Differentiated design is implemented by taking the image that looks as if the building is brought into the house, instead of the uniform audio image. To maximize the minimal image that is the strength of the product, the design structure without the parting line is imposed. Considering reliability and cost-effectiveness, injection mold hairline and Nano spray are applied. This model is meaningful as a stylish home theater to improve brand awareness with the company product identity, and creates a flagship by applying new materials.
