A surround sound system from Bowers & Wilkins with diamond tweeters is available for the first time in the all-new BMW 5 Series range. This optional highend audio system is renowned for delivering the ultimate in listening pleasure. The 10-channel amplifier feeds a total of 16 speakers with brushed stainless steel grilles sporting the exclusive Fibonacci-patterned holes, which illuminate when the system is switched on. Total output is an impressive 1,400 watts. A measuring microphone is built into the car to allow the acoustics to be precision tuned to the specific conditions - for example, the number of occupants - in order to create a flawless surround sound experience for everyone in the car. What's more, the sound setting can be matched to the selected music genre.
