Twelve 2.25-inch (57 mm) full-range 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 

Articulated Array® design provides wide 160° horizontal coverage with 20° nominal vertical coverage for a single module. Actual vertical coverage varies with number of modules in line array configuration. 

Frequency range down to 58 Hz allows full-range speech and light music reinforcement without separate low-frequency loudspeakers. For extended bass and higher output levels, use with Bose Professional MB4, MB12, or MB24 modular bass loudspeakers. 

Optional brackets allow easy installation of single-, double- or triple-stack line array modules
