What are the differences between the small BO and large BO audio systems in the Audi A6L?

Here are the specific differences between the small BO and large BO audio systems in the Audi A6L: 1. Number of speakers: The large BO audio system has more speakers compared to the small BO. 2. Power output: The large BO audio system has higher power output than the small BO. Below is additional information about the Audi A6L: 1. Vehicle positioning: The Audi A6L is a domestically produced luxury business car launched by FAW-Volkswagen. The car has a length of 5012 mm, a width of 1855 mm, a height of 1485 mm, and a wheelbase of 2945 mm. 2. Powertrain: The Audi A6L is equipped with a multitronic continuously variable manual transmission that uses a metal chain drive system, completely replacing the traditional gear set transmission method. As a result, the power output is entirely free of jerking, making it smoother than a conventional automatic transmission.

I recently discussed the audio system issues of the Audi A6L on a forum. The difference between the so-called small BO and big BO audio systems is quite noticeable. The former is usually the basic Bang & Olufsen system with fewer speakers, typically 6 to 8, and an output power around 200W, suitable for daily radio or pop music listening—clear sound but lacking depth. The latter, called the big BO audio system, is actually the advanced or 3D version, doubling the speakers to over 10, boosting power to over 1000W, and supporting surround sound and virtual 3D technology. The vocal details and bass effects are particularly impressive, making long drives with classical or electronic music a real treat for the ears. Upgrading to it costs extra; the small BO might be standard, while the big BO is an optional add-on worth tens of thousands—whether it's worth it depends on your budget. When I test-drove, the big BO maintained a pure sound field even with high engine noise on the highway, whereas the small BO required manual volume adjustments to avoid muddiness. But don’t worry, whatever you choose is fine—just avoid unauthorized audio system modifications, as they can easily void the warranty.
