HITSTM employs a combination of the Torus ScreenTM and a uniquely configured sound reproduction system to create the ultimate sight and sound presentation. The Torus ScreenTM uses a system of compound curves (horizontal & vertical) that are maintained by light mechanical suction pumps behind the screen, which pulls the fabric into the unique shape. Because of the suction, the screen has been designed with no perforations to produce an image of exceptional brightness and clarity.
