High-Resolution Audio, hear lifelike audio

Wireless Subwoofer, superb bass without wires

ASC, right sound for any content

Adaptive sound control analyzes content in real time. When ASC detects that you are listening to Dialog it automatically adjusts to allow you crystal clear dialog, when it senses action it raises the sub for more impact.
