The Bose Professional MB210-WR outdoor subwoofer has been engineered for permanent outdoor installations where reliable low-frequency performance is required. Designed for background and foreground music as well as small sound-reinforcement systems, deep and controlled bass reproduction is delivered down to 37 Hz. A compact form factor has been combined with high acoustic output, allowing powerful low-end reinforcement to be achieved without occupying excessive installation space.

High performance has been achieved through the use of dual 10-inch high-excursion woofers housed in an exterior-grade plywood enclosure optimized for outdoor use. Long-term reliability has been ensured through weather-resistant construction, an IP55 rating, and industrial protective finishes. Seamless integration has been enabled with multiple Bose Professional loudspeaker families, making consistent tonal balance and extended bass impact possible across a wide range of outdoor commercial environments.

Key Features 

• Dual 10-inch high-excursion woofers
  High-output bass has been produced by two 10-inch woofers derived from the award-winning F1 subwoofer design, allowing strong low-frequency performance to be delivered from a compact enclosure.

• 500 W long-term power handling
  Sustained output and dependable operation have been supported by 500 watts of continuous power handling, making the subwoofer suitable for demanding commercial installations.

• Extended low-frequency response to 37 Hz
  Deep and impactful bass reinforcement has been achieved with low-frequency extension reaching 37 Hz, enhancing music clarity and fullness in outdoor spaces.

• High sound pressure capability
  Maximum continuous sound pressure levels of up to 123 dB, with peak levels reaching 129 dB, have been made possible for consistent performance in larger or noisier environments.

• Weather-resistant outdoor construction
  Direct outdoor exposure has been supported through an IP55 rating, a three-layer stainless-steel grille, water-resistant woofer cone coating, and a durable polyurea exterior finish.

• Flexible mounting options
