This Film speaker has the same characters of existing loudspeaker as well as various things applying to other elec-tronic and electric products. For instance, it is thinner than a paper and can be color-printed with pictures, drawings, and marks on the film. Also, it can be carried rolled up and flexible to form whichever shapes you want. This film speaker had made for Wall speaker. It make wonderful sound and performance and sasy to install in door. As you see, this is the first item for PA used by Film speaker. Thanks. Ted Lim
