Multi-Functional Ultra-Low Frequency Speaker System
- Fixed Installation / Mobile Performance Series -
The BW Series is primarily designed for small to medium-sized fixed installations, broadcasting, high-quality conference rooms, home theater surround sound, multi-purpose halls, or front-of-house (FOH) applications in corporate settings. As a key component of FOH systems, this series is primarily used for vocal reinforcement and distributed sound reinforcement applications. Preset digital processors and dedicated analog processors can be selected to optimize the speaker' s frequency response characteristics.
