When do I use the BMW coaxial speakers?

If you do not find a separate installation location for a tweeter in your BMW (usually in the rear of the vehicle), you can use the coaxial systems. For this, the tweeter sits on the midrange. However, we recommend the retrofitting of the tweeter installation kit at least in the front area. Ask your BMW dealer about this. (Mirror triangles with tweeter mounting / window frames with tweeter mounting) can be easily retrofitted).
