Sensational surround sound from Bang & Olufsen
Some 14 speakers and two amplifiers create 505 watts of superb sound, balanced to suit the acoustic properties of the car’s interior.
A second digital signal-processing amplifier takes output from standard stereo sources such as CD players, iPods or DAB radios and creates stunning five-channel surround sound. The Bang & Olufsen sound system is optional on the S4 and standard on the S4 Black Edition across the range.
