But the audio experts are at least working on both. For this purpose, DS uses special sound-absorbing foils in the doors or other cavities for its high-end system in cooperation with Focal and also reinforces the side windows with noise-absorbing glass layers. In addition, Buisson-Descombes and his colleagues work just like their competitors on new tweeters, woofers and mid-range speakers and the optimal shapes and installation positions for them. A tough battle with the car designers, who also need the space for batteries, shelves, airbags, auxiliary engines or computers. This is one reason why the trend is towards more and more and smaller loudspeakers. Even in the compact SUV DS4 there are already 14 units.
