 Environmental Speakers are premium outdoor speakers engineered to deliver wide, consistent sound coverage in open-air environments. Featuring Bose’s proprietary Articulated Array® design, precisely positioned drivers create a large, balanced sound field—perfect for patios, gardens, decks, or pool areas.

Built to withstand harsh weather, Bose environmental testing simulates exposure to sun, rain, heat, ice, salt, and water, ensuring reliable, long-lasting performance year-round. The rugged cabinet is made from mineral- and glass-filled polypropylene for enhanced durability, while weather-resistant brackets and hardware support secure outdoor installation.

A proprietary multi-chambered enclosure minimizes low-frequency distortion, allowing the 13.3 cm woofer to deliver deep, full bass. Dual 6.4 cm full-range drivers in the Articulated Array® configuration produce lifelike, consistent sound across a wide listening area, while specialized driver materials resist deterioration in extreme conditions. Syncom® computer testing further ensures exceptional quality and reliability.

Designed for powerful outdoor performance with clarity and durability, the Bose 251 Environmental speakers bring high-quality audio to any outdoor living space.
