Bose 251 Environmental Speakers User Manual

The Bose 251 Environmental Speakers are designed to deliver high-quality audio performance in outdoor settings, making them an ideal choice for patios, gardens, poolsides, and other exterior spaces. Below is a comprehensive overview of their features, specifications, and benefits.

Design and Build Quality

• Weather Resistance: The speakers are engineered to withstand extreme weather conditions. They can endure temperatures ranging from -40°F to 158°F (-40°C to 70°C) and have passed rigorous tests for salt fog, humidity, and UV exposure. This makes them suitable for coastal areas or regions with harsh climates.
• Durable Materials: Constructed with a water-resistant polypropylene housing and a galvanized powder-coated steel grille, the Bose 251 speakers are built to last. The materials used ensure that they resist corrosion and physical damage over time.

Audio Performance

• Articulated Array® Design: This unique speaker design positions the drivers in such a way that it creates a wide sound field without distinct “sweet spots.” This means that listeners can enjoy balanced audio regardless of their location relative to the speakers.
• Multi-Chamber Bass Enclosure: The patented design of the bass enclosure minimizes distortion while enhancing low-frequency response. This allows for deep bass sounds even from a compact speaker size.
• Driver Configuration: Each speaker features a 5-1/4” woofer and two 2-1/2” Twiddler drivers made from durable polymer fiber composite cones. This configuration ensures clear highs and robust lows across various music genres.

Installation Features

• Easy Mounting Options: The Bose 251 speakers come with adjustable weather-resistant mounting brackets that facilitate straightforward installation on walls or other surfaces. The included hardware (screws and anchors) simplifies the setup process.
• Vertical Mounting Only: It’s important to note that these speakers are designed specifically for vertical mounting to optimize sound dispersion.

Connectivity

• Compatibility: These speakers can be connected to amplifiers or receivers rated between 4-8 ohms and up to 200 watts per channel. Users will need appropriate gauge speaker wire for installation, which is not included but can be purchased separately.

Warranty and Support

• Limited Warranty: Bose offers a five-year limited warranty on the 251 Environmental Speakers, providing peace of mind regarding their durability and performance.
• Customer Service: Bose provides excellent customer support, including a 90-day return policy allowing customers to test the product risk-free.
