Got my 2010 xf premium a week ago.

I was reading in other threads how the BW system has yellow speaker cones.

As far as I know my car doesn't have the upgraded sounds system. ( no BW badging on speaker grills).

However my speakers appear to have the yellow cones behind the grills.

Might I have the BW system without any labeling? Or are all the speakers yellow?

How can I otherwise tell?

 

You got lucky : free B&W speakers

 

From what I remember, 09-11 xf comes with bw speakers. Actual BW systems will come with a better amp and a few more (surround, and center) speakers.
