Elite Screens Spectrum 84 inch Diagonal 16:9 Electric Projection Screen. A home theater system consists of many different elements that need to come together in order to deliver a truly satisfying viewing experience. By far, two of the most important of these elements are the type of display and the sound system. A true home theater experience relies upon the fusion of both the visual and aural elements. If the two are able to complement each other well, the end result is sure to be spectacular. However, if the either element is lacking in terms of quality and performance, the impact is greatly lessened. In terms of visuals, nothing else says “impact” like a colossal screen, such as the Elite Screens Spectrum 84″ Diagonal 16:9 Electric Projection Screen.
