The BRAVIA A9F OLED TVs combine excellent image quality with impressive sound directly emitted from the screen. This is done using Acoustic Surface ­Audio+ technology which produces sound through screen vibrations. In this way, audio and visual are both emitted from a single source. The overall design appears just as homogeneous, as the screen is supported by a stand with integrated speaker at the backside, so that no addi­tional element is required for the sound.
