With the Audi Bose 3D sound system you get two additional speakers in the windscreen pillars which helps create the impression of a greater spatial sound stage and that brilliant feeling of ‘being there’ thanks to the ‘height’ it creates for the music.
This is all created by an intelligent computer program that calculates third dimension information from conventional stereo and then feeds it to the A-pillar speakers thanks to a 558-watt 15‑channel amplifier which drives the 3D sound system. Bose calls this Advanced Staging Technology, which you won’t usually experience in Bose SoundTouch speaker, Bose Solo 5 soundbar, or any of their other home products. This engineering masterpiece was custom-engineered for amazing audio experience in your vehicle.
Look under the boot floor and you’ll see the masterpiece that powers this brilliant sound technology.
Apparently, for those who want to know the technicalities of how this 3D stage is created, a Bose algorithm analyses the components of a piece of music and then positions them optimally on the virtual sound stage, which involves driving 19 speakers.
