Composed of two 4.5-inch 25mm voice coil full frequency units and one 25mm compression driven tweeter, with a built-in passive frequency divider full frequency speaker;

The 4.5-inch unit uses a fabric folding ring formed by hot pressing, with high power and high sound pressure;

The system uses 2.5-6mm aluminum alloy extrusion and stretching surface treatment with sandblasting electrophoresis, waterproof and UV resistant process, corrosion resistance, and good performance;

Multiple internal reinforcing ribs are made of aluminum alloy profiles;

Each box has two sets of power input connection ports on the back, which can also be used for parallel box function;

Considering strength, aluminum alloy molds are specially thickened by 2.5 times at the horn and back support positions;

Convenient for use when combining horizontal linear arrays. At the same time, there is a reserved pipe mouth on the base;

Suitable for classrooms, conference rooms, lecture halls, shopping malls, high-speed rail stations, airports, cafes, home theaters, Hi Fi viewing, and other purposes;
