| Low-Frequency | 12 × 2.25 in (57 mm) high-excursion mid/high-frequency drivers |
- Twelve 2.25-inch (64 mm) drivers mounted in a vertical line array deliver wide horizontal coverage with narrow vertical pattern control
- Modular design allows stacking of multiple enclosures in a line array configuration to provide increased vertical pattern control which improves “throw” distance and reduces unwanted floor/ceiling reflections
- 145° horizontal × 20° nominal coverage for a single module. Vertical coverage varies with number of modules stacked in line array configuration.
- Mid/high configuration allows bass management and design flexibility. Use with Bose Professional MB4, MB12, or MB24 modular bass loudspeakers for full-range reinforcement.
- Optional brackets allow easy installation of single-, double- or triple-stack line array modules
