*drool* Audi has hand-crafted what it calls the Sound Concept, an in-car sound system so excessive it should be able to cause your soft, fleshy bits to pulsate in new and exciting ways. There are five tweeters scattered across the dash and the doors, five woofers (four in the doors and a monster in the back), and then a whopping 52 mid-range speakers encircling the entire enclosure.
