Anyone interested in high-end sound systems knows that speakers play a vital part in achieving great audio quality, and nowhere more so than in cars. Imagine my surprise, therefore, when I spotted a Mercedes-benz C-class, emblazoned with the words “Speakerless Audio”, that was set up for a sound demonstration at the recent Continental Techshow. The German brand works in the field of active sound cancellation using tiny actuators sited behind the interior panels of vehicles, and this is where the idea of speakerless audio was born. In the C-class, actuators behind the dash, roof liner, seatbacks and other panels vibrate to create sound. Essentially, these surfaces become the speakers and, according to Continental, the system saves weight, is less complex and cheaper than current audio solutions. It also frees up space for interior designers to do with as they please. How does it sound, then? Incredible. The occupants are completely immersed in the sound experience.
