Musway CSB-4.2C - BMW 2-Way Speaker Set with 10 cm Midrange Driver
The Musway CSB-4.2C is a vehicle-specific 2-way speaker set for many BMW E, F, and G series models (excluding F15/F16 front doors). It combines a 10 cm midrange driver with a fiberglass cone and a 25 mm titanium tweeter for a precise upgrade to the factory system. Thanks to Plug+Play connections, installation is quick, and the shallow mounting depth of 43 mm provides additional leeway. If there is no space for the tweeter in your vehicle, suitable mirror triangles are available as spare parts.
