Sound quality meets elegance – with the new S-series loudspeakers every ride becomes a special sound experience. The sophisticated design and the use of the latest technologies guarantee excellent sound characteristics with rich bass, accurate mids and crystal-clear highs.

Nevertheless, these component systems are not only a highlight in terms of sound quality. Our engineers focused on a novel, timeless elegant design as well as on an easy integration into the vehicle. Low installation depths, a removeable aluminum tweeter housing as well as the innovative, two-part “Flex-Crossover” offer much more freedom in terms of connectivity and installation – especially if the tweeters and woofers are separately installed in the door and A-pillar.

Make every ride a special sound experience!
