LM series linear array box, low-frequency reflective acoustic design. The box body is made of high-quality splint materials, and the inside is treated with scientific sound wave structure. The appearance adopts a novel and unique pendant structure, which is safe and reliable. It can be hung, supported and placed on top of each other, and the installation is convenient and flexible. The carefully selected high-performance loudspeaker unit, coupled with a compressed high-frequency horn, effectively guarantees the large sound pressure and long-distance transmission of sound waves. The scientific structure design ensures that the phases of multiple stacks are consistent, the acoustic interference is small, and the transition is smooth and natural. The overall sound quality has good low-frequency dynamics, obvious sense of strength, bright and transparent mid-to-high frequencies, strong penetrating power, and good musical and vocal expressiveness.
