The cabinet is designed with bass reflection and can accommodate a single 15-inch long-stroke driver, various designs allow the maximum sound pressure to reach 140.3 dB. The box body is made of high-density birch board, the front side is equipped with hard wire mesh and black PCP (polyurea cabinet protection) paint finish. It has the function of anti-impact and anti-weather. The unit is supported in the middle of the box by a high precision metal material and metal parts, so that the box can be reliably protected. It is equipped with hangers which can be installed horizontally and vertically at multiple angles. It also has rigging which can be supported and suspended at a single point.
