ลำโพงคอลัมน์ความถี่กลาง/สูง Bose Professional MA12 ออกแบบมาเพื่อให้เสียงร้องมีความชัดเจนในพื้นที่ที่มีความต้องการเสียงสูง โดยมีระยะครอบคลุมแนวนอนกว้าง 145° ลำโพงคอลัมน์ขนาดเพรียวบางเข้ากันได้กับการตกแต่งเกือบทุกแบบ
สำหรับการใช้งานภายในอาคารเท่านั้น
FEATURES
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
