Well with any audio system it takes a certain volume to open up the soundstage. With the B&W that is 40 percent volume at a minimum. When I drive my wife's X5 solo with HK definitely 50 percent. The SDV doesn't change the EQ whatsoever but just increases the volume based on speed to overcome road noise, etc.
As an experiment start out at 50 and see if that changes the overall soundstage (which bass is a part of). That said on my outgoing Lexus it's SDV tried to kick in the equivalent of Logic 7. In my experience with the HK in my wife's 2017 X5 that is not a good thing but at least one forum member has called out better bass experience in an 8-series with HK and it's engagement
