Modular bass loudspeaker
ลำโพงความถี่ต่ำรุ่น BOSE : MB21 และ MB24 WR ถูกออกแบบมาเพื่อเพิ่มเสียงเบส มีลำโพงขนาด 12 นิ้ว จำนวน 2ดอก, มีค่าตอบสนองความถี่อยู่ระหว่าง 40 Hz - 280 Hz และมีระยะความถี่อยู่ที่ 36 Hz - 290 Hz
The MB24 and MB24 WR low-frequency loudspeakers are designed to provide bass augmentation for Bose LT arrays and other
subwoofer applications. The compact 2 x 12" (305 mm) configuration allows minimal-height arrays when used with LT mid/high
loudspeakers. Bose Modeler® tools and optional rigging hardware make directional bass arrays easy to design and install using MB24
loudspeakers.
